Object Description
Receiver Statistics
Owner This field shows the current owner of the sFlow configuration. It assumes one of three values as follows:
  • If sFlow is currently unconfigured/unclaimed, Owner contains <none>.
  • If sFlow is currently configured through Web or CLI, Owner contains <Configured through local management>.
  • If sFlow is currently configured through SNMP (Simple Network Management Protocol), Owner contains a string identifying the sFlow receiver.
IP Address/Hostname The IP address or hostname of the sFlow receiver.
Timeout The number of seconds remaining before sampling stops and the current sFlow owner is released.
Tx Successes The number of UDP datagrams successfully sent to the sFlow receiver.
Tx Errors The number of UDP datagrams that has failed transmission.
The most common source of errors is invalid sFlow receiver IP/hostname configuration. To diagnose, paste the receiver's IP address/hostname into the Ping web page (Diagnostics > Ping/Ping6).
Flow Samples The total number of flow samples sent to the sFlow receiver.
Counter Samples The total number of counter samples sent to the sFlow receiver.
Port Statistics
Port The port number for which the following statistics applies.
Rx and Tx Flow Samples The number of flow samples sent to the sFlow receiver originating from this port. Here, flow samples are divided into Rx and Tx flow samples, where Rx flow samples contains the number of packets that were sampled upon reception (ingress) on the port and Tx flow samples contains the number of packets that were sampled upon transmission (egress) on the port.
Counter Samples The total number of counter samples sent to the sFlow receiver originating from this port.
