The project is using micrometer and it also opens JMX on port 8686
; they give you a lot of information about what is going on under the hood, e.g.:
Metrics endpoint: /actuator/metrics
Heap usage: /actuator/metrics/jvm.memory.used?tag=area:heap
Direct byte buffers (Off Heap): /actuator/metrics/jvm.buffer.memory.used?tag=id:direct
CPU usage: /actuator/metrics/process.cpu.usage
Number of CPU cores: /actuator/metrics/system.cpu.count
Daemon thread count: /actuator/metrics/jvm.threads.daemon
Loaded Classes: /actuator/metrics/jvm.classes.loaded
Container (Tomcat) Threads: /actuator/metrics/tomcat.threads.current
docker run -it -p 8080:8080 -p 8686:8686 -v logs:/app/logs jonatanivanov/resourceater:tag
You need a cluster first, e.g.: kind create cluster
skaffold dev --port-forward
or
skaffold run --port-forward
