lemmy-synapse is a light-weight observability and monitoring stack for Lemmy servers.

Using Prometheus and Grafana, it allows the admins to visualise and query the stats of their instance. v1.0.0 comes out of the box with 3 detailed dashboards:

• Host stats (CPU, RAM, disk, network, ...)
• PostgreSQL stats (connections, locks, transations, queries, ...)
• Docker stats (container CPU, RAM, disk, network, OOM signals, ...)

It runs as Docker compose cluster alongside the Lemmy cluster and does not require any changes to it in most cases. Uninstalling lemmy-synapse is as easy as tearing down its cluster and deleting its installation directory.
