No, rsyslog requires a full restart to update the running config. This is needed because the config actually loads code into rsyslog, so it's a very non-trivial effort to update the running config.

We have opted to punt on this and just accept that a config change requires a restart.

We do have table lookups that can be re-loaded while running, and are looking at being able to do some minor tweaks to the config (add/remove inputs of a type already defined in the config)

What is it that you are doing that is causing you to want to change the config frequently enough for the restarts to be a problem?

Subject: [rsyslog] signal based mechanism to read/re-read the configuration
    files

Hi,


Is there a signal based mechanism to read/re-read the configuration files?


As per my understanding, If the configuration files are updated or use the 
backticks option provided in latest update, rsyslogd has to be restarted as the 
rules are loaded once during startup.


The signal based approach will help to utilize the backticks option to not 
restart rsyslogd.


Appreciate your input and Comments.

Lak.
