Put zfs.py into a directory (e.g. /opt/collectd-plugins). Load with, e.g.:

LoadPlugin python
<Plugin "python">
  ModulePath "/opt/collectd-plugins"
  Import "zfs"
</Plugin>

Load zfs.json and zfs_arc.json into Grafana. They assume the data is saved in a Grafana dataset named collectd.

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

Enable persistent storage for the systemd journal log

Overview

The assumed default setting in /etc/systemd/journald.conf is Storage=auto which implies that systemd journaling will only persist the journal if the expected storage location is available. Otherwise, the journal data is stored in memory and lost between reboots. On Ubuntu 16.04, /var/log/journal does not exist by default. Create it to keep and query events from previous boots.

Considerations:

• Syslog still provides the persistant log records for Ubuntu 16.04, so enabling persistant systemd journal logging does cause a level of duplicaiton.
• There are sane defaults:
