Hi,


I'm wondering about how and if at all RSyslog handles voluntary stop
signals: TSTP. I have not been able to find any concrete information on
this, but maybe my google-fu is weak.


If there is no voluntary stop handling, how about mandatory stop signals:
STOP? How will the program behave? My expectation is that it will not
handle any incoming messages, and in the case of UDP they will be lost.



I'm running RSylog 7.4.4 on x86_64 embedded Linux.


The reason I'm wondering this is because I have the need to move the
location rsyslog writes to during the boot phase. RSylog is started early
in the boot phase, when this particular system has no persistent storage
area mounted - the logs go into ramdisk. Later in the boot phase network
storage is attached. At this point, I would like to be able the halt
RSyslog from writing to file, so that the logs on ramdisk can be moved, and
then continue to be appended at the new location. Just sending a HUP signal
to rsyslog could cause out of order or lost logs, depending on the order of
doing move compared HUPing.


Any ideas on this would be much appreciated.


Best Regards

Anders
