Configuring the NmsTrapReceiver

NNMi provides the following user-configurable settings:

  • trapReceiverReplay

    The trapReceiverReplay setting is the time delta used to replay traps during startup after a failover, when the standby node switches to become the active node. (The default time is 10 seconds).

    Note The trapReceiverReplay setting applies to application failover and high availability (HA) environments only.

  • trapReceiverJmsTTL

    The trapReceiverJmsTTL option sets the maximum time that the TrapReceiver will cache traps. The default setting is 5 minutes. If jboss is down for longer than this time, data is lost.

    Tip Before you configure this setting, time a failover to determine a benchmark, and then set the trapReceiverJmsTTL to be double that time.

See the nnmtrapconfig.ovpl reference page or the Linux manpage for more information about how to modify such settings.

Note For proper operation, it is critical that clocks are synchronized between the active and standby nodes. Otherwise, you might experience a large duplication or loss of traps.

For more information, see the nnmtrapconfig.ovpl reference page, or the Linux manpage.

Note When making TrapReceiver changes under High Availability, you must make the changes on both nodes in the cluster. You then need to stop and restart the TrapReceiver process (see Starting and Stopping the NmsTrapReceiver Process).
