A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An engineer names jvm.* in a detector so one threshold covers a whole family of metrics at once. Why is that wildcard discouraged?
Correct.
Checked against help.splunk.com, August 2026Concept
A threshold only means something against one kind of measurement. A wildcard that sweeps in uptime alongside heap makes the comparison meaningless.
Why C
Splunk documents not using wildcards, warning that a name such as jvm.* can evaluate metrics of different types against the same threshold, which might lead to unexpected results.
