• Oracle GoldenGate Monitor Agent is up and running.
• The OGG Home page does not display a Warning icon and a tool tip in either of the conditions:

11.6.2 False Alerts for Oracle GoldenGate Microservices Targets

Ensure the following:

• The out-of-box rule for metric collection error is disabled.
• A ruleset and rule are created in the Oracle Enterprise Manager as follows:
  1. Ensure that the Ruleset applies only to the targets, such as group of GoldenGate targets or specific GoldenGate targets.
  2. Create a new rule for event type Metric Evaluation Error.
  3. Under Actions, select the delay equivalent to 30 minutes, and select Only execute the actions if specified conditions match > Event has been open for specified duration and enter a value for Event has been open for.

  4. Setup compression as shown in the following screen shot. This will compress all collection error events from a target in an hour; events will be compressed only if they are open for more than 30 minutes (based on the delay setting in the screen shot).
