Expose metrics for Prometheus Monitoring Framework? #1190
Description
Activity
Hi @goettl79. That's certainly a great suggestion. Gitblit doesn't currently track many/any stats now. It could be instrumented for metrics collection, of course. Is this something you'd be interested in contributing? I have had success using DropWizard Metrics to report to monitoring systems in other projects. Do you know if there is a Prometheus adapter for Metrics? Or would it require a one-off integration with Prometheus?
I would be interested in contributing this feature, probably following the approach taken here: prometheus/client_java#101.
Didn't know that gitblit is dropwizard service. Btw. Dropwizward Metrics do not export gitblit specific metrics, but only general service metrics to my knowledge.

It is not, you misunderstood.
Ah, ok. Then I'll see how far I get using the standard prometheus java client. Will add a pull request as soon as possible.
I implemented a first version of the metrics in pull request #1230 . @gitblit @fzs you can inspect the metrics on https://localhost:8443/prometheus/.
Next to default metrics for the jvm and log4j I implemented two metrics for git_garbage_collection and ldap sync time. ldap sync time is only visible when ldap is configured.
I wonder if this would also be possible through OpenTelemetry. I would like to have some adoption measurements and was planning to use OTeL for that.
Having two separate observability systems seems overkill. On the other hand, Prometheus seems to come with many default libraries so not much needs to be done.
It might still be nice to have system that allows for push and pull exporters, and OTeL has a Prometheus exporter. But that is classified as experimental.
Hi,
Anybody interested to expose gitblit metrics for the prometheus framework (prometheus.io). Would be a quick win I think. At least some basic metrics would be fine. E.g. Garbage Collections, Pushes / Pulls / Clone durations and so on...
