2 bottleneckMon --exclude [slot/]port_list Excludes the specified ports from bottleneck detection. No data will be collected from these ports, and no alerts will be triggered for these ports. All statistics history for a port is erased when a port is excluded. Alerting parameters are preserved. It is not recommended to exclude ports from monitoring except under special circumstances, for example, when a long-distance port is known to be a bottleneck because of credit insufficiency. The wildcard (*) port specifier is allowed but not recommended. Use --disable to exclude all ports on the switch. --include [slot/]port_list Includes previously excluded ports for bottleneck detection. Previously configured switch-wide alerts and threshold parameters reapply when bottleneck detection resumes. The wildcard (*) port specifier may be used as a shorthand for removing all exclusions. --configclear [slot/]port_list Removes any port-specific alert parameters from the specified ports and restores switch-wide parameters on these ports. You can still view the history of bottlenecks statistics on these ports. However, alert calculations restart on the specified ports after the parameter reset. This operation is allowed on excluded ports. --disable Disables bottleneck detection on the entire switch. This operation erases all configuration details, including the list of excluded ports, all custom thresholds and alerting parameters for specific ports, and all historical data. --show [[slot/]port |*] Displays a history of the bottleneck severity for the specified ports. The output shows the percentage of one-second intervals affected by the bottleneck condition within the specified time interval. When a single port is specified, the command displays the bottleneck statistic for that port. When the wildcard (*) is specified, the same statistic is displayed for every port on the switch. Additionally, a combined "union" statistic for the switch as a whole is displayed. When used without a port specifier, the command displays the number of ports affected by bottleneck conditions. A "bottlenecked" port in this output is defined as any port that was affected by a bottleneck for one second or more in the corresponding interval. This command succeeds only on online ports. The following operands are optional: -interval seconds Specifies the time window in seconds over which the percentage of seconds affected by bottleneck conditions is displayed in the output. When a port is specified with the --show command, the maximum interval is 10800 seconds (3 hours). When a wildcard (*) is specified, the maximum interval is defined such that the value of -span divided by the value of the interval cannot exceed 30. The interval value must be greater than 0.The default value is 10 seconds. -span seconds Specifies the total duration in seconds covered in the output. When a port is specified with the --show command, the maximum span is 10800 seconds (3 hours). When a wildcard (*) is specified, the maximum span is defined such that the value of -span divided by the value of the interval cannot exceed 30. The span value must be greater than 0. The default value is 10 seconds. History data are maintained for a maximum of three hours per port, so the span can be 10800 seconds at most. When the show command is issued for all ports (*), the maximum duration is defined such that the value of -span divided by the value of the interval cannot exceed 30. 84 Fabric OS Command Reference 53-1002746-01
