So I’m running into an issue. I have a device (OPNsense) that obviously doesn’t have the plugin for Promtail, BUT, I found you could forward the logs from within the telegraf.conf plugin (which Telegraf OPNsense does have) and do an [[outputs.loki]] and forward it to the specific server that loki is on. Works great, but what I don’t understand is how can I use the Labels from within the config-promtail.yml or something similar so I can create a label for “nodename” or “device”.
My understanding with Labels is only if you have Promtail on said device and then do all the options from config-promtail.yml, but since my said server (OPNsense) doesn’t have Promtail, but I can forward the system logs from telegraf, I don’t know how to set up the labels (if I even can…) correctly. Because whatever I put from the examples from the Labels, nothing works (whereas if I had Promtail on device, it would work). Plus I don’t even need to create a Label to begin with, if forwarding logs to Loki using telegraf. The logs still show up on Grafana > Explore.
Anything I can do to sort these better?
