pmPortSampleCntrlTag
Module: IB-PM-MIB
OID (symbolic): IB-PM-MIB::pmPortSampleCntrlTag
OID (numeric): 1.3.6.1.3.117.1.2.1.27
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: Used by a performance application when it does a PerformanceSet(PortSamplesControl) to uniquely identify its sample run in case of a collision with another performance application. When an application wishes to start a sample run, it should pick a random Tag value and do a PerformanceSet(PortSamplesControl). If the returned value of Tag does not match the selected value, another application is using the sampling mechanism. In this case the first application must wait for a suitable time and retry its sample.
What is pmPortSampleCntrlTag?
A 4-byte value an application writes when starting a sample run to detect collisions with another application also trying to use the sampling mechanism; if the value read back doesn't match what was written, someone else already grabbed the sampler. Applications should pick a fresh random tag per attempt and retry after a delay if they lose the race.
