Ok, This is related to the Heartbeat Post
(http://forums.zenoss.com/viewtopic.php?t=8292&highlight=), but I thought it
was significant to have its own string.
Ok, my zenoss sytsem is real slow, and it shouldn't be. Its a fresh 2.3 install
on Centos 5.1 (x32). Its on a XenSouce VM, and the VM has 2GB of ram, and
plenty of disk IO speed. (6 drive SAS raid) at this point there is no other VMs
running other then the Zenoss one.
I get a top (see below) with a real bad number for %wa,
I shut down the zenoss stack with "service zenoss-stack stop" and I get a
zenoss service left running, with still a bad %wa.
The service is:
/data/python/bin/.python.bin /data/zenoss/Products/ZenEvents/zensyslog.py
--configfile /data/zenoss/etc/zensyslog.conf --cycle --daemon
--useFileDescriptor=6
If I kill zensyslogd, my performace returns (but hard to tell with zenoss,
since the stack isnt running anymore.
Here is the top info:
