Description

Ambari tries to set milliseconds to the "sysUpTime" field:
https://github.com/apache/ambari/blob/8e35277c24cc0ffd897c1dc727b2cc528cb8148b/ambari-server/src/main/java/org/apache/ambari/server/notifications/dispatchers/AmbariSNMPDispatcher.java#L120

but this field accepts hundreds of milliseconds:

The time (in hundredths of a second) since the network
            management portion of the system was last re-initialized.

(https://tools.ietf.org/html/rfc1907#section-2.1)

So after about 50-days in up-time an ambari server is not able to populate "sysUpTime" with a correct value (the max value the field is able to accept is "4294967295" - it is about 50 days in milliseconds).
Exception in ambari-server.log:
