I just installed Orion 9.1 & APM 2.0 on a test server & have it monitoring some servers. After setting up 2 WMI counters (DiskWritesPersec & DiskReadsPersec) for a server, I'm seeing negative values in the MIN/MAX Average Statistic Data charts. The baseline is approx -30 with dips & spikes from that position.
Is this normal? If so, I'd appreciate it if someone could explain what I'm missing as I haven't done much with WMI counters before.
Thanks,
Jody
