[syslog-ng] syslog-ng Stats

[Frank Wilkinson]

Hi,
I'm new to syslog-ng. 
please forgive.

Can someone please... explain these:
processed='center(queued)=2836986327',
dropped='dst.udp(sopher2udp#0,udp,xxx.xxx.xxx.xxx:514)=104396', 
processed='dst.udp(sopher2udp#0,udp,xxx.xxx.xxx.xxx:514)=1395253254',
stored='dst.udp(sopher2udp#0,udp,xxx.xxx.xxx.xxx:514)=0', 

and what needs tweaking?

We have:
