<p>There was an issue that on newer systemd based platforms the systemd-journal () plugin doesn&#39;t load. You should see this on stderrr during startup. It is a pretty recent issue maybe #914?<u></u><u></u></p>
<p>Do you have systemd? Do you have a separate libsystemd-journal.so or just a monolithic

&gt;<br>
&gt; Hi All,<br>
&gt;<br>
&gt; I was successful  in  compilation  and installing syslog-ng<br>
&gt;<br>
&gt; While  spawning   syslog-ng,  I am getting  source plugin system not found.<br>
&gt;<br>
&gt; Following is the error. Please help me on this<br>
&gt;<br>
&gt; TOR #-&gt; /sbin/syslog-ng<br>
&gt; Error parsing source, source plugin system not found in //etc/syslog-ng.conf at line 10, column 2:<br>
&gt;<br>
&gt;         system();<br>
&gt;         ^^^^^^<br>
<br>
What is the exact content of your syslog-ng.conf file?<br>
Did not you forget to include the scl?<br>
<br>
Cheers,<br>
Gyu<br>
