Troubleshoot baseline thresholds

Thresholds could not be calculated, standard deviation is zero
There has been no statistically significant deviation of the collected metric during the baseline period. Without some variance in the polled value, it is not possible to determine a valid warning or critical threshold. For example if you poll Disk I/O statistics on an inactive volume, the value is always zero and there is no way to statistically know whether 1 is bad, or if 1.000.000 is still good.
The recommended warning or critical thresholds are less then minimum value for the statistic
This occurs when the Less Than, Greater Than operators are changed, but the values are not updated. For example, when you have a Greater Than operator, the warning threshold cannot be greater than the critical threshold. The inverse is true for the Less Than operator.
