High Availability Alerts

Use the information in the following tables to learn about all possible HA alerts in detail that are raised by Fault Management.

HA Service (Non-Redundant)

31050 HA Service (Non-Redundant)
Description Send an alert when the standby node is not up which indicates that the system has no redundancy.
Preconditions

Starting with EFA 3.1.0, a timer task periodically monitors the status of the standby node, and raises an event to the fault management system. The fault management system raises an alert to the user to indicate that the system is not fully redundant.

  • For HA events, the polling frequency is every minute.
Requirements
Alert shows the following data:
  • Node IP
The following example shows an alert when the standby node is down: 
<114> 2003-10-11T22:14:15.003Z xco.machine.com FaultManager - -     
   [meta sequenceId=”47”]

}

HA Service (Fully Redundant)

31051 HA Service (Fully Redundant)
Description Send an alert when the standby node is up and ready which indicates that the system is fully redundant.
Preconditions

A timer task periodically monitors the status of the nodes and raises an event to the fault management system. The fault management system raises an alert to the user to indicate that the system is fully redundant.

  • For HA events, the polling frequency is every minute.
Requirements
Alert shows the following data:
  • None
The following example shows an alert when the standby node is up and running:

}

HA Service (Failover Occurred)

31052 HA Service (Failover Occurred)
Description Send an alert when an HA failover has occurred.
Preconditions

A timer task periodically monitors the status of the nodes and raises an event to the fault management system. The fault management raises an alert to the user to indicate that an HA failover has occurred.

  • For HA events, polling frequency is every minute.
Requirements
Alert shows the following data:
  • Active IP
The following example shows an alert when there is a HA failure:
<114>1 2003-10-11T22:14:15.003Z xco.machine.com FaultManager - -
