thank you evert for this new style !!

and my question is about mrtg .
can i aske my question about mrtg here ???

i check cpu_load of our router with mrtg ,one for internal router and one for external router ,
both are the same,but just internal router cpu_load works well and the external doesn’t update ,
what would be the problem ?

i remove previuos log and mrtg created new log .
it is ok now,
