Exporting CPU and memory usage information to the sFlow collector
With sFlow verion 5, you can optionally configure the sFlow agent on the Dell PowerConnect device
to export information about CPU and memory usage to the sFlow collector.
To export CPU usage and memory usage information, enter the following command.
PowerConnect(config)# sflow export system-info
Syntax: [no] sflow export system-info
By default, CPU usage information and memory usage information are not exported.
Specifying the polling interval for exporting CPU and memory usage information to
the sFlow collector
The polling interval defines how often sFlow data for a port is sent to the sFlow collector. With sFlow
version 5, you can optionally set the polling interval used for exporting CPU and memory usage
information.
For example, to set the polling interval for exporting CPU and memory usage information to 30
seconds, enter the following command.
PowerConnect(config)# sflow export system-info 30
Syntax: [no] sflow export system-info <seconds>
You can specify a polling interval from 5 seconds to 1,800 seconds (30 minutes). The default
polling interval for exporting CPU and memory usage information is 300 seconds (5 minutes).
Exporting CPU-directed data (management traffic) to the sFlow collector
You can select which and how often data destined to the CPU (for example, Telnet sessions) is sent
to the sFlow collector.
CLI commands allow you to do the following:
Enable the sFlow agent to export CPU-directed data
Specify the sampling rate for exported CPU-directed data
Enabling the sFlow agent to export CPU-directed data
To enable the sFlow agent on a Dell PowerConnect device to export data destined to the CPU to the
sFlow collector, enter the following command.
PowerConnect(config)# sflow export cpu-traffic
Syntax: [no] sflow export cpu-traffic
By default, this feature is disabled. The sFlow agent does not send data destined to the CPU to the
sFlow collector.
Specifying the sampling rate for exported CPU-directed data
The sampling rate is the average ratio of the number of packets incoming on an sFlow-enabled
port, to the number of flow samples taken from those packets. You can optionally set the sampling
rate for CPU-directed data exported to the sFlow collector. For example, to set this sampling rate to
2048, enter the following command.
PowerConnect(config)# sflow export cpu-traffic 2048
