I think it is similar to my problem of trying to graph the number of active VOIP calls. Cisco doesn't provide a single mib entry that you can just poll the number and be done. They often provide a table, and you need to count the number of entries in the table, or perhaps the number of entries in a table with a a particular value. MRTG does not currently have a native method for performing this task. So, you need to write a short perl script that will do the polling and return the values that are desired. This is somewhat inefficient, as it loads a separate instance of perl into ram (and ram is already precious when you have several thousand targets). I notice that in 2.15 there is a WaLK psuedo-OID that enables MRTG to work around really silly things like a box that won't respond to an snmp get, but will work fine with an snmpwalk. I just deployed that particular solution, and it works very well for certain silly boxes. And I think I want to write a similar extension to count walk-entries (or, optionally, count walk-entries with a particular value). But that will probably take me a couple of weeks, particularly since it involves twiddling with the Target Parsing regex. > > Thanks all :) > > -- > Ross. > > _______________________________________________ > mrtg mailing list > [email protected] > https://lists.oetiker.ch/cgi-bin/listinfo/mrtg _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
