This article to share with you is about how to understand a variety of Docker monitoring solutions, Xiaobian feel quite practical, so share for everyone to learn, I hope you can read this article after some gains, not much to say, follow Xiaobian to see it.

We've covered ps/top/stats, Sysdig, Weave Scope, cAdvisor, and Prometheus container monitoring tools and solutions, so it's time to compare them. Here are five ways to compare them.

ease of deployment

ps/top/stats is easily the easiest to use, they are Docker's own subcommands that can be used to quickly understand the state of containers anytime, anywhere. The rest can also be run as containers, which are generally not complicated. Relatively speaking, Prometheus involves more components, the number of containers needed to run the whole solution is also more, and the deployment and management are slightly larger.

data detail

ps/top/stats and cAdvisor monitor basic resource usage of containers, while Sysdig, Weave Scope and Prometheus provide richer data.

Multiple Host Monitoring

Weave Scope and Prometheus can monitor entire clusters, while the rest of the tools only provide monitoring capabilities for individual hosts.

alert function

Only Prometheus has native alerts.

Monitoring non-container resources

Sysdig, Weave Scope and cAdvisor can monitor the status of the Host operating system, Prometheus can support application-level monitoring through Exporter, such as monitoring ceph, haproxy, etc.

The results of the comparison of the four aspects are shown in the table below.

some suggestions

Docker ps/top/stats is best suited to quickly understand container health and determine if further analysis and troubleshooting is needed.

Sysdig provides a wealth of analysis and mining capabilities and is the artifact of Troubleshooting.

cAdvisor is generally not used alone, but as a data collector for other monitoring tools, such as Prometheus.

Weave Scope's smooth and simple control interface is its biggest highlight, and supports direct execution of commands on the Web interface.

Prometheus 'data model and architecture dictate that its possibilities are almost limitless. Prometheus and Weave Scope are excellent container monitoring solutions. In addition, Prometheus can monitor other applications and systems, which is more comprehensive and comprehensive.

The choice of monitoring system is not a single choice question. It should be combined according to the needs and actual conditions, and the advantages complement each other. In addition to the five tools and solutions described here, there are many options in the monitoring field that can also be considered.

The above is how to understand various Docker monitoring solutions, Xiaobian believes that some knowledge points may be seen or used in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
