Starting Nuxeo LTS 2023 with metrics enabled
metrics.enabled=true # prometheus metrics.prometheus.enabled=true metrics.prometheus.port=9090 #jmx metrics.jmx.enabled=true
will cause an error on startup
Exception in thread "prometheus-http-1-1" java.lang.NoClassDefFoundError: io/prometheus/client/SampleNameFilter at io.prometheus.client.exporter.HTTPServer$HTTPMetricHandler.handle(HTTPServer.java:98) at jdk.httpserver/com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:95) at jdk.httpserver/sun.net.httpserver.AuthFilter.doFilter(AuthFilter.java:82) at jdk.httpserver/com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:98) at jdk.httpserver/sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(ServerImpl.java:852) at jdk.httpserver/com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:95) at jdk.httpserver/sun.net.httpserver.ServerImpl$Exchange.run(ServerImpl.java:819) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833) Caused by: java.lang.ClassNotFoundException: io.prometheus.client.SampleNameFilter at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1412) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1220) ... 10 more
This is due to the fact that simpleclient-httpserver is in version 0.16.0 whereas simpleclient, which should contains io.prometheus.client.SampleNameFilter, is in version 0.6.0
An upgrade of the "simpleclient" lib in LTS 2023 would fix the issue.
Note that a mismatch is also present in LTS 2021 with simpleclient-httpserver 0.9.0 and simpleclient still in 0.6.0
