For clues to resolve any issues you encounter, review alerts and alarms. For instance, EdgeConnect appliances issue alarms on half duplex that can help you find and correct service issues quickly. Many alarms include recommended actions for issue resolution.
For an overview of alarms, search for the Alarms Tab topic in the Orchestrator User Guide.
The Orchestrator has four main levels for alarms:
- Critical (red). Critical alarms are service-affecting and require immediate attention. They reflect conditions that adversely affect an appliance or indicate the loss of a broad category of service.
- Major (orange). While service-affecting, major alarms are less severe than critical alarms. They reflect conditions that should be addressed in the next 24 hours. An example would be an alarm caused by an unexpected traffic class error.
- Minor (yellow). Minor alarms are not service-affecting and can be addressed at any time. Examples include alarms caused by a user who has not changed their account’s default password, a degraded disk, or a software version mismatch.
- Warning (blue). Warning alarms are not service-affecting. They warn of conditions that could become problems over time—for example, an alarm caused by IP SLA being down.
In the Orchestrator, the appliance tree view in the left pane displays the color of the highest severity alarm and the number of alarms at that level. For example, a red “2” next to an appliance name indicates two critical alarms for that appliance. Hover over the appliance name for brief alarm descriptions, or for more details, click Monitoring, and then click Alarms.
The top-right corner of the Orchestrator displays the number of sites at each alarm level. To view the Alarms page, click this area, and then click View All Alarms.
Some alarms clear themselves automatically after the issue resolves. Some alarms require user intervention.
The Orchestrator Health Map provides a high-level view of a network’s health in hourly increments. It is the ideal place to begin any troubleshooting.
Health Map is available as a widget on the Orchestrator Dashboard. It can also be accessed by clicking Monitoring, and then clicking Health Map.
The Health Map is color-coded, showing health status for hourly blocks based on the filters selected. Click one of the hourly blocks to show the status for the appliance at that hour, as well as any corresponding alerts.
An administrator can adjust the display to reduce noise and focus on attributes critical to the organization. For example, the following settings display alerts across underlay tunnels only.
Use threshold settings to adjust the criticality of an issue and associated color coding.
In the following screenshot, the alarm bar in the top-right corner of Orchestrator indicates that the network is healthy:
When something goes wrong, an alarm appears, indicating the severity level assigned by Orchestrator. Click the alarm type indicator (MAJOR in the example below) to view more details about the alarm.
