esaProbeStatsSeqGaps
Module: CM-SA-MIB
OID (symbolic): CM-SA-MIB::esaProbeStatsSeqGaps
OID (numeric): 1.3.6.1.4.1.2544.1.12.8.1.7.1.17
Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: The total number of sequence gaps across all packets received in the current interval. If (Received Seq Number) is greater than or equal to (Last Received Seq Number + 2)) it is termed as a sequence gap. NOTE: This is not applicable for Y.1731 probes.
What is esaProbeStatsSeqGaps?
esaProbeStatsSeqGaps is a 64-bit performance counter counting sequence-number gaps of two or more across received packets, for the interval that is still being actively collected (the live bin); it does not apply to Y.1731 probes. A sequence gap is an early-warning proxy for packet loss, showing up the moment a packet fails to arrive, so a technician can correlate it against the direct loss counters recorded in the same bin. For example, this live gap count rising in step with the live lost-packet counter confirms the two are seeing the same real loss event rather than an unrelated counting glitch.
