| Data types: |
|
| – Gauge |
A data source of type gauge shows the state of the data source at the
exact moment that Munin is run (every 5 minutes). Any peaks in-between data gatherings, will not be in
the graph. |
| – Counter |
A data source of type counter shows the state of the data source as an
average between two plots (i.e. 5 minutes). Short peaks will therefore be hard to spot, but long peaks
will be spottable, even though it occurs between plots. |
| – Derive |
For the purposes of viewing data, the derive type works the same way as a
counter |
| – Absolute |
Absolute works much as a counter, with the exception that it is assumed
that the counter value is set to 0 upon each read of it. It's not a good idea to run these plugins by
hand in-between Munin runs, since Munin won't receive all the data it expects. |
