Thanks Andreas Nolte, But what i wanted to know was that does mrtg monitor the ifinoctets & ifoutoctets by default or not. Because if we want to monitor the ifinerrors & ifouterrors we have to specifically give the mibs in the .cfg file witht the target[]:. If ifinoctets & ifoutoctets are in default then the cfgmaker specifies only the ifinoctets & not the ifoutoctets, then how does it monitor both of them.
