Traffic/Flows monitoring category
The Traffic/Flows category groups areas that track the source and destination of traffic and flows.
Use traffic and flow thresholds and alarms to determine traffic load and flow and to reallocate
resources appropriately.
lists measures in the Traffic/Flows category and describes each measure.
FCIP circuit packet loss (CIR_PKTLOSS) The number of packets routed through a port exceeds the port
bandwidth.
FCIP tunnel packet loss (PKTLOSS)
1
Monitors the number of retransmitted packets in the tunnel.
Round trip time (RTT)
1
Monitors the round-trip time of the circuit.
Jitter
1
Monitors the variance in round-trip time of the circuit.
Tunnel utilization (TUNNEL_UTIL)
1
Monitors throughput in the channel.
FCIP Tunnel Status (TUNNEL_STATE)
1
Monitors the tunnel state.
1.
Supports only on Brocade 7840.

Description
Receive bandwidth usage percentage (RX)
The percentage of received word frames that exceeds the configured
thresholds.
Transmit bandwidth usage percentage (TX) The percentage of transmitted word frames that exceeds the
configured thresholds.
Trunk utilization (UTIL)
The percentage of utilization for the trunk at the time of the last poll.
Tx Frame Count (TX_FCNT)
The number of transmitted frames for the flow that exceeds the
configured thresholds.
Rx Frame Count (RX_FCNT)
The number of received frames for the flow that exceeds the
configured thresholds.
Tx Throughput (TX_THPUT)
The number of transmitted words for the flow that exceeds the
configured thresholds.
Rx Throughput (RX_THPUT)
The number of received words for the flow that exceeds the
configured thresholds.
IO Read Command Count (IO_RD)
The number of SCSI read commands for the flow that exceeds the
configured thresholds.
IO Write Command Count (IO_WR)
The number of SCSI write commands for the flow that exceeds the
configured thresholds.
IO Read Data Rate (IO_RD_BYTES)
The SCSI read data rate (mbps) for the flow that exceeds the
configured thresholds.
IO Write Data Rate (IO_WR_BYTES)
The SCSI write data rate (mbps) for the flow that exceeds the
configured thresholds.
