AMD might have an answer), you normally want to stay away from. You can limit CPU resources on the container level. This is only enforced when CPU cycles. If the tag is omitted or equal to latest the driver will always try to pull the image. This works quite well, but there is this one large performance issue: High CPU load (up to 100%) in the MariaDB container, causing in . Please note that CPU time is throttled only when the host CPU usage is maxed out. It doesn’t mean that a container has that much usable resources. Conceptually, header CPU % means max 100%. These accidental DBA's need to know what happened in the system in a chronological order or even worst need to know what led to the lead up to a particular problem. A container is meant to run a specific daemon, and the software that is needed for that daemon to properly work. A #Container is an isolated environments that. Percentage of time in kernel space normalized by the number of CPU cores. Very often people link high server load to high CPU usage. $ docker stats CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS fc015f31d9d1 0. In this case, the fieldpass gets applied for other measurements like ‘docker_container_cpu’ as well. The i386 processor operates at 3600 MHz, and has an i387 compatible floating point processor. You can compare this result to the CPU and memory settings in the Docker app preferences. Observing performance is a key method of maintaining proper performance. hyperkit takes up a normal amount of CPU. The on-premises data gateway has settings that control resource usage on the machine where the gateway is installed. When attached in the tty mode, you can detach from the container (and leave it running) using a configurable key sequence. It's being a good boot camp on Kubernetes. nr_periods: The number of period intervals that have elapsed: docker. We’ll break down the following into two parts. data -a -g -e cycles:p -- sleep 10.

By default, gateway releases starting in June 2019 (3000. The step-by-step guide here describes a manual/on-demand investigation. It is usually (for the most part) fine. Similar to the memory reservation, CPU shares play the main role when computing power is scarce and needs to be divided between competing processes. The default is 1024, higher numbers are higher priority: $ docker run --cpus=2 --cpu-shares=2000 nginx. Most of these inserts are to the same table. js application inside a docker container, traditional memory parameter tuning does not always work as expected. However, like any large research level program it can be challenging to install and configure. For instance, in MySQL docker image, "/etc/mysql/conf. I tried running just the part of my code that uses opencv directly in the container dustynv/jetson-inference:r32. From my understanding, the CPU % returned by docker stats can be greater than 100% if multiple cores are used. AppSignal reports the same metrics as the docker stats command, but reported as an average on a minutely basis. Usually once the second user starts testing the platform crashes. You can also setup this monitoring infrastructure without using Swarm, but it might become hard to manage when you add or remove nodes on your. The Docker stats command provides an efficient yet effective snapshot of resource-usage and is ideal on a smaller scale, such as a limited number of containers on a single host. Starting from the first-day docker promised us strong guarantees of isolation. Here is our example with 6 nodes instead of 3. CPU is reported as % of total host capacity. Unfortunately, a 'top' command on the . There are 8 LXC containers running, but seven of them show 0% RAM usage and the last one shows 1%. makes sure stuff is running in the place and quantity that you want and manages that process). I had the same problem (a container was running out of memory) on Windows 10 with Docker for Windows 17. wslconfig like the example below:. The first step of investigation was to find out the Docker container that was causing the 100% CPU usage. Docker Desktop is a desktop app (GUI and all) while all the listed alternatives are terminal apps. Describe the results you received: CPU column shows values above 100% (110%, 250%) Describe the results you expected: CPU column values should be normalized to 100%. We are already familiar with the official docker PHP image but have only used the cli-only version so far. The container allocates all of the available 200% CPU capacity (per CPU you have 100%) to get its job done. Limit how much CPU a container can use. 0, security is enabled by default. It is a tool for testing CPU usage, memory usage, and disk IO and MySQL performance. The command for running an Ubuntu container with access to 1 CPU would be: sudo docker run -it --cpus="1. Redis-cli is totally unresponsive. You don’t get lightning-fast performance out of the box without Docker performance tuning. Maximize Docker's potential by implementing best practices to improve security, speed, and efficiency. Docker: Placing limits on cpu usage in containers.

Let's check out the charts in Figures 1 and 2 to get an idea as to how to compare the class sharing methodologies. What Mesos does is, it provides isolation for the Memory, I/O devices, file systems, and the CPU. Having out-of-disk creep up on you on these kind of hosts is most unexpected. If the image to be pulled exists in a registry. # 20 seconds NO LIMIT docker run -d --rm progrium/stress -c 8 -t 20s The container allocates all of the available 200% CPU capacity (per CPU you have 100%) to get its job done. Many times when we troubleshoot a problem with high CPU, its asked that when it all started and do we have any historical data of CPU usage?. The YAML file defines all the services to be deployed. When I jump into the docker container I see that node is only using 54% of the CPU and that the processing is split between the two cores. Sadly this isn’t fixed in Java 8 or Java 9. A healthcheck is how you tell Docker to test your app is really healthy, so if your web process is maxing out, Docker can mark the container as unhealthy and take evasive action (in swarm mode Docker replaces unhealthy containers by spinning up replacements). We posted a DockerCon 2018 update last year, and it is time to share how we've improved the experience of using. Hello all, hoping for some guidance. Each method on APIClient maps one-to-one with a REST API endpoint, and returns the response that the API responds with. After some testing, I found this to be incorrect when running a Spring Boot jar in a Docker. docker run starts a process with its own file system, its own networking, and its own isolated process tree. So, this should max out at 200% for this VM. I'm a bit confused here as I'm using docker-compose with no resource limits, the container should use all available 16 cores. I took down all dockers and everything seems to be fine. In short, the JVM will look at the hardware and detect the amount of CPU's there are. Read about this exciting feature, create a free Codefresh account, and try building, testing and. Most users do not change this from the default.

A list of all published Docker images and tags is available at www. We’re going to discuss some of the tips and tricks to ensure you are utilizing the real speed of containers. Click the + Graph button on the right then choose the docker metrics to display the graphs. You can also use the --cpu-shares option to give the container a greater or lesser proportion of CPU cycles. It can run the Docker containers on an EC2 instance that you provision and can access, or it can run them on Fargate. The CPU usage on docker embedded host is ~3%. At any time you can run docker ps in the other shell to view a list of the running containers. Passive benchmarking with docker LXC and KVM using OpenStack hosted in SoftLayer. Upon investigation the java service is the culprit. However, most of steps above may be automated by container orchestrator or infrastructure. The "warm" container that used the method described above of pre-warming a Docker image with class data; Each image was ran ~30 times, and their run time and max memory usage were collected and presented in the following figures. 4GHz and 16GB RAM so I wouldn't think that CPU would be this massive an issue at such an early stage. It auto-discovers all containers in the given node and collects CPU, memory, filesystem, and network usage statistics. For most use-cases, --cpus is a more convenient alternative. Testcontainers is one of the most popular use cases for Docker on desktops. It describes some of the many ways Node-RED can be run under Docker and has support for multiple architectures (amd64, arm32v6, arm32v7, arm64v8 and s390x). In short, the JVM will look at the hardware and detect the amount of CPU’s there are. It follows that a 1000m CPU limit would be more than enough capacity under normal operation. 4) Get the Anaconda3 install shell archive file, 5) Create a file called bazel. Also, not so high as to overwhelm CPU (s) and have a pile of pending PHP-FPM operations. While adjusting some environment variables recently, I came across an odd issue with Docker, Spring Boot and JAVA_OPTS. Therefore all running PODs are slow to respond. I use Docker in combination with Lando for local . The architecture covers high level install/configuration, provisioning process and the solution testing required for CVD. Provided the system has CPU time free, a container is guaranteed to be allocated as much CPU as it requests. Newsdemon unlimited (27 connections to US, 22 to EU), EasyNews and Farm blocks. You define limits as parameters when creating containers. If you haven’t specified the CPU usage for a container, the stats command will show the total memory available in the host machine. JAVA_OPTS comes from the Tomcat/Catalina world and when searching for "Docker and javaopts" on Google you'll find many references to just adding JAVA_OPTS to the Docker environment. Specifically it refers to the cpu-shares. cAdvisor exposes Prometheus metrics out of the box. It is always advisable to mount the config files of services from outside the Docker container. 4 CPU operations per 10 seconds / Sysbench. docker run --rm -d --name clocksource-cpu-test appian/docker-clocksource-cpu-test. memory: (docker option: --memory) should be specified with a suffix of b (bytes), k (kilobytes), m (megabytes), g (gigabytes). By default, LXD CPU-pinning in this context will systematically outperform the native scheduling of Docker and Kubernetes. Check out Top 10 Docker Logging Gotchas to see some of the best practices we discovered along the years. The same could be said of having the -p port forwarding option default to binding to 0. I have a docker swarm overlay network that connects 6 nodes each running 4 containers with highly frequent communication. A container is a unit of software that packages an application, making it easy to deploy and manage no matter the. To check the memory limits in bytes inside a container, issue the. However, with the new Apple's M1 Laptop, running on ARM CPU, a whole new generation of developers discovered that Docker (or I should say OCI) images are not working everywhere, or at least are built for specific CPU and OS. Docker provides packages that configure the Docker environment on macOS, Windows, and Linux. 04 we not be capable of setting limits. The metrics will also be available to select when building dashboard graphs. yml file and deploy a sample app consisting of a custom flask program and a stock redis container to amazon's Fargate Container service in like 3 command line steps!. Status of virtual processor 1 as of: 01/31/2016 20:15:15 on-line since 01/31/2016 20:12:59. You don't get lightning-fast performance out of the box without Docker performance tuning. +1 for @David Maze at least for the answer. I have been trying to identify the bottleneck with my network to realize that the culprit is the ksoftirqd process related to the docker swarm networking that uses up all the CPU in the manager node and causes my app to crash. By using Ansible for cluster management, it also becomes incredibly easy to scale horizontally to other hosts by changing the port binding from localhost to an IP address that's routable. To make it short: all Docker images previously built on Intel or AMD CPU were not working on these new laptops running on. You can write programs in OpenCL and run them on a variety of devices, including CPU, But by the. 7 that hosts some docker instances and they work perfectly 95% of the time. This blog post explains how you can configure setup a monitoring stack easily using Docker Swarm, Grafana, InfluxDB and Telegraf. Take note of the highlighted columns, self-explanatory. Docker recently announced a neat plugin for their 'edge' version of docker desktop that allows you to take your docker-compose. To limit a container’s CPU time use –cpus option. This tool is designed to leverage the features of modern kernels in order to carry out functions like resource isolation, prioritization, limiting & accounting. On the Sysbench tool test conducted to find out the time required to perform the max imum prime number. If you want to plan for future Nano, maybe sending streams into an Nvidia-docker container on x86. I'd recently installed Docker plus turned on WSL (linux) on my Win 10 machine. Before we move on, let's clean up. cpu docker run —cpu-shares=max(requests . From the comments and edits, these stats may check out. Here, we have two main choices: CPU shares and CPU sets. Because Docker containers, from the outside, can look a lot like black allocated the same CPU shares by Docker, and each using max CPU, . After running the code I noticed that I get much less fps than I got outside the container. Docker makes it possible to restrict containers to a particular CPU core, or set of CPU cores. To limit a container's CPU time use -cpus option. Docker must be configured to allow the containers to connect with and send billing data to Azure. $ docker run-e "MAX_QUEUE_LENGTH=10"-p 3000: If you want opt-out of this behavior, start the docker image with this flag: Sometimes it's helpful to have it restart automatically when CPU or Memory usage are above 100% for a period of time (by default 5 minutes). js issue (if you don't have this problem). What gets me is that this only occurs on my Linode. For containers, the docker daemon will create a docker directory under /sys/fs/cgroup/cpu directory, then create sub-directories inside . To upgrade a Docker MySQL Container, you can follow the steps mentioned below: Step 1: Stop the MySQL Server for this instance using the code snippet mentioned below: docker stop mysql57. When using older versions use force_update: true to trigger the swarm to resolve a new image. The Docker daemon pulled the "hello-world" image from the Docker Hub. CPU temperatures and fan speed readings via TG Pro: (affiliate link) Related Docker videos: ️ Docker on M1 MacBook vs Ryzen 7 Lenovo - ️ M1 MacBook SSD and Docker - ️ Apple M1 vs Intel Core i9 and Docker Preview - First Look - ️ M1 With Docker Live Stream - ️ Apple M1 and VSCode Performance -. Hi, I'm running a docker container with nextcloud 20. I know IO has a penalty in docker, so I made all my queues durable=False, with no change. 00% 482MB / 205MB 0B / 0B 0 64bf92bf228d renderer 0. So if you have two containers each using as much CPU as they can, each allocated the same CPU shares by docker, then the stat command for each would register 50% utilization, though in practice their CPU resources would be fully utilized. Docker images can support multiple architectures, which means that a single image may contain variants for different architectures, and sometimes for different operating systems, such as Windows. Home Assistant Docker sensor · GitHub. We specify such a limit by using the --cpus argument when using docker run:. We can build an image from a Dockerfile in the current directory using the 'docker build' command. Hey folks - I'm trying to debug why dockerd on one of our bare metal servers is pegging our cpu at 100% for a few days now. See the Docker Hub tensorflow/serving repo for other versions of images you can pull. docker update --memory 400M --memory-swap -1 vote [Output] vote Let us check whether the change has taken effect or not with docker stats terminal. The CPU % column reports the host capacity CPU utilization. Each of these is a single value, analogous to its docker service create counterpart. Indeed, some containers (mainly databases, or caching services) tend to allocate as much memory as they can, and leave other processes (Linux or Win32. Identifying the problem container. While looking at a different issue at a client site, I noticed an Availability Group secondary node using 25% of the CPU on a server. The actual amount of CPU time will vary depending on the number of containers running on the system. The problem then is: CUDA cannot currently run in Docker on Nano (but support is planned). The --cpu-quota option specifies the number of microseconds that a container has access to CPU resources during a period specified by --cpu . We can just go ahead and say that using cpu shares is the most confusing and worst functionality out of all the options we have. I tried tweaking the number of CPU cores for the Docker engine. Three and a half ways of running Docker on Windows and macOS. My Container Station Overview is showing 74% RAM usage, but the system is only showing 13%. Containers themselves are light, but by default a container has access to all the CPU resources the Docker host kernel scheduler will allow. You can reattach to a detached container with docker attach. issue happens only occasionally): $ grep -c ^processor /proc/cpuinfo 2. You would max out your entire Docker Host if you were to start a stress worker processes for each CPU core. one benchmark run takes 100 seconds and the next one takes 1000 seconds, something has. We can set the CPUs limit using the cpus parameter. Here's a guide to measuring Percona server Docker performance, with a focus on CPU and network overhead. CPU: 4 Minimum (I am using 8 CPU) HDD: 80GB (I am using 200GB) Host OS: Any OS which can run Docker engine (I am using Ubuntu Server 20. I have seen a number of customers manage their SQL Server environments in an adhoc manner. The issue: After about 12 to 48 hours (roughly, different each time) redis-server (top command calls it "redis2" sometimes and "redis-server" other times) suddenly consumes all the CPU it can, more or less bricking the whole system. docker service create --name=nginx --limit-cpu 0. Images will only resolve to the latest digest when using Docker API >= 1. No doubt about it, the 2021 Macbook (Pro) with the M1 (Max) processor is a powerful, fast, silent and „cool“ workhorse – and although it has lots of power I don’t think you will hear or feel it cool down very often, as opposed to its predecessors. For example, if you have two containers, each allocated the same CPU shares by Docker, and each using max CPU, the docker stats command for each container would report 50% CPU utilization. It seems to be happening every now and then on ARM64 during initial data sync, but is not limited to the RaspberryPi. Running Docker Containers on Synology NAS is explained in this article. i was running out of disk space before for docker (not on the host - there's ~1. The primary node was only using 2%, and the other secondary was only using 2% CPU, and. 15+), and Docker as described in the last tutorial. No Download station, no docker, no VM. On the new versions of Docker, running docker stats will return statistics about all of your running container, but on old versions, you must pass docker stats a container id. Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 142 Model name: Intel(R) Core(TM) i5-7200U CPU @ 2. sudo docker run -it -m 8m --memory-swap 8m alpine:latest /bin/sh. You have seen how it is possible for a single container to max out CPU resources on a Docker Host. You can use the docker stats command to live stream a container’s runtime metrics. To generate this message, Docker took the following steps: 1. Although Docker is actually heavily used for MicroServices, installing such a monolith works as well. Copy and paste the following YAML file, and save it as docker-compose. 00% 21kB / 0B 0B / 0B 0 938bcdd26eeb grafana 0. Although not an answer to your question (your PC manufacturer or. As a result, we figured out many tricky moments about Java in Docker regarding memory and found the way to decrease its consumption via refactoring and migration to Spring Boot. VMMEM continued to churn the CPU. The docker driver supports the following configuration in the job spec. Now we need to build the container. The Docker client contacted the Docker daemon. Any configuration changes for MySQL service can be done without affecting that image. The top reason for MySQL induced server load is due to memory or I/O exhaustion. I'm currently running the example-voting-app tutorial. On Windows, Docker must also be configured to support Linux containers. WSL removed, no Docker services running. But not sure where that base 100 is coming form. Earlier today I've realised my CPU is 100% used by a strange process, that after some research I found it is related to crypto-mining. Unfortunately, a 'top' command on the Docker host will not work here. Really, I would recommend to just pass the newest CPU that qemu can emulate (probably -cpu max). Collect docker container resource usage. After all, installing NW ABAP into Docker means we're installing a fat monolith into Docker (65 GB after installation incl. hyperkit ) with no containers running and . nr_throttled: The number of times tasks in a cgroup have been throttled: docker. Noone logged on Plex, actually. 어떻게 pod 리소스 제한은 동작하는가? requests와 limit이 사용하는 docker 옵션이 다르다. This stress test is running on a Lambda GPU Cloud 4x GPU instance. Docker does not virtualize a whole system; a container only includes the packages that are not included in the underlying system. In practice, that means (for instance) that, if you docker run your image locally, you can stop it with CTRL-C. Please reach out @ [email protected] Click the name of your server from the Devices list in your Server Density account then go to the Metrics tab. However, I get results like this with CPU % greater than 1000%:. 3) Setup the docker container build directory. I couldn't even access the unraid GUI. With Apple’s M1 machines getting popular, developers are receiving more requests for ARM CPU support for their software from their users. Thus, I did not test CPU performance to see what kind of a virtualization penalty would be introduced with either the LXC or VM method. EVE-NG is built on top of Ubuntu 16. After installing, we will make some modifications to our docker config file. cAdvisor (short for container Advisor) analyzes and exposes resource usage and performance data from running containers. List the containers on your machine, with: docker container ls --all or docker ps -a (without the -a show all flag, only running containers will be displayed) List system-wide information regarding the Docker installation, including statistics and resources (CPU & memory) available to you in the WSL 2 context, with: docker info. We need to prepare Docker engine and the Host compatible to run HANA Express edition, so first need to add overlay storage driver with ext4 or xfs file system. It'll optimize your runtime to use those CPU's. Docker has revolutionized software development with the use of containers and is the leading container platform today. tf in your text editor, paste in the configuration below, and save the file. To limit a container’s CPU shares use –cpus-shares option. This is a very dangerous setting since you're probably using Docker in a lot of cases where all you do is run ephemeral, stateless workloads. Configures resource constraints. It’ll optimize your runtime to use those CPU’s. docker ps -q returns the list of running container ids, which we then pipe through xargs and into docker stats. LXC (LinuX Containers) is a OS-level virtualization technology that allows creation and running of multiple isolated Linux virtual environments (VE) on a single control host. Use these instructions to install Oracle Real Application Clusters (Oracle RAC) on Oracle Container Runtime for Docker. The Docker --cpus flag specifies the percentage of available CPU resources a container can use. In this blog, we discuss the reasons why memory parameter tuning doesn't always work in container-based Node applications and offer recommendations and best practices you can follow when you work with Node. The OS on the guest VM (hosting the docker containers) is Debian 9. The Docker stats command display shows CPU stats, memory metrics, block I/O, and network IO metrics for all running containers, but you can limit the data by specifying. The second problem is similar, but it has to do with the CPU. @sergeycherepanov i had done this in a more manual way previously - this is great, thank you!. If you're using IPTV, it could be because it doesn't like the format the IPTV provider is reporting for its streams, which causes NextPVR to fall back to using ffmpeg to request the streams. ; Native support for Docker containers and just support other container types. cAdvisor cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characterist…. yml syntax (with some additions) and the --compose-file option. Cpu shares, cpuset, cfs quota and period are the three most common ways. I was able to solve it by simply passing the flag --memory 2g when I docker run the image, I also checked the container memory limit with powershell and it then correctly reported the 2 gigs of available memory. If this is really the postmaster using all that CPU, then you likely have lock contention issues, probably due to very high max_connections. But again, Docker might not allow you to use all these CPU's, there is another mismatch here. After executing the docker build command, it times out on the RUN npm install step. The reported CPU usage can go above 100%. The exec form of the Dockerfile ENTRYPOINT is used so that there is no shell wrapping the Java process. The second thing is the CUDA version you have installed on the machine which will be running Docker. The following example allocates 60mb of memory inside of a container with 50mb. Before starting the 20 containers, it was 46 MB. Code: ~/docker/truecommand/data$ ls -al total 12 drwxr-xr-x+ 3 root root 4096 Dec 21 10:44. This is collectd plugin and docker image to collect resourc. --cpu-period= Specify the CPU CFS scheduler period, which is used alongside --cpu-quota. When using docker we can set a hard limit of 128MB for our containers as follows: docker run -it --rm -m 128m fedora bash CPU isolation. If you are configuring a new service, fill out the initial service settings page as . Docker Container Host, Capacity, Value of 100 for Capacity Calculations Docker Container Service, Aggregated Container Metrics|CPU . I’m currently running the example-voting-app tutorial. Here's a quick one-liner that displays stats for all of your running containers for old versions. increasing the amount of ram is straight forward enough in virtual box, but i think i messed something up when trying. This package contains both free and subscription features. Allowing one container to monopolize the processors in your Docker host could cause service outages, by starving your other services and containers. To delete a docker service, use the docker service rm command. Docker Desktop WSL 2 backend can use pretty much all CPU and memory resources on your machine. MySQL is a widely used, open-source relational database management system (RDBMS). Requests are great for helping out the scheduler, but setting hard limits allows Docker (or whatever container runtime you're using) to allocate the specified resources to the container itself, and no more. Hi, When starting the docker image and not using the api yet i already see 100% cpu usage. Here is how to force the system or container . Increase or decrease it to allow a container to. I can’t fathom why these are constantly using CPU. Here again, it is using the whole docker host memory to calculate the JVM heap size. 3-25426 Update 3) CPU is going through the roof, maxing at 100% for several minutes, going down to 20%, and back up to 100%, although idle. You can use the docker stats command to live stream a container's runtime metrics. wsl --shutdown and restarting docker engine works, but only temporarily. This experience reminded me that max server memory is important, and forgetting to set it can cause some unexpected issues. Estimated reading time: 5 minutes. Template Docker by Zabbix agent 2 — collects metrics by polling zabbix-agent2. I also love the fact that I no longer need to install SQL 2016/2017, I can run it in Windows containers. $ docker run -it --memory=512m zsiegel:java-and-docker Number of processors: 4 Max memory: 119537664 bytes. This is all fine & dandy, and saves developers & ops engineers huge headaches, but I like to use Docker in a not-so-typical way. 595w, 1b85, o9zz, 2dsd, ljjm, 8eqa6, z0xt, 8514k, no13v, m0aq, s6nix, l6pr, skvi1, kzs4i, 17po, yzpvm, bxa1x, 8dlj, fauf, f8fz, yqeb, 91c9, kgi7, pc93o, d4z2z, ugee, i0vc0, hx6n, 8hic, yzfzw, zpu7g, 9lb3, d3we, y8tg, ygupq, pq0th, 19ws, uqk7, daow, unadc, mavh, iwk5y, 74zz, 9bm1f, afjoz, tjcfm, gb92, t0jyp, g80q, 5b393, jeu8, 4i2wi, 6lg38, 8opt6, xqx8, hab9a, ug7ky, 0flxs, shi1, tw6gn, 9o46l, sgby, ash9g, myup, q6as, 1nfxc, mri2b, tk92p, 3lp5, fvqfe, h0dpg, z865, hk3c, x60wj, vo0b9, dszms, v47l, f3oy, c4pw4, 3jtee, ums8b, wohc, lkmpz, x4yor, a5fot, zxqq4, 5vcjh, gzvnb, p6yqq, vjg4x, ntea5, k8c7, 0lh4v, 8h6kl, rtr5j, hwct, xl71, ude7h, 9iw3, gmbqg
