Probe for Nortel CNM 9
Peer-to-Peer failover functionality
The Probe for Nortel CNM supports failover configurations where two probes run
simultaneously. One probe acts as the master probe, sending events to the ObjectServer; the
other acts as the slave probe on standby. In the event of the master probe failing, the slave
probe activates.
While the slave probe receives heartbeats from the master probe, it will not forward events
to the ObjectServer. If the master shuts down, the slave probe will stop receiving heartbeats
from the master and any events it receives thereafter will be forwarded to the ObjectServer
on behalf of the master probe. When the master is running again, the slave will continue to
receive events from the trap forwarder, but will no longer send them to the ObjectServer.
Example property file settings for peer-to-peer failover
The following configuration shows the peer-to-peer settings from the properties file of an
example master probe:
Server :"NCOMS"
RulesFile :"master_rules_file"
MessageLog :"master_log_file"
PeerHost :"slave_hostname"
PeerPort : 5555 # [communication port between master and slave probes]
Mode :"master"
The following configuration shows the peer-to-peer settings from the properties file of the
corresponding slave probe:
Server :"NCOMS"
RulesFile :"slave_rules_file"
MessageLog :"slave_log_file"
PeerHost :"master_hostname"
PeerPort : 5555 # [communication port between master and slave probes]
Mode :"slave"
