Compatiblity with cassandra 5.0.3

[ut0mt8]

Despite trying various combination of cassandra-exporter arround the web I still got following exceptions: (0.9.14)

Feb 25 14:59:16 ip-10-0-5-136.eu-west-1.compute.internal cassandra[27283]: [cassandra-exporter-harvester-defer-0] WARN com.zegelin.cassandra.exporter.Harvester - Failed to register collector for MBean org.apache.cassandra.metrics:type=Connection,scope=10.0.5.6_7000,name=GossipMessageDroppedTasks.

Does anyone have a compiled working version somewhere for recent C* ?

OK so for the record it's working with tweaks :

1. take the latest snapshot and patch as of itskarlsson@b4de305

2. maven package it skipping test

3. add netty-codec-http-4.1.96.Final.jar in cassandra lib

4. add the good lines in cassandra-env.sh

JVM_OPTS="$JVM_OPTS --add-opens java.management/com.sun.jmx.interceptor=ALL-UNNAMED"
JVM_OPTS="$JVM_OPTS --add-opens java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED"
JVM_OPTS="$JVM_OPTS -javaagent:$CASSANDRA_HOME/lib/cassandra-exporter-agent-0.9.15-SNAPSHOT.jar"

Is there plan to provide Cassandra 5 metrics support ?

this repo seems pretty unmaintened. That said see my comments it's possible but you have to do it yourself

Not an ideal solution, but I got the exporter working by including the netty jars that come with Cassandra 4.1.x in the $CASSANDRA_HOME/lib directory:

• netty-all-4.1.58.Final.jar
• netty-tcnative-boringssl-static-2.0.36.Final.jar

If you need a temp fix, this will work. They are listed as dependencies in the project. Ideal solution is to build with the correct dependencies.

does it also adds new metrics in Cassandra 5 to be available for Prometheus scraping.

This works for cassandra v5.0.2
