<body>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>This brings the ability to monitor ARC and pool information,
with each pool having its own separate set of graphs.</p>
<p>The ARC graphing is as below.</p>
<ul>
<li>ARC size in bytes</li>
<li>ARC size, percent of max size</li>
<li>ARC size breakdown</li>
<li>ARC efficiency</li>
<li>ARC cache hits by list</li>
<li>ARC cache hits by type</li>
<li>ARC cache misses by type</li>
<li>ARC cache hits</li>
<li>ARC cache misses</li>
<li>ARC misc (deleted, skips, and recycle misses)</li>
</ul>
<p>The pool tracking is comparatively much simpler, using the
output from <tt>zpool list</tt>.</p>
<ul>
<li>Pool Space</li>
<li>Pool Capacity</li>
<li>Pool Fragmentation</li>
</ul>

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