Issue/Introduction
For some interfaces of specific devices, you may often see the event: 0x10d80 that may affect the IN_LOAD and OUT_LOAD monitoring.

One of the possible cause of 0x10d80 is that some X_IN value is > than the corresponding X_OUT value (see KB : Alarms in Spectrum for "IN/OUT LOAD THRESHOLD EXCEEDED” show values over 100%), but also if the data is consistent, per Spectrum design, the SpectroSERVER raises the 0x10d80 event when current LOAD_TOTAL(LOAD_IN + LOAD_OUT) value exceeds default threshold of 200.
Resolution
Increasing the port_perf_valid_result_age may help to reduce the frequency of the 0x10d80 event. This parameter is set in the .vnmrc file located on the SpectroSERVER under:
$SPECROOT/SS
During port performance calculation two attributes read from .vnmrc file. The first attribute is port_perf_valid_result_age (Default 8 sec) and the second one is port_perf_node_ageout (Default 900 secs).
It you configure the port_perf_valid_result_age attribute value to 60 secs this means spectrum polls the interface only once every 60 secs.
If any request comes from oneClick during valid time age, spectrum simply returns already calculated metrics (cached results) instead of new polling on the interface.
The other attribute port_perf_node_ageout value is used for identifying the stale node of an interface in case polling fails.
