I added the above 2 to my mrtg.cfg

Now, I can see graphs. But , Some graphs show traffic, some graphs do not.

for e.g-

Server Requests @ cacheproxy does not show any traffic

HTTP In/Out Traffic @ cacheproxy shows traffic. It is OK.

In addition to that, I added some more to mrtg.cfg from below URL.

http://chrismiles.info/unix/mrtg/mrtg-squid.cfg

the below graphs DO NOT show any traffic.
HTTP Hits @ 192.1.54.62
Server Errors @ 192.1.54.62
HTTP Errors @ 192.1.54.62
HTTP all service time @ 192.1.54.62
Current Swap Size @ 192.1.54.62

the below graphs show traffic.
Server In/Out Traffic @ 192.1.54.62
Storage Mem Size @ 192.1.54.62
Storage Swap Size @ 192.1.54.62
HTTP I/O number of reads @ 192.1.54.62
DNS service time @ 192.1.54.62

Could you pls expalin why? Where have I go wrong?

Anyway, here is the output of squidclient mgr:info
