<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Odd one I’ve come across, cant find any clues on the web so figured I’d post here.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Trying to get syslog-ng integrated into the Observium NMS package. Not sure whether the problem lies with syslog-ng, PHP or the sucking of data into Observium. Let me explain:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With syslog-ng started in foreground mode ‘syslog-ng -Fevd’ everything works as expected. I see syslog packets coming in via tcpdump, I see the log flash up on the terminal and it correctly routes into the right part of the Observium front
end. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With syslog-ng started as a daemon (from boot - the desired config setup - or with ‘service syslog-ng start’), nothing gets to Observium. I can still see the syslog packets in tcpdump obviously but I’m blind as to what happens to the messages
after that.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One thing I have noticed is that when running syslog-ng in foreground mode, I see “Starting destination program; cmdline='/opt/observium/syslog.php'” in the startup messages and a corresponding process in the ‘ps –lax’ output “php /opt/observium/syslog.php”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With syslog-ng started as a daemon, I do not see this php process in the ps output..<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Bit stuck as to where to look next. Has anyone seen this behavior before?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Centos6.5 and standard packages and configs. System works great otherwise. Syslog-ng config file in its entirety below:<o:p></o:p></p>
