15.11.2 Clock synchronization

All NNMi management servers in your network environment that participate in global network management (global managers and regional managers) or single sign-on (SSO) must have their internal time clocks synchronized in universal time. Use a time synchronization program, such as the Linux Network Time Protocol Daemon (NTPD) tool or one of the available Windows operating system tools.

If you see the following message at the bottom of the NNMi console:

NNMi's self monitoring has detected a problem (Minor). Please see Help > System Information > Health for details.

Check the nnm.log file on the global manager for the following message:

SEVERE
[com.hp.ov.nms.topo.spi.server.bridge.BridgeConnectionSelectorImpl] Not connecting to system server-name due to clock difference of number-of-seconds. Remote time is date-time.

Perhaps the clocks have drifted apart and need to be resynchronized.

NNMi will disconnect the regional manager connection within a few minutes of output of this message to the log.

NNMi Self Monitoring will also detect the following problem:

[Minor] The connection to the regional manager 'name' is down.
