When a monitor attribute exceeds its defined threshold but fails to generate an alarm, the cause is usually related to data collection gaps, retry logic, or suppression rules. Follow these steps to diagnose the issue.
An alarm cannot be triggered if the system is not successfully collecting data for the attribute.
Action: Navigate to the Monitor Details page and check the Polled Data for the specific attribute.
Verification: Ensure there are no gaps in the data timeline during the period the violation occurred. If data is missing, troubleshoot the monitor's connectivity or credentials first.
In distributed architectures, the threshold must be correctly synchronized and associated at the Probe server level.
Action: Log into the Probe server UI.
Verification: Confirm that the Threshold Profile is actively associated with the monitor attribute specifically on the Probe where the monitor resides.
If the customer has configured retries, alarms will only be triggered after the specified number of consecutive threshold violations.
Go to Settings → Action / Alarm Settings
Scroll to the bottom of the page
Check the value configured for Consecutive Polls Count
Go to View Thresholds
Select the configured threshold
Enable Show Advanced Options
Check the Polls to Try value for each severity (Critical, Warning, Clear)
If the monitor's overall Health is configured to depend on specific attributes, a misconfiguration here can suppress alarms.
Action: In the Probe server, check the Dependent Attribute List for the monitor's Health attribute.
Verification: Ensure the dependency rule is set to "Depends on any 1 selected attributes" and that your specific attribute is included in that selection.
Verification: Check if a "Business Hour" is selected. If so, verify if the expected alert time fell within an "Off-Hour" period.
Poll Data Report: A screenshot or export of the attribute's polled data during the time the alert was expected.
Probe Association Proof: A screenshot from the Probe Server showing the threshold association to the attribute.
Threshold Config: A screenshot of the entire Threshold Edit page (ensure "Advanced Options" are visible).
Debug Logs: * Enable 'Print all Logs' in settings.
Perform a manual "Poll Now" for the monitor.
Once the poll completes, generate and download the latest log zip.
