Description
Interval
Max/Min
Each log point consists of the
maxor min value since the
previous log point. The min‑
and max values are calculated
as a rolling average with per
second resolution.
1s, 2s, 15s, 1min, 5min, 15min,
1h, 24h, 1 month
Mean
Each log point consists of the
mean (average) value since the
previous log point. The mean is
calculated with per second
resolution.
1s, 2s, 15s, 1min, 5min, 15min,
1h, 24h, 1 month
Sum
The log sums the values since
the previous log point. This is
done with per second
resolution. The sim log can be
used for example when
calculating operating time.
1s, 2s, 15s, 1min, 5min, 15min,
1h, 24h, 1 month
Note that all logs except for smart log are implemented as circular buffers. This means that older log
values will be rotated out of memory when the buffer is full. There is a reserved memory for each log
area, which is not affected by the other logs. For example; the contents of the long term log are not
affected by the short term log filling up and rotating out old log values. The exception is the smart log
where older values are not deleted, they are instead converted to longer intervals.
These are the log areas:

Periodic logs with interval < 1h
