README.adoc

postfix_exporter
================

Collects continuesly events from postfix and dovecot via journald.
Exports the collected event-counters and the currently count of queued messages.

queue_exporter
==============

If you only want to check the count of mails in queue, use the `queue_exporter` in the subdirectory.
It has lesser dependencies and a smaller footprint:

* No journald, no ffi, no puma
* ffi and puma need a compiler, which you do not need to install
* Instead of puma, use simple rackup, which provides a simpler webserver.

Usage
-----

For nix, `nix-shell` knows any dependencies.

Any other: You need `libffi` and some gems:

apt install libffi
bundle install

Run puma for testing and use curl for first fetch.

puma

curl http://localhost:9296/metrics

You should see the collected data. On first run, this code be very empty. Wait some minutes to have some emails.

journald should not drop loglines! TODO: /etc/systemd/journald.conf
