Alerting when value changes since previous poll

lawbar90

I have a WIndows PowerShell template that counts a value on my database, and then outputs that value.

I want to know:

How can I change the states of the monitoring to critical, if the value increases since the last poll.

Example:

Poll 1 - Value = 100

Poll 2 - Value = 100

Poll 3 - Value = 101

I want it to go critical on Poll 3.

Cheers

Enable Count statistic as difference for that component. This takes the difference between the current poll against the previous poll  So a non-alerting state would be when the statistic is 0. The critical threshold would be defined as greater than 0. Typically this is used to calculate the rate of change in a stat, but should work just as well for you here.
