grafana-truenas-install

Manual installation of Grafana and InfluxDB in a jail on TrueNAS CORE. This is aiming to provide a complete production ready setup.

Prerequisites

• create a VNET jail on TrueNAS CORE
• make sure network settings are correct and the jail can connect to the Internet
• Log in to the jail as root either directly via SSH or via iocage console <jail> from the TrueNAS host

Installation

Install required packages

Configure pkg to use "latest" instead of "quarterly" repository

mkdir -p /usr/local/etc/pkg/repos
echo 'FreeBSD: { url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest" }' >/usr/local/etc/pkg/repos/FreeBSD.conf
pkg upgrade -y
pkg autoremove -y

Install packages

pkg install influxdb grafana

Configure, enable and start InfluxDB

Create influxd configuration file

Complete separate config file

Create /usr/local/etc/influxd.conf with this content:

[meta]
  dir = "/var/db/influxdb/meta"

[data]
  dir = "/var/db/influxdb/data"
  wal-dir = "/var/db/influxdb/wal"

[[graphite]]
  enabled = true
  database = "graphite"
  retention-policy = ""
  bind-address = ":2003"
  protocol = "tcp"
  consistency-level = "one"

  separator = "."

  templates = [
    "servers.* .hostname.resource.instance.measurement*",
  ]

This configures influxd with a single connector using the "Graphite plaintext protocol". TrueNAS CORE and e.g. OPNsense can readily send metrics to influxd using this protocol.

Enable and start the influxd server

sysrc influxd_enable=YES
service influxd start
