This article focuses on "how to monitor the service process in the docker container". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to monitor the service process in the docker container.

The disadvantage of docker is that encapsulating code in a set of containers can lead to a lack of visibility, turning the container into a black box and making developers almost invisible to the way the container works. In order to allocate the resources that can be used by each container more accurately, we want to get information about the resources used by the container in real time.

Whether it is the traditional basic component monitoring or application performance monitoring, it is difficult to effectively monitor Docker. Introduce the existing Docker-related monitoring App and services, including simple open source tools, here are a few for reference.

CAdvisor

Google's container introspection solution is cAdvisor, a utility packaged in a Docker container that collects, aggregates, processes, and exports information about running containers. Through it, you can see CPU utilization, memory utilization, network throughput, and disk space utilization.

You can then learn more about its usage by clicking on the Docker Containers link at the top of the page and selecting a container. CAdvisor is easy to deploy and use, but it can only monitor containers running on the same host, which is not very useful for multi-node deployment.

Cloud Insight

Among the several monitoring Docker container service platforms listed, this is a domestic product. Cloud Insight supports the monitoring of a variety of operating systems, cloud hosts, databases and middleware. The principle is that Metric is collected and processed in platform service dashboards and custom dashboards, data aggregation and grouping are calculated, and various display forms such as graphs and bar charts are provided. The advantage is that the monitoring indicators are very comprehensive and easy to use.

Scout

Scout is a monitoring service, not a stand-alone open source project. It has a large number of plug-ins that absorb other data about deployment in addition to Docker information. Therefore, Scout is an one-stop monitoring system, and there is no need to install different monitoring systems for various resources of the system.

One disadvantage of Scout is that it does not display detailed information about individual containers on each host. In addition, each monitored host costs 10 US dollars, which is also a consideration in whether to choose Scout as the monitoring service. If you run a very large deployment with multiple hosts, the cost will be relatively high.

Sematext

Sematext is also a paid monitoring solution, with a planned charge of 3.50 cents per hour. Docker monitoring is also supported, including monitoring container-level events (stop, start, etc.) and managing logs generated by the container.

At this point, I believe you have a deeper understanding of "how to monitor the service process in the docker container". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
