The load caused by each individual log can be estimated from the diagrams and models below.
Finally make an addition.
The lowest configured value of sampling interval or log interval for an actual log is used when
entering the diagrams. In that way the different load caused by a momentary log and a mean
value log is practically considered.
A primary and a secondary log is treated in the same way when analyzing the CPU load.
The secondary log normally gets its data from a primary log. This means that the load data from
the primary log and the secondary log must be added up.
