I've installed Hyperic HQ to monitor Zimbra, but I can't get any usefull information...

I'm using Hyperic 4 and Zimbra 5. The agent detects Zimbra services (MTA, MySQL, LDAP, Jetty, etc), but doesn't send any metrics.

For MySQL service, I cannot get any information at all (service will be disabled in Hyperic), because I'm running Hyperic as hyperic user and cannot access the mysql server (even if I create a user for hyperic in MySQL)...

For Zimbra I onlye get metrics on CPU usage (always 0!) and memory usage (works fine).

Hyperic should provide much more metrics than this:
Zimbra - Confluence

Any experiences of Hyperic and Zimbra?
