LibreNMS is an autodiscovering PHP/MySQL/SNMP-based network + monitoring solution which includes support for a wide range of + network hardware and operating systems, including Cisco, + Linux, &os;, Juniper, Brocade, Foundry, HP and many more.

+ +

Among other things, it can monitor applications and other + functionality running on a server via SNMP extensions. This + has been the area of focus for my present work.

+ +

ZFS support has been committed towards the end of December, + which was too late to make the December release, but it will + be in the January release.

+ +

This brings the ability to monitor ARC and pool information, + with each pool having its own separate set of graphs.

+ +

The ARC graphing is as below.

+ +

ARC size in bytes
ARC size, percent of max size
ARC size breakdown
ARC efficiency
ARC cache hits by list
ARC cache hits by type
ARC cache misses by type
ARC cache hits
ARC cache misses
ARC misc (deleted, skips, and recycle misses)

+ +

The pool tracking is comparatively much simpler, using the + output from zpool list.

+ +

Pool Space
Pool Capacity
Pool Fragmentation

+ + + + Suggestions are needed for additional statistics or other + information to monitor, whether &os;-specific or + otherwise. + +
