Monitoring, logging, metrics? #144

Open groldan opened 2 years ago

Vanilla GeoServer has the Monitoring extension

I don't know much about it, but at a first glance it looks like we could leverage standard cloud-native approaches to monitoring, logging, and metrics (e.g. Sentry, Promotheus, etc)?

At Camptocamp in the geOrchestra team we are mainly using an external Collectd which gathers metrics from the JVMs using a JMX endpoint, and exposes them later on as a Prometheus exporter (see https://collectd.org/wiki/index.php/Plugin:Write_Prometheus). Jetty comes with a convenient module which exposes some interesting metrics (http responses per status code, that you can derive to get a rate, ...) and adding extra ones is pretty easy using the dropwizard java library.

There are some other strategies based on JMX though, I think that our sysadmin are using a Java agent that acts as a prometheus exporter, so basically doing the same thing as described previously, but bypassing the collectd step.

Maybe spring boot / cloud offers a better approach than the previously mentioned ones, like a prometheus endpoint.
