Alarms and Events
Alarm and Event Types
The Main/Standby Solution generates alarms and events under certain conditions that are visible in the alarm and event list of any FOXMAN-UN client connected to the Main or the Standby Server. The following table lists all possible alarms and events, their raise conditions and on which server the corresponding alarm or event is visible:
Use Case | Alarm/Event Condition | Alarm/Event | Text | Visible on Server | Remark |
|---|---|---|---|---|---|
Standby Server periodically pings the Main Server. | Main Server not pingable. | Alarm: yes Event: yes | Switchover from Main Server (hostname) to Standby Server (hostname) due to a connectivity loss. Standby Server is now active. | Standby | Will only be created on a Standby Server of type “Warm Standby” after its core services have automatically started up. |
Main Server periodically pings the Standby Server. | Standby Server not pingable. | Alarm: yes Event: yes | Standby Server (hostname) is not reachable. | Main | Will only be created in case the core services of the Main Server are running. |
