Setting bottleneck detection alerts

Switch-wide sub-second latency bottleneck criterion:
====================================================
Time threshold
Severity threshold
Switch-wide alerting parameters:
============================
Alerts
Latency threshold for alert
Congestion threshold for alert - 0.800
Averaging time for alert
Quiet time for alert
Example of status output showing that only a congestion alert at the switch level has been set
switch:admin> bottleneckmon --status

Setting bottleneck detection alerts

You can configure Fabric OS to log per-port alerts based on the latency and congestion history of
the port. Alerts are generated based on the number of affected seconds over a specified period of
time. If the number of affected seconds is higher than the threshold, an alert is generated.
This evaluation is done independently for latency and congestion.
The bottleneckmon -alert parameters described below determine whether an alert is generated
and what for.
For example,
congestion bottleneck and 3 seconds are affected by a latency bottleneck.
