# T.I.G. Stack for OPNsense Firewall

Telegraf Agent + InfluxDB + Grafana stack to build dashboard from for my OPNsense Firewall & Router

# Telegraf Agent --> InfluxDB

With my influxDB + Grafana connection already set up, I just need to create an OPNsense bucket in my InfluxDB container and connect it to a Telegraf agent to my OPNsense set-up.

First, download the Telegraf plug in to your OPNsense machine. Navigate to System ---> Firmware ---> Plug-Ins and download Telegraf:

Once installed, navigate to Services ---> Telegraf ---> General and enable the agent:

Save settings, then navigate to Telegraf ---> Output. Enable and enter connection information for your InfluxDB2 container:

Save settings, then navigate to your influxDB2 GUI and select your bucket to confirm you're receiving data:

All set, you can now start building your dashboard with Grafana!

# The Dashboard

In Grafana, either load a template or build your own custom dashboard by navigating to Home ---> Dashboards ---> New:

Given that OPNsense was forked from PFsense, you can either find PFsense dashboards and configure variables accordingly, use OPNsense templates, or just build your own dashboard. I used [OPNsense Metrics](https://grafana.com/grafana/dashboards/16197-opnsense-metrics/). Load the dashboard and configure however you'd like!
