When is a metric between a template and a target considered "different"?
The metric is said to be different when any or all the following conditions are true (provided the target does not have "Template Override" set for that metric):
-
The Warning Threshold settings are different
-
The Critical Threshold settings are different.
-
The Collection Schedules are different.
-
The Upload Intervals are different.
-
The number of occurrences (for which the metric has to remain at a value above the threshold before an alert is raised) are different.)
-
For metric extensions, in addition to the above, the OS Command/SQL statement used to evaluate the metric extension is different. Note that this applies only if the name and the return type are the same.
-
The metric extension marked for delete will be shown as "different" on the destination target and the template only if:
-
A metric extension with the same name exists on both the destination target and template.
-
The return type (String, Numeric) of the metric extension is the same on both the destination target and template.
-
The metric type is the same on both the destination target and the template.
