[syslog-ng] what is the 'supervising syslog-ng' process?

[Tim Edwards]

We have syslog-ng-client-3.0.5-1.rhel5 installed on several machines.
However on 2 of those Nagios has flagged that there's an extra process
with the command 'supervising syslog-ng'.


Both machine1 and machine2 are Scientific Linux 5.4 (a RHEL clone)
x86_64 Xen virtual machines with the exact same syslog-ng.conf:

[root at machine1 ~]# ps -ef | grep syslog-ng
root     24891     1  0 09:26 ?        00:00:00 supervising syslog-ng

root     24892 24891  0 09:26 ?        00:00:00
/opt/syslog-ng/sbin/syslog-ng --no-caps

[root at machine2 ~]# ps -ef | grep syslog
root      1718  1695  0 09:38 pts/0    00:00:00 grep syslog
root      2137     1  0 Feb01 ?        00:00:09
/opt/syslog-ng/sbin/syslog-ng --no-caps


Can someone explain what this 'supervising' process is?

Thanks
