mtail VS Matomo

You can do that with something like mtail. Basically write expressions that match your logs and produce metrics.

mtail is a standard tool for this.

I use goflow2 to do something like this. I don't specifically use syslog itself for this, but mtail to generate the metrics.

I can recommend mtail. Here is a good example nginx script.

If not, https://github.com/google/mtail might be a good option.

Count the lines with mtail. You can regexp match the values out into labels.

If you want to extract whitebox metrics from logs, maybe all you need is mtail.

You can use mtail (https://github.com/google/mtail) for this. You'll need to figure out how to plug it into your setup, but mtail will do the metrics from logs thing.

Convert your logs to metrics with mtail.

For nginx, you'll need to setup a log parser like mtail because it doesn't really have much for metrics to begin with.

Matomo just released their major v5 upgrade with following key improvements:

There are many good, lightweight, and open-source alternatives to Google Analytics, such as Plausible, Matomo, Fathom, Simple Analytics, and so on. Many of these options are open-source, and can be self-hosted.

You can for example use analytics that aren't spyware, and hence don't even have to try to trick users giving "consent" to things they don't really want.

Seriously: what share of people actually want their behavior to be tracked for ad companies to make more money?

Matomo is a GDPR-compliant and open-source analytics platform. You can either host it yourself or use Matomo’s hosted version. https://matomo.org/

I tried the self-hosted version of Matomo [1][2] a few years back but I remember it was a bit underwhelming for the effort required to set it up.

It seems like you just want a self hsoted google analytics. Theres Plausible , Matomo and Umami for that.
