Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Prometheus JMX Exporter for Java17
6 projects | reddit.com/r/PrometheusMonitoring | 9 May 2023
After doing some research it appears this class references internal packages and therefore "makes it unusable for modern Java apps" (https://github.com/prometheus/client_java/issues/533 , https://github.com/open-telemetry/opentelemetry-java/issues/4192)
Python in SRE?

For monitoring: If you want to go the open source route, the open telemetry ecosystem is booming. You could use the open telemetry java agent along with their collector, and then use Elastic APM, which could give you a good starting point. Here is a small example project I found on github that was fun to play around with and explore the capabilities of a setup like this: https://github.com/riferrei/otel-with-apache-pulsar
Best performance monitoring tools?

OpenTelemetry and Java Flight Recorder (JFR) cover most bases. Use the OpenTelemetry Java agent if you want auto-instrumentation or just the APIs if you want to do your own instrumentation.
