mtail VS snaketail-net

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.

SnakeTail is a tail utility for Windows log files capable of monitoring “large” text logs and event logs (without the need for admin rights). Features support for MDI, tabbed, and floating window modes; saving and loading entire window session; highlighting based on keywords; jump to bookmarks; service stop/start from the tail window; search; display simple process stats in the window title bar; and more. Our thanks for this one go to ITmercinary.

In place of the command window, I use Snaketail. You can make really nice color-coded logs to monitor anything that produces a log (including Nettime).
