I’ll demonstrate on a Ubuntu 16.04 platform, but ctop can be installed on nearly any Linux distribution. The tool is easy to install, and even easier to use. Although it may not offer a massive amount of features, it does the job and does it well. Ctop even allows you to filter what you’re viewing, and gives you an expanded view of a selected container. With this app, you can get a quick overview of your containers, their names, IDs, and how much CPU, Memory, and Network Rx/Tx data. That’s right, one of the best means of monitoring your containers is an open source tool, found on Github, called ctop. However, do you know how well those containers are performing? If you’re familiar with Linux, you might wish there were an top/htop app geared specifically for containers. Chances are you’ve already done so and have numerous containers running on your network. If Docker is your container service of choice, you know how easy it is to create and deploy containers. Jack Wallen shows you how to install, and use ctop for quick and easy container monitoring on a Linux Docker server. Nginx, stylized as NGINX, nginx or NginX, is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.How to monitor your Docker containers with ctop PHP-FPM maintains pools (workers that can respond to PHP requests). Based on number of monitors installer prepares several instances of firefox agents (rbtmX) and its corresponding virtual screens (rbtmX-Xvfb). This is the "virtual screen" for the old Firefox check agent (rbtm). Xvfb or X virtual framebuffer is a display server implementing the X11 display server protocol. Redis is used for storing the check status and result and also as a queue for incoming checks. The redis-server command is a command line to launch a Redis server. Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker. In 10.7, it will be replaced with the new fpm agent (see below) The old full page monitor agent written in python and based on webkit. The Result broker support sending HTTP callbacks, but could be extended to support multiple callback protocols. This is only needed when the client provided a ?callback URL when requesting a check, something that the Scheduler currently does not do. The Result Broker is a component in the SmartPoP that is responsible for sending asynchronous check results back to the client callbacks. It will also keep track of expiry times (again via Redis), and purge the items that have expired. ![]() The Assets Manager will collect and persist them on disk. The Check agents can post assets to the Asset Manager via Redis. Next to a set of performance metrics, each check can output check detail objects. New agents (like webdriver) manage the asset storage themselves. It is also used for old agent only that cannot communicate with redis directly. The final component of the SmartPoP is the Assets Manager, which is responsible of storing Check Results and assets, and managing their lifetime. The HTTP Broker uses a set of empirically determined timeouts that should work well with the timeouts configured in the Check Agents, the SmartAPI and the Scheduler be careful when changing these. The function of the HTTP Broker is to listen on the Redis queue for the chosen agent, call the agent synchronously over HTTP, and push back the result into the Result Queue in Redis for the API to process. The HTTP Broker is used to communicate with historic Check Agents that communicate over HTTP themselves, instead of listen on a queue in Redis. The monitor checks are sent by the scheduler (running on ASM core servers) through this secure channel as a proxy to the API (see below)Īccepts check requests through the Tunnel Client, forwards them, maintains status.ĪPI goes through http broker and connects to PHP/CGI checkers. It is creating a connection between tunnel server and the OPMS. One instance is running only (using threads for concurrency) It prepares and runs the checks using selenoid (see selenoid-docker service below). This is the java agent that is responsible for webdriver monitor checks. ![]() This checks if the linux Xvfb daemon is running. the name is different on each OPMS) and checks the memory consumption is below 90% This service is named by the hostname (i.e. May we know which service is responsible for what ? If we run monit summary, it lists multiple services.
