------------------------------------------------------------------------
-So this appears to actually be a jolokia problem. I was able to downgrade to
jolokia 1.2.3 and now metrics are coming in fine and the requests to that
endpoint are down to only a couple seconds. I am not sure what changed between
jolokia 1.2.3 and 1.3.3 but it appears to be causing an issue.-

> 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?
