Jeltz	529550f594	Don't use 'imjournal' ('imuxsock' is already used) ... I still don't understand why it increased the size of the firewall logs by a factor of 5 to 10, but we don't really need structured logs from systemd-journald and the author seems to discourage it's use, so I will not investigate further.	2021-03-02 00:46:16 +01:00

Jeltz	c65b3f090b	Compress and delete old remote logs ... Logrotate is not used because I didn't found an easy way to configure it to handle the compression/deletion of log files already rotated by rsyslog (it is probably possible, but I found the script to be easier).	2021-03-01 03:58:58 +01:00

A call to sendLogsToRemote for logs received through RELP/UDP has been added (to send them to Logstash/Redis/…), so common.conf's prefix must be lower than collector.conf's. Note: future "third-party" config files will also call sendLogsToRemote and thus will also have to use a prefix higher than 10.	2021-03-01 02:15:28 +01:00
