Installation & Operation Manual 23. Overview
23.9 Faults and Alarms Monitoring
Gateway functionality and service status can be monitored in one of the following
ways:
Polling the status attributes of corresponding MOs
Processing trap notifications issued by the Media Gateway
Trap notifications are issued by the Media Gateway when a fault or an event occurs
that may affect service provided by the Media Gateway or its specific application. Trap
notifications are sent to the SNMP managers (e.g., EMS) and recorded in the trap log
file accessible via the CLI interface.
Trap notifications may be one of the following two types:
Alarms – indicates the problem that currently affects the specific Media Gateway
component; alarms are raised when problem occur and are cleared when the
problem is gone; only alarms that are currently raised are displayed in the EMS
Alarm Browser screen by default.
Events – provides information about a specific event that occurred in the past
and is not necessarily currently relevant to the system; events are not cleared
and therefore should be used for logging purposes only; the EMS Alarm Browser
may be configured to either sort events from alarms or to filter events from the
alarm browser view.
Each trap notification contains the following data:
Name – trap name
Textual Description – detailed description of the problem or informational event
Source – MO where the problem or event occurred
Severity – problem or event severity
Type – generic trap type
Probable Cause – probable problem or event cause
AdditionalInfo1-3 – additional information about the problem or informational
event
In the EMS, trap notifications are displayed in the Alarm Browser located at the bottom
of the screen. The Alarm browser is context-sensitive and displays only alarms that
belong to the selected MO and it’s children. To display all available trap notifications,
click the
button to access the Media Gateway status screen.
