collectd-nfsstat-freebsd

A small script to gather counters from the nffstat command (FreeBSD version) to send to collectd.

This uses the -e flag to gather stats, and has not been tested against NFS v3.

Installation

git clone https://github.com/smuth4/collectd-nfsstat-freebsd
cd collectd-nfsstat-freebsd
sudo mkdir -p /usr/local/etc/collectd.d/
sudo cp nfsstash.sh /usr/local/etc/collectd.d/ && sudo chmod +x /usr/local/etc/collectd.d/nfsstash.sh

Configuration

Edit the script and adjust the default INTERVAL, or change CLIENT_STATS or SERVER_STATS to false to gather only client or only server stats respectively.

Somewhere in collectd's configuration file, add the following:

LoadPlugin exec
<Plugin exec>
   Exec nobody "/usr/local/etc/collectd.d/nfsstat.sh"
</Plugin>

Notes

Regarding the datatype, having gauge as the datatype is ugly if it gets exported somewhere else, but I use Graphite rules to strip it out. To change it natively in collectd, edit your types.db to have a custom entry, and change the CLIENT_DATATYPE and SERVER_DATATYPE to use that entry.
