Monitoring LUN level statistics
A common use of flow monitors is to monitor traffic flowing from a particular ingress port to a
specified LUN.
The following example creates a flow named “lunFlow11” that monitors traffic ingressing on port 5
between device 010502 and device 030700 using LUN 4, and then displays the results of that
flow.
Figure 504 provides an illustration of what occurs in the example.
FIGURE 504 LUN monitoring flow example
LUN Any LUN values defined in the flow definition.
Bi-Directional Whether the flow is bidirectional (yes) or not (no).
Flow Definition Persistence Whether the flow is configured to Persist over switch reboots (yes) or
not (no).
Last Updated Time The date and time the sub-flow was last updated.
