Andrew Jorgensen commented on CASSANDRA-11677:
----------------------------------------------
Not great, much slower than the jolokia 1.2.3 client. So i think there must
have been a performance degradation in jolokia. I have a ticket open on the
jolokia github repository to talk about the issue. We ended up being able to
work around the issue by upgrading to the master version of the diamond jolokia
collector and kept the updated jolokia agent which seems to have resolved to
issue.
Thanks so much for your help.
> Incredibly slow jolokia response times
> --------------------------------------

> Key: CASSANDRA-11677
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11677
> Project: Cassandra
> Issue Type: Bug
> Reporter: Andrew Jorgensen
>
> I am seeing some very slow jolokia request times on my Cassandra 3.0 cluster.
> Specifically when running the following:
> {code}
> curl 127.0.0.1:8778/jolokia/list
> {code}
> on a slightly loaded cluster I am seeing request times around 30-40 seconds
> and on a more heavily loaded cluster I am seeing request times in the 2
> minute mark. We are currently using jolokia 1.3.2 and v4 of the diamond
> collector. I also have a Cassandra 1.1 cluster that has the same load and
> number of nodes and running the same curl command comes back in about 1
> second.
> Is there anything I can do to help diagnose this issue to see what is causing
> the slowdown or has anyone else experience this?
