Coral Fault Manager
The Coral Fault Manager (CFM), from Tadiran’s latest line of advanced Coral management
products, offers an at-a-glance global view of the health of your entire Coral network,
with:
- Network-wide accessibility
- Real-time fault detection
- Rapid assessment of fault severity, so you can focus on the most critical problems
first
- Early detection for efficient preventive maintenance
- Alarm event alerts sent via email or SMS message
- Fast troubleshooting
Whenever there is an alarm event, the Coral responds by sending an alert through
an IP network to the CFM server application. The CFM filters out redundant alarm
information and assigns a severity value to the alarm. If the severity is above
zero, it:
- Updates current alarm status
- Recalculates overall alarm status of the relevant Coral
- Sends an email or SMS, according to the severity of the alarm event
- Records the alarm event in the CFM alarm history database
In addition, each Coral Server transmits its alarm status periodically to the CFM.
If the CFM does not receive this periodic status report it concludes that a critical
failure has occurred.
The overall alarm status change is sent as an SNMP trap to any standard SNMP NMS
application such as Castle Rock or HP Openview. The system manager can view the
alarm status of all Coral Servers in the network by surfing to the NMS application
server using a standard web browser.
The CFM-SP (Coral Fault Management SNMP Proxy) is proprietary Tadiran software running
on a Linux operating system. CFM-SP interfaces with Coral Servers via an IP network,
while an STIP unit is used to convert the Coral’s serial I/O to IP for transmission
over the network.
