Bottleneck detection
18
The following example enables bottleneck detection on port 5. Alerts are sent when the port is
bottlenecked 50% of the time over any period of 300 seconds (default value), with a minimum of
30 seconds between alerts.
switch:admin> bottleneckmon --enable -alert -thresh 0.5 -qtime 30 5
Displaying list of ports on which bottleneck detection is enabled
1. Connect to the switch to which the target ports belong and log in as admin.
2. Enter the bottleneckmon
--status command to display the ports on which bottleneck
detection is enabled.
If you are using Virtual Fabrics, the output displays ports that do not belong to the logical
switch if the ports were moved out of the logical switch after bottleneck detection was enabled
on them.
Example
switch:admin> bottleneckmon --status
Port Alerts? Threshold Time (s) Quiet Time (s)
=======================================================================
3 N -- -- --
4 Y 0.600 45 300
5 Y 0.500 300 30
6 N -- -- --
Disabling bottleneck detection on a port
1. Connect to the switch to which the target port belongs and log in as admin.
2. Enter the bottleneckmon
--disable command to disable bottleneck detection on a port.
Example of disabling bottleneck detection on port 3
switch:admin> bottleneckmon --diable 3
Changing bottleneck settings on a port
Using the following procedure, you can change whether RASlog alerts are sent and the threshold,
time, and quiet time options. You must first disable bottleneck detection on the port before you can
change the settings.
1. Connect to the switch to which the target port belongs and log in as admin.
2. Enter the bottleneckmon
--disable command to disable bottleneck detection on the port.
3. Enter the bottleneckmon
--enable command to enable bottleneck detection, specify the new
threshold values, and set the alert option.
Example
The following example changes the bottleneck settings on port 4. In this example, the bottleneck
--status commands show the before and after settings.
switch:admin> bottleneckmon --status
Port Alerts? Threshold Time (s) Quiet Time (s)
