Dave,

We have a known bug on another system that is causing this problem. We have yet to figure out the issue. You should be able to monitor this many devices from a single server (what are the specs of the box?) You can look in $ZENHOME/log/zenperfsnmp.log to see what your cycle time is.

I am currently monitoring about 150 devices (about 60 servers and 90
switches), and I have noticed that on some devices I get gaps in the RRD
graphs.

I am concerned about this because I am not sure if it is an indicator
that the system is too busy to poll that device. I don't get any alerts
about the device being down, but there are gaps in a lot of the graphs
of the devices.  Should I be looking at perhaps breaking my monitoring
server into multiple stations? Also, does ZenOSS support clustering or something similar? Can I have multiple 'sensor' stations reporting to a
central server that I monitor everything on?

Thanks in advance for any advice!
