Can Telegraf package gather latency/packet loss information?
In pfSense, you can go to the Status, Monitoring page, and generate a pretty graph showing pocket loss, latency etc.
I just setup Telegraf on my XG-7100, and it's displaying some basic information like throughput in InfluxDB. However I don't see any latency/packet loss info?
To answer myself - the "ping" plugin in Telegraf can collect similar data, and output to things like InfluxDB (or other databases).
However, the Telegraf package is currently x86 only on pfSense - ARM builds are broken for pfSense:
Yes, Telegraf can do this. It can use the same data as gathered by dpinger and displayed in the graph in your first post.
First you need a script, that will gather this data from dpinger and output it in a format that Telegraf will be able to digest. I made a python script some time ago. You can find it here: https://gist.github.com/fastjack/a0feb792a9655da7aa3e2a7a1d9f812f. Copy that script to /usr/local/bin and make it executable.
Second you need to tell Telegraf to call that script. For this you'll need to add this to your telegraf.conf:
[[inputs.exec]] commands = ["/usr/local/bin/gateways.py"] timeout = "5s" data_format = "influx"
Finally restart Telegraf so it will pick up the changed config.
Please note that any changes you make in the pfSense web UI in Services > Telegraf will recreate the telegraf.conf from scratch and clobber your modifications.
