telegraf-edgeos

A lightweight Telegraf distribution customized for Ubiquiti's EdgeOS.

What is so cool here?

This Telegraf is crosscompiled for mips and mipsel. To reduce the size only essential and basic networking related internal plugins are part of the packaged binary. The result is a ~ 18 MB binary file instead of ~ 210 MB for a full featured Telegraf. So it should fit on every EdgeRouter.

edgeos.sh

To collect metrics that are availiable on EdgeOS but not collected via an internal module the package contains an additional plugin. You find it at /usr/lib/telegraf/edgeos.sh. It works with different parameters:

--firmware checks Ubnt's servers for EdgeOS updates and returns the result

--interfaces returns more details about a network interface like description, up/down-status and negotiated speed

--power prints power stats, like show hardware power

--temperature prints temperature stats, like show hardware temperature

Example:

edgeos_firmware running="v2.0.9-hotfix.2",availiable="v2.0.9-hotfix.2",upgrade=0,model="EdgeRouter 12",serial="ABC123456"

...

edgeos_interface,interface=eth4,type=ethernet alias="Server A",state=0,speed=1000
edgeos_interface,interface=eth2,type=ethernet alias="Server B",state=1,speed=10
edgeos_interface,interface=eth0,type=ethernet alias="Provider XYZ",state=0,speed=1000

...

edgeos_power voltage=23.41
edgeos_power current=0.37
edgeos_power consumption=8.85
edgeos_temperature,sensor=CPU temperature=66.75
edgeos_temperature,sensor=Board\ 1 temperature=58.25
edgeos_temperature,sensor=Board\ 2 temperature=49.75
edgeos_temperature,sensor=PHY\ 1 temperature=68.50
edgeos_temperature,sensor=PHY\ 2 temperature=57.50

Supported Hardware

:heavy_check_mark: = Works for me!

:x: = No hardware support for this feature :(

Setup

To keep the binary size small, we introduced flavors. This means that only a specific output like influxdb_v2 or prometheus_client is part of the built binary. If you need a different output, create an issue.

Install the prebuild package with your needed flavor:

curl -L -o telegraf.deb https://github.com/x70b1/telegraf-edgeos/releases/download/{RELEASE}/telegraf_{REALEASE}+{FLAVOR}_{ARCH}.deb
dpkg -i telegraf.deb

You can upgrade Telegraf with the same commands.

As you already know from InfluxData's distribution of Telegraf, the configuration is located at /etc/telegraf/telegraf.conf and /etc/telegraf/telegraf.d. The sample config is pre-installed. This needs to be modified for your own use case.

Dashboard

I added a sample Grafana dashboard.

It comes without warranty. You will have to customize it.
