Risks, Limitations and Assumptions

  • The integration supports Critical and Recovery failure notifications for the following scenarios when App Failure Notifications are enabled in the configuration:
    • Connectivity Exception
    • Authentication Exception
  • The integration sends duplicate or repeated failure alert notifications every 6 hours.
  • The integration does not support automatic monitoring pause or resume actions based on the above alerts. However, you can configure metrics to monitor the wlan-controller resource and generate alerts based on threshold values.
  • OpsRamp sets the default SNMP port value to 161 for connecting to the Wireless LAN Controller via SNMP. You can modify this value anytime from the application configuration page.
  • Component-level thresholds can be configured at the individual resource level.
  • Support for latest snapshot metrics is available starting from Gateway version 15.0.0.
  • Wireless LAN Controller Access Point native-type filtering not working as expected.
  • The application will not delete Discovered Access Point resources. This is intentional behavior observed in the SNMP app.
  • Case 1:
    When an access point is down on the WLAN controller, it will not appear in the SNMP GET response for the list of access points. The access point may come back online after some time.
    Case 2:
    When an access point is moved from one WLAN controller to another, it will not appear in the SNMP GET response for the original controller. The access point may later be discovered under the new WLAN controller.
    Since there is no reliable way to distinguish whether an access point is truly deleted or just temporarily down/moved (as described in Case 1 and Case 2), so we are not delete these resources.
