I am using opscenter 3.1.1 and just enabled JMX username/password authentication on my Cassandra cluster. I think I've updated all my opscenter configs correctly to force the agents to use JMX auth, but it is not working.

I've updated the config under /etc/opscenter/Clusters/[cluster-name].conf with the following jmx properties

    [jmx]
    username=username
    password=password
    port=7199

I then restarted opscenter and opscenter agents, but see the following error in the opscenter agent logs:

    DEBUG [Thread-10] 2013-11-15 10:07:28,461 Adding JMX connector to pool (127.0.0.1:7199)

A few lines above this stacktrace, I do see a line saying the agent is retrieving the latest config from opscenter:

    INFO [StompConnection receiver] 2013-11-15 10:07:18,298 Got new config from OpsCenter:

But the only jmx-related property in the data is :jmx_port 7199.

This seems to be a bug in 3.2.2 (http://mail-archives.apache.org/mod_mbox/cassandra-user/201310.mbox/%3CCALHkrw_xjJBy5k-7vCc3NezLy17HLY_HPDCFptG74RqiivcgBg@mail.gmail.com%3E), but I see no indication that it is a bug in 3.1.1 or that it has been fixed in 4.0.

Any ideas on how to fix this?

The bug mentioned in that mailing list thread affects 3.1.1 as well, and has been fixed in 4.0.0. We'll get a mention of that added to the release notes.

For future reference, the internal ticket number is OPSC-2136. And we strip any authentication information from the config logging you mentioned.
