3. Select a time interval for monitoring the flow in the Time duration list.
Possible values are 30 minutes, 1 hour, 6 hours, 12 hours, 1 day, 3 days, 1 week, and 1
month.
4. Click the right arrow button to display the selected flow in the Flows table.
You can sort the Flows table by clicking any column head. You can reverse the sort order by
clicking the column head again.
5. Select the SCSI check box to display SCSI-related measures.
SCSI-related measures include SCSI read count, write count, read rate, write rate, read data,
write data, and read and write frame data.
Clear the check box to hide SCSI-related measures.
6. Select the Frame check box to display frame-related measures.
Frame-related measures include transmit (Tx) and receive (Rx) frame count, transmit frame
and receive frame rate, transmit and receive word count, and transmit and receive throughput.
Clear the check box to hide frame-related measures.
7. Review the sub-flow data for the selected Flow Mirror flow.
NOTE
Flow Mirror statistic counts greater than zero imply that the mirrored flow is functioning, but
should not be inferred as accurate counts at this time.
The Flows table, as shown is Figure 514 , displays statistics and data for the selected flows. The
Flows table has the following general characteristics and functions:
•
Data updates dynamically every 5 minutes. Sort the table by clicking any column head. You
can reverse the sort order by clicking the column head again.
•
Locate an ingress port, egress port, source device, and destination device in the Product
List or Topology Map by right-clicking a sub-flow in the Flows table and selecting Locate >
port_type (where port_type is Ingress port, Egress port, Source device, or Destination
device).
•
Highlight inactive sub-flows in gray by selecting the Show inactive flows check box.
Inactive sub-flows indicate no updates to sub-flow statistics for over 15 minutes.
Clear the check box to hide inactive sub-flows.
•
Display a flow in a performance graph. Select a row in the Flows table and select
Performance Graph >
graph_or_report (where graph_or_report is Real Time Graph,
Historical Graph, or Historical Report).
Refer to “Performance integration with Flow Vision” on page 1220" for additional details.
Note that the Performance Graph list is only available when there is at least one sub-flow
selected in the Flows table.
•
A single flow definition may yield data in multiple rows in the Flows table. For example, if
you defined the flow definition source ID (SID) and destination ID (DID) as *, this might
result in five rows if the source is communicating with five destination IDs. In the case of a
learning flow, a root flow also displays to summarize all sub-flows.
