Hi!, I've been running Observium on SLES11 for almost a year. This was on a 8 vCPU + 2GB RAM VMware guest with a 30GB RRD footprint.

After adding about 320 new hosts (all of them, network gear) the RRD database went to 130GB and the little machine got peaks of 3k IOPS. The I/O wait was rather hi and the machine would suddently stop responding (Hypervisor stats showed 0% CPU usage).

So, I've migrated the installation to a physical machine running Solaris 11 (I know, it's not supported) and without any tunning (mysql/zfs are candidates) I'm seeing polling of 41 devices in about an hour. Is this usual/expected?

./poller.php 0/24 February 13, 2013, 18:27 - 27 devices polled in 4048. secs

./poller.php 7/24 February 13, 2013, 18:27 - 27 devices polled in 4075. secs

./poller.php 0/24 February 13, 2013, 18:28 - 27 devices polled in 3803. secs

./poller.php 22/24 February 13, 2013, 18:28 - 27 devices polled in 4404. secs

./poller.php 3/24 February 13, 2013, 18:28 - 28 devices polled in 4417. secs

IOPS climbed to 5k, comments?
