Monitoring with Graphite/Grafana

Post by supremepizza » Wed Jul 31, 2019 12:55 am

Has anyone figured out how to get stats out of QES to graphite? It seems the only official way to monitor is via SNMP, but I would much rather have the ability to output stats like QTS can.

I sort of figured out a hackey way to do this. I'm only sharing this in hopes someone like me that needs recorded stats other than from SNMP finds it useful.

DO THIS AT YOUR OWN RISK, The controller OS is not meant to be messed with by plebs like us and may make your system unreliable!!!.

You need to log into the cli via SSH, type 'xlogin' then enter the support password. If you email qnap support and ask for the password, they will be able to tell you.

I created a share on a pool named util, then downloaded the collectd freebsd port from here: http://pkg.freebsd.org/FreeBSD:11:amd64 ... .9.0_2.txz

https://freebsd.pkgs.org/11/freebsd-por ... 2.txz.html

The rootfs of the qnap controller is read-only, so all my configs and logs and such live on the util share I created. This means every time the controller is rebooted, I'm going to have to kick off the process from the cli.

I'm launching it from the share and specifying the conf file - example: /share/util/usr/local/sbin/collectd -C /share/util/usr/local/etc/collectd.conf
Here's a sample conf

Code: Select all

#
# Config file for collectd(1).
# Please read collectd.conf(5) for a list of options.
