AVG_INGRESS_DEPTH:
Average Depth of the Ingress Queue
through the sample interval
RxR_OCCUPANCY.IRQ / SAMPLE_INTERVAL
AVG_INGRESS_LATENCY:
Average Latency of Requests through the
Ingress Queue in Uncore Clocks
RxR_OCCUPANCY.IRQ / RxR_INSERTS.IRQ
AVG_INGRESS_LATENCY_WHEN_NE:
Average Latency of Requests through the
Ingress Queue in Uncore Clocks when Ingress
Queue has at least one entry
RxR_OCCUPANCY.IRQ /
COUNTER0.OCCUPANCY{edge_det,thresh=0x1}
AVG_TOR_DRDS_MISS_WHEN_NE:
Average Number of Data Read Entries that
Miss the LLC when the TOR is not empty.
(TOR_OCCUPANCY.MISS_OPCODE /
COUNTER0_OCCUPANCY{edge_det,thresh=0x1}))
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182
AVG_TOR_DRDS_WHEN_NE:
Average Number of Data Read Entries when
the TOR is not empty.
(TOR_OCCUPANCY.OPCODE /
COUNTER0_OCCUPANCY{edge_det,thresh=0x1})
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182
AVG_TOR_DRD_HIT_LATENCY:
Average Latency of Data Reads through the
TOR that hit the LLC
((TOR_OCCUPANCY.OPCODE -
TOR_OCCUPANCY.MISS_OPCODE) / (TOR_INSERTS.OPCODE -
TOR_INSERTS.MISS_OPCODE))
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182
AVG_TOR_DRD_LATENCY:
Average Latency of Data Read Entries
making their way through the TOR
(TOR_OCCUPANCY.OPCODE / TOR_INSERTS.OPCODE)
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182
AVG_TOR_DRD_LOC_MISS_LATENCY:
Average Latency of Data Reads through the
TOR that miss the LLC and were satsified by
Locally HOMed Memory. Only valid at
processor level == don't add counts across
Cbos. NOTE: Count imperfect. Will be
polluted by remote hits where memory's
home node is local memory.
(TOR_OCCUPANCY.MISS_OPCODE /
TOR_INSERTS.MISS_OPCODE)
with:Cn_MSR_PMON_BOX_FILTER.{opc,nid}={0x182,my_node
}
AVG_TOR_DRD_MISS_LATENCY:
Average Latency of Data Reads through the
TOR that miss the LLC
(TOR_OCCUPANCY.MISS_OPCODE /
TOR_INSERTS.MISS_OPCODE)
with:Cn_MSR_PMON_BOX_FILTER.opc=0x182
