I'm trying to figure out some very puzzling issue in our ganglia system.
We are using ganglia 3.1.1.We get strange issue that some metric always have
too large TN.
The system is configured as:
-We have gmond deployed on 16 nodes (A-001--A008, B001--B008).
-Gmond is configured to use multicast
The TN value is simple indicating the time offset from the reported
timestamp that the metric was last received from the managed node. In
other words it is the age of the metric. A large number would indicated
that the metric value has not been updated for a long period of time.
