Hello,

I have a PCP setup where pmcd runs on multiple hosts and there is a server where pmlogger collects metrics from these hosts.

I understand how I can use pmie to analyze logs or live data from one or a few hosts. What are my options if I have a large number of hosts, say 1,000 or 10,000 hosts. What kind of setup would I need to do so I detect if any of my 1,000 or 10,000 hosts has, for example, "high disk i/o"?

Thank you!
Rares
