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?
