Docker ULM
The Docker ULM App is a unified logs and metrics (ULM) app that utilizes data from Docker container logs, engine events, and container stats to monitor your Docker deployment.
The Sumo Logic App for Docker ULM is a unified logs and metrics app that allows you to monitor your Docker deployment. The preconfigured dashboards present information about container state and resource usage, including CPU, memory, block I/O, and network.
Log and metric types
Sumo’s Docker Logs source and Docker Stats source use the Docker Engine API to gather the following data from Docker:
- Docker container logs. Sumo’s Docker Logs source collects container logs. For information about the API Sumo uses to collect logs, see the https://docs.docker.com/engine/api/v1.37/#operation/ContainerLogs in Docker help.
- Docker engine events. Sumo’s Docker Log source collect Docker events. For information about Docker events, see https://docs.docker.com/engine/api/v1.37/#operation/SystemPing in Docker help.
- Docker container stats. Sumo’s Docker Stats source collects stats. For information about Docker stats, see https://docs.docker.com/engine/api/v1.37/#operation/ContainerStats in Docker help.
By default, you can monitor up to 40 Docker containers on a Docker host. If you want to monitor more than 40 containers on a given host you can configure a larger number in collector.properties, as described in Collect Logs and Metrics for Docker ULM. We don’t support monitoring more than 100 containers on a Docker host.
