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
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.

Everything you need to know about OpenTelemetry Java auto-instrumentation 👨🏽💻
opentelemetry-java - contains components for manual instrumentation as well as the API and SDK.

Migrating a Spring Boot application to Quarkus
Using the Async Profiler we were able to build flamegraphs for the first and second queries to picture the differences in path length of the two transactions execution.

Why would a Java prime sieve run at only half its speed _some_ of the times?
Also, running it under a profiler (I recommend async-profiler[1]) should give you a good idea of where the slowdown occurs which might help you pin it down further.

Rust Option 30x more efficient to return than Java Optional
async-profiler is really great at analyzing allocations, give it a shot!
