bottleneckMon

--enable
Enables bottleneck detection on the switch. This operation is switch-wide and
affects all F[L]_Ports and F_Ports. This operation enables bottleneck detection on
all eligible ports of a switch, no matter when they become eligible. If you have
Virtual Fabrics enabled and you move ports into a bottleneck enabled logical
switch from another logical switch, bottleneck detection is enabled upon
completion of the move. You can configure optional thresholds and alerts when
you enable the feature, or you can change selected parameters later with the
--config command.
--config
Modifies bottleneck detection parameters on specified ports or, when a port list is
not specified, on the entire switch. Bottleneck detection must first be enabled
before you can fine-tune the configuration with the
--config command. The history
of bottleneck statistics thus far will not be lost for the specified ports and can be
viewed with the
--show option. However, alert calculations restart on the specified
ports when parameters change. This operation is allowed on excluded ports.
The following parameters can be optionally set with the --enable and --config
commands; if omitted, default thresholds apply.
-alert
Enables alerts when configured thresholds are exceeded on the ports that are
enabled for bottleneck detection. The alerting mechanism is by RASlog and
SNMP traps. This operand is optional; if omitted, no alert is assumed. When
-alert
is specified, one or more of the following operands may be specified. If -alert is
not specified and you try to specify additional configuration parameters, the
command fails with an appropriate message.
-cthresh congestion_threshold
Specifies the severity threshold for congestion that triggers an alert. The
threshold indicates the percentage of one-second intervals affected by the
bottleneck condition within the specified time window. The threshold is
expressed as the equivalent fraction between 0 and 1. The default value is
0.8.
-lthresh latency_threshold
Specifies the severity threshold for latency that triggers an alert. The
threshold indicates the percentage of one-second intervals affected by the
bottleneck condition within the specified time window. The threshold is
expressed as the equivalent fraction between 0 and 1. The default value is
0.1.
-time window
Specifies the time window in seconds over which the percentage of seconds
affected by bottleneck conditions is computed and compared with the
threshold. The maximum window size is 10800 seconds (3 hours). The
default is 300 seconds.
-qtime quiet_time
Specifies the minimum number of seconds between consecutive alerts. The
default is 300 seconds. The maximum is 31556926 seconds (approximately
one year).
-noalert
Disables alerts. This is the default state assumed if neither -alert nor -noalert is
specified.
