We've done a bunch of work on collectd collectors. It has the benefit of being lightweight and low-impact, but isn't as inherently flexible as nad. https://github.com/Coraid/coraid-collectd <https://github.com/Coraid/coraid-collectd> > > We use nad everywhere: https://github.com/circonus-labs/nad > <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...

The upstream (collectd.org <http://collectd.org/>) collectd collectors are pretty generic and lowest-common denominator. To get details like mpstat/vmstat we added new collectors, see above link. -- richard > > Thanks in advance. > > - cks > _______________________________________________ > OmniOS-discuss mailing list > OmniOS-discuss@lists.omniti.com <mailto:OmniOS-discuss@lists.omniti.com> > http://lists.omniti.com/mailman/listinfo/omnios-discuss > <http://lists.omniti.com/mailman/listinfo/omnios-discuss> > > > > -- > Theo Schlossnagle > > http://omniti.com/is/theo-schlossnagle > <http://omniti.com/is/theo-schlossnagle>_______________________________________________ > OmniOS-discuss mailing list > OmniOS-discuss@lists.omniti.com > http://lists.omniti.com/mailman/listinfo/omnios-discuss
