Are you aware of `prometheus-node-exporter-lua` and `mtail` and what made you decide to go for client_python #5

Hi, I'm currently looking at adding more things running on my OpenWrt to Grafana.

In the process I came across https://openwrt.org/packages/pkgdata/prometheus-node-exporter-lua as the "official" OpenWrt exporter with a whole bunch of scripts to export specific things.

And https://github.com/google/mtail while looking for a dashboard for dnscrypt-proxy2. (I'm currently running blocky in a container as DNS/adblock, but it's not that great except for the nice dashboard)

Do you have any experience with either?

And how much work was it to write this exporter? Trying to decide if its maybe worth to play around with writing one for other stuff ...

I wasn't sure if prometheus-node-exporter-lua can be modified or how to do it as I think it exports a set range of metrics. So I used prometheus python client for this as I have used it a few times for other things. The downside of using python is that it uses up a lot of storage on OpenWRT.

I did not know about mtail. I like using the python prometheus client, I have another exporter here in a docker container that converts http json api into prometheus metrics and another container here that runs a process that outputs json data and converts to prometheus metrics.

I haven't looked into how it works, but there are a lot of specific exporters, so I think they are basically just scripts using the main exporter.

Will post more on how things go after I investigate ...
