Working monitoring solution for Docker Containers and Swarm?

Question

I'm looking for the monitoring solution for the web application, deployed as a Swarm of Docker containers spread through 7-10 VMs. High level requirements are:

• Configurable Web and REST interface to performance dashboard
• General performance metrics on VM levels (CPU/Memory/IO)
• Alerts when containers and/or VMs are going offline/restart
• Possibility to drill down into containers process activity when needed
• Host OS are CoreOS and Ubuntu

Any recommendations/best practices here?

NOTE: external Kibana installation is being used to collect application logs from Logstash agents deployed on VMs.

Answer 1

Based on your requirements, it sounds like Sematext Docker Agent would be a good fit. It runs as a tiny container on each Docker host and collects all host+containers metrics, events, and logs. It can parse logs, route them, blacklist/whitelist them, has container auto-discovery, and so on. In the end logs end up in Logsene and metrics and events end up in SPM, which gives you a single pane of glass sort of view into all your Docker ops bits, with alerting, anomaly detection, correlation, and so on.
