[mrtg] Re: Interface counter

[Jerry Heidtke]

Check the mrtg documentation for the fake mib objects ifAdminHack &
ifOperHack. These return 1 for up, 0 for down. So, for the active ports
on an 8 port switch, you could do something like this:

Target[count]:
   ifAdminHack.1&ifOperHack.1:public at 10.20.20.254 +
   ifAdminHack.2&ifOperHack.2:public at 10.20.20.254 +
   ifAdminHack.3&ifOperHack.3:public at 10.20.20.254 +
   ifAdminHack.4&ifOperHack.4:public at 10.20.20.254 +
   ifAdminHack.5&ifOperHack.5:public at 10.20.20.254 +
   ifAdminHack.6&ifOperHack.6:public at 10.20.20.254 +
   ifAdminHack.7&ifOperHack.7:public at 10.20.20.254 +
   ifAdminHack.8&ifOperHack.8:public at 10.20.20.254

Mind the spacing. There needs to be white space around the math
operators, and continuation lines need to be indented.

This will give you one line on the graph of the enabled ports, and the
other line of the active ports. This might get a little unwieldy for a
48 port switch, for example. See if the vendor's private mib has an
object you could use instead. Or, you could write a simple perl script
that walks .1.3.6.1.2.1.2.2.1.8 and counts how many responses equal to 1
it gets.

Try doing this:

Target[count]: 1.3.6.1.2.1.2.2.1.8.101 &
1.3.6.1.2.1.2.2.1.8.101:public at 10.20.20.254

MRTG needs two OID values to graph. :)
