Overview
Docker monitoring is a Gateway configuration file that enables monitoring of Docker installations through a set of samplers with customised Toolkit plug-in settings.
This can be monitored locally or remotely. If you set up the Docker installation locally, the Docker daemon and Netprobe will run on the same machine.
If you want to monitor it remotely, then the Docker daemon Netprobe will not run on the same machine.
Track the following key areas when using Docker monitoring:
| Key Area | Description |
|---|---|
| Status | Provides information about the containers running on the host, including their container ID, name, port information, and size. |
| Usage | Collects performance statistics about each container and returns each container’s individual CPU and Memory utilisation information, Net IO, Block IO Information, and the configured limits. |
Intended audience
This technical reference is intended for users who will be using Active Console to monitor data from Docker. If you are setting up the integration for the first time, see Docker Monitoring User Guide.
