Hi, Chet:
Thanks for the quick response.

I see. So I would:
o Change my base alert so it doesn't fire when event class is
"/Status/Ping".
o Add a second alert (delay == 0) that fires when event class is
"/Status/Ping" and device class is *not* "/Server/Windows".
o Add a third alert (delay == 300) that fires when event class is
"/Status/Ping" and device class is "/Server/Windows".
Does that look right? How do the clear events work with delay? I
assume they are sent immediately?
Could the same effect be had by adding a filter on "count" (say,
"count > 4")? I guess then if I change the ping frequency I also
change my alert behaviour, which isn't desirable. Also, how would the
clear events work in this case (since count for them would never
be > 4)?
This approach (updating the alerts) seems a bit awkward, but it looks
like it will work (thanks again!). If I wanted to enhance
/Status/Ping with this behaviour, where would I start? Should I take
this to zenoss-dev?

I would like to do this. However, when I go to a device's PerfConf
tab, I see the data sources listed, but they aren't hyperlinks. For
instance, on my Windows box, the following data sources are listed:
cpuPercentProcessorTime
memoryAvailableKBytes
memoryPagesPerSec
sysUpTime
However, I can't click on any of them. I'm using Zenoss 1.1.1.
