Hi All, Does syslog-ng have a running script that check the syslog-ng running status? If it crashed or stopped running,this script can make sure to start a new syslog-ng process. This morning,the syslog-ng on my server crashed,and somehow resulted in the server halt. Thanks.

"syslog-ng-ctl stats" is the closest thing. Apart from that, you can save the PID of syslog-ng to a pidfile, and verify that the PID is still present, and if it belongs to syslog-ng (syslog-ng will by default, save a pidfile, FYI).

It was also brought to my attention, that syslog-ng has a built-in supervisor, that will restart it in case it crashes. This can be enabled by starting syslog-ng with the --process-mode=safe-background command-line argument. (What do you know? I never knew this was there! One learns something new every day!) -- |8]

Gergely,

I thought the supervisor was on by default. Am I mistaken to believe this?

You are correct. -- |8], who's been running 3.3 in screen with -Fve for the past couple of months.
