Alarm Severities and States Overview

 

By default, the Junos Space Network Management Platform is monitored using a built-in SNMP manager. The Junos Space Network Management Platform node is listed in the node list (Network Monitoring > Node List), and is referred to as the Junos Space Network Management Platform node.

Alarm Severity

Alarms are ranked by their impact to the network. The following list shows the ranking of alarms in Edge Services Director from alarms that have the most impact to alarms that have the least impact on the network. It also shows the color scheme associated with each level of severity that is reflected in related graphs.

Critical (Red)A critical condition exists; immediate action is necessary.
Major (Orange)A major error has occurred; escalate or notify as necessary.
Minor (Yellow)A minor error has occurred; notify or monitor the condition.
Indeterminate (Blue)An informational message; no action is necessary. Informational alarms do not necessarily indicate an error. It could indicate that a device or entity has changed state.

Administrators can override the default severity of an alarm and set the severity to match their inhouse guidelines.

Alarm State

Once an alarm is active, it has one of these states:

  • Active—Alarms that are current and not yet acknowledged or cleared.

  • Cleared—Alarms that are resolved and the device or entity has returned to normal operation.

Some alarm states go directly from active to cleared state and require little to no administrative effort. However, other alarms with a high severity should be acknowledged and investigated.

In addition to acknowledging and clearing an alarm, you can assign an alarm to someone and you can append a note or annotation to an alarm. Annotations are helpful for documenting the resolution of an alarm or time estimates for a fix. Changes to an alarm’s state are made through the Alarm State monitor in Fault mode.
