use version: 0.16.0

YANGJINJUE commented 7 months ago

use version: 0.16.0。jdk21. The presence of -1.0 in the expression jvm_memory_bytes_max{area="nonheap",} -1.0. why?

dhoard commented 7 months ago

@YANGJINJUE 0.16.0 shipped with the Prometheus client_java 0.11.0 library, which may have introduced the change.

I suggest you upgrade to the latest version 0.20.0 and adjust your dashboards.

We are also using 0.20.0 and it doesn't work with Java 21. There is no update of this issue since one month. Are you planing to fix it?

@YANGJINJUE 

Caused by: java.lang.NoSuchMethodError: 'io.prometheus.jmx.shaded.io.prometheus.client.Collector io.prometheus.jmx.BuildInfoCollector.register()'

typically happens if you have multiple versions of the jar somewhere in your classpath. The JVM is loading classes from different jars that mismatched/out of sync.

dhoard commented 6 months ago

@aestebangarcianavas can please elaborate? The code has been tested and works on...

For those confused by this: the Prometeus client_java library changed the name of the metrics from its 0.16 version to 1.0 version: https://github.com/prometheus/client_java/blob/main/docs/content/migration/simpleclient.md#jvm-metrics. You can consult the list of the changed names in the link above.
