TNS- messages not reported in OEM
I have set the following metric as per below, but no Alerts are reported within GC.
I have tried a number of settings but nothing has the desired effect of producing alerts. Here are the latest settings I have used. I am not sure of the wildcard SYNTAX so have used % in the Warning and * in the Critical.
Metric
TNS- Error Code
Collection Schedule Every 15 Minutes
Warning Threshold = %TNS%
Critical Threshold = *TNS*
