Configuring an sFlow Collector

Use this procedure to configure the device used as either an sFlow Collector or an Application Telemetry Analytics Engine. This device is where the agent sends sFlow datagrams and Application Telemetry packets for analysis.

sFlow supports up to two collectors for each interface slot in the chassis. However, Application Telemetry supports Collector 1 only.

Note

You can configure two Collectors, but Application Telemetry uses Collector 1 only. You must configure Collector 1 before you enable Application Telemetry.
Before you change or remove Collector 1, you must disable Application Telemetry.
By default, Application Telemetry is globally disabled.

About this task

Tip

You can configure the Collector tab to select only the columns you are interested in seeing. By default, the AddressType option does not appear. To make the AddressType column visible, click the down arrow on one of the menu headings, navigate to Columns, and select the AddressType check box.

Procedure

In the navigation pane, expand the Configuration > Serviceability folders.
Click Sflow.
Click the Collector tab.
Configure the fields for Collector 1.
Click Apply.

What to do next

After you configure the sFlow collector, configure the packet sampling rate to enable sFlow on a port or ports.

Collector Field Descriptions

Use the data in the following table to use the Collector tab.


Name	Description
Index	Shows collector 1 and collector 2. The switch exports sFlow and Application Telemetry traffic to the collector.
Owner	Specifies the sFlow collector name. The string length is 1 to 20 characters.
Timeout	Specifies the time remaining (in seconds) before the collector is released and stops sampling. The default timeout is 0, which means the timeout is not used and the switch sends data forever.
Address	Specifies the collector IP address. If the default address is set to 0.0.0.0, no traffic is sent.
Port	Specifies the destination port. The default port is 6343.
IsReachable	Shows whether the sFlow collector is reachable.
NextHop	If the collector is reachable, shows the name or address of the next hop through which the collector is reachable.
