Differences In MIB And MRTG Terminology

Differences In MIB And MRTG Terminology

Always keep in mind that MRTG refers to MIB counter values as counter values. It refers to MIB integer and gauge values as gauge. By default, MRTG considers all values to be counters.

MRTG doesn't plot counter values as a constantly increasing graph, it plots only how much the value has changed since the last polling cycle. CPU usage is typically tracked by MIBs as a counter value; fortunately, you can edit your MRTG configuration file to make it graph this information in a percentage use format (more on this later).

The syntax type, the MIB object name, and the description of what it does are the most important things you need to know when configuring MRTG; I'll come back to these later.
