[OmniOS-discuss] What do people use for basic system monitoring?

[Theo Schlossnagle]

Given that several of the original core OmniOS team work for Circonus, I'd
say the answer from this side would be pretty biased.

Collectd works okay, but certainly isn't my preference as the polling
interval can't easily modified on-demand during troubleshooting.

We use nad everywhere: https://github.com/circonus-labs/nad  It exposes
systems telemetry in JSON over HTTP and has some really nice features like
exposing histograms of syscall latencies and/or disk I/O latencies allowing
you to track the latency of every individual I/O against every spindle --
nice for understanding workload changes and disk behavior issues.

As it is JSON data, it should trivial to pump it into just about any
metrics systems... Circonus is free for up to 500 metrics:
