[pmg-devel] [PATCH v2 pmg-docs 2/2] add documentation for the pmg-log-tracker

[Mira Limbeck <m.limbeck@proxmox.com>]

The Tracking Center makes assumptions which are working fine for most of
the users, but not for some.
It might be useful for some users to know that this exists and is the
backend for the Tracking Center.

v2:
 - reworded based on Dylan's suggestions
 - removed reference to pmg-log-tracker manpage which doesn't yet exist

+pmg-log-tracker - Backend for the Tracking Center
+=================================================
+:pmg-toplevel:
+endif::manvolnum[]
+
+`pmg-log-tracker` is the backend for the Tracking Center. It parses the syslog
+files in `/var/log/` for mail information. You can specify a different file to
+parse, for example the mail log `/var/log/mail.log`, using the `-i` option.
+
+As an example, parsing the mail.log file for everything between the 1st and 15th
+of July would be possible with the following command:
+----
+pmg-log-tracker -i /var/log/mail.log -s "2021-07-01 00:00:00" -e "2021-07-15 23:59:59"
+----
+
+Start time `-s` and end time `-e` are optional. By default the end time will be
+the current time and the start time will be 0:00 of the current day.
+
+With the `--verbose` option, additional info will be printed, such as the
+complete log for every mail.
+
+It is also possible to filter the log entries based on hostname, from address,
+to address, and other parameters. For a complete overview of all available
+options, see `pmg-log-tracker --help`.
+
+As a side effect of parsing the syslog, which doesn't contain information about
+the year of the entries, the year passed to the `-s` and `-e` options has to
+be the current one, rather than the one in which the logs were actually created.
