NeophyteFYI I'm working right now on a DataSource which will use SNMP for collecting process memory, CPU, etc. from Linux hosts, instead of calling "ps" via SSH which is what Stuart's does.
I am hoping to make a viable version which will indeed create Instances for only the "Top X" based on memory usage, which I'm hoping is consistent enough that if "X" is at least 15 or 20 (number of Instances to be created) then with AD running every 15 minutes there won't be so much turnover on the Instances as to be useless. (I'm starting off with the PID as the Wildvalue.)
If that doesn't work I might try making the Wildvalue out of the process name in the hopes that there will be some consistency there instead.
In general trying to capture the "Top X" utilization for dynamic things like processes is a balancing act between collecting metrics for everything vs. not enough.
I'm hoping that the SNMP Collect (batch script) won't be too hard-hitting on the device or Collector, because it ought to be just 3 SNMP walks total per collect - similar to the LM Core DS "LinuxNewProcesses" locator PMEZLA (except that one is Script not Batchscript)
