Alarm severity levels

Seriousness of the alarm. The level of severity can be either major (red) or minor (yellow).

  • Minor (yellow or amber)—Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance. For example, if the device temperature has reached the yellow alarm threshold, a yellow system alarm is generated.

  • Major (red)—Indicates a critical situation on the device that has resulted from one of the following conditions. A red alarm condition requires immediate action.

    • The ctpd process is non-operational.

    • One or more hardware components have exceeded temperature thresholds.

Alarm types

Alarms include the following types:

  • Chassis alarm—Predefined alarm triggered by a physical condition on the device such as a power supply failure or excessive component temperature.

  • System alarm—Predefined alarm that might be triggered when the ctpd process fails to start up.
