We are having issues with connected APMIA agents showing metric values (CPU, Memory, Disk Utilization) with a value of 0.
Fixed in APMIA 23.10 and later
One issue was due to the snmp timer thread got killed by an unexpected NullPointerException, afterwards only the value 0 is reported for the SystemEdge metrics.
A fix was made in 23.3 to correct the Exception according to the stack trace shown in the log.
Later some further fixes was made in 23.10 as we found the same Exception could be thrown from some other places as well.
