Monitoring

This section describe how to setup a Grafana instance on one of the hosts in order to have a dashboard to monitor the machines. This strategy is a work in progress and does not implement any form of security. Use at your own risk

This strategy uses 3 components:

  • Promtail to collect the logs from the hosts (installed on every machine).
  • Loki to collect the logs on the main host.
  • Grafana to create the dashboard.

Prerequisites

$ brew install colima docker docker-compose
$ colima start

Configuration

  • Download the monitoring folder from this repo to the machine.

    $ scp -r monitoring admin@<HOST_IP>:grafana

  • Replace the HOST_URL and the MACHINE_NAME in promtail's configuration files.

  • Replace the HOST_URL in the docker-compose.yaml

Start the Containers

On the remote machine, install the service and launch it.

$ sudo chown root:wheel launch.sh
$ sudo cp com.mirego.ekiden-monitoring.plist /Library/LaunchDaemons
$ sudo launchctl load -w /Library/LaunchDaemons/com.mirego.ekiden-monitoring.plist

Post-Launch Configuration

  • Optionally import the pre-built dashboard in the grafana folder
