CSCsc85141: RTMT generates directory connection and replication alarms
Symptom:
RTMT generates directory replication and connection alerts in a Call Manager cluster when directory replication appears to be functioning normally.
The following RTMT alerts are seen while the directory service is up and running.
[RTMT-ALERT] DirectoryReplicationFailed
Directory replication failed .
Monitored precanned object has value of 0.
[RTMT-ALERT] DirectoryConnectionFailed
Directory connection failed .
Monitored precanned object has value of 0.
No corresponding DC Directory error messages are seen in the Windows Application Event log.
Conditions:
A Call Manager 4.1(3) cluster running RTMT with more than one subscriber will attempt to test replication status by creating the following object.
"ou=zTestReplStatus--(, ou=CCN, o=cisco.com"
All servers will attempt to create and delete the same object, creating a race condition. RTMT generates alerts regarding the failed replication tests caused by this condition.
Workaround:
If directory replication is not actually broken then this is only a cosmetic issue.
One possible workaround is to disable RTMT alerts for directory replication and connection errors. This workaround has the limitation of not being notified when actual directory replication errors exist.
