In my cacti 088a and Thold plugin (version 0.5) when using Baseline Deviation I can choose only
6 minutes average
24 minutes average
4.8 hours average
for Time reference in the past
.
Is there a way to specify my own reference in the past?
I need to detect gradual but persistent decline in certain readings, say steady signal degradation within a whole month rather than just detecting rapid changes with those default time windows I listed above..
