Hi Everyone
Does anyone here uses cassandra-exporter: Release v0.9.12 ·
instaclustr/cassandra-exporter · GitHub
<https://github.com/instaclustr/cassandra-exporter/releases/tag/v0.9.12> using
embedded, agent jar?
I'm running into an issue post exporter deployment; When GET call is fired
towards the embedded agent socket/port, the call is stuck and from the
cassandra logs it can be seen that it tries to call a getBroadcastAddress()
method from cassandra, which isnt found:
WARN [prometheus-netty-pool-0] 2024-03-05 17:50:59,016
DefaultChannelPipeline.java:1152 - An exceptionCaught() event was fired,
and it reached at the tail of the pipeline. It usually means the last
handler in the pipeline did not handle the exception.
*java.lang.NoSuchMethodError: 'java.net.InetAddress
org.apache.cassandra.utils.FBUtilities.getBroadcastAddress()'*

This most probably suggests incompatibility between the embedded agent and
cassandra.
The standalone agent 0.9.12 works fine, though performance wise its ~50X
slower.
Has anyone come across a similar issue or got the embedded jar to work?
What other alternatives are there for Cassandra v4 metric exposure with
similar performance/overhead as the embedded one:

Thanks/Anton
