What to Do Next
See the “Monitoring NSEL” section on page 1-9.
Monitoring NSEL
You can use syslog messages to help troubleshoot errors or monitor system usage and performance.You
can view real-time syslog messages that have been saved in the log buffer in a separate window, which
include an explanation of the message, details about the message, and recommended actions to take, if
necessary, to resolve an error. For more information, see the “Using NSEL and Syslog Messages” section
on page 1-2.
NSEL Monitoring Commands
To monitor NSEL, enter one of the following commands:
Examples
The following example shows how to display flow-export counters:
hostname (config)# show flow-export counters
destination: inside 209.165.200.225 2055
Statistics:
packets sent 250
Errors:
block allocation errors 0
invalid interface 0
template send failure 0
no route to collector 0
source port allocation 0
The following example shows how to display the flow-export delay configuration:
hostname (config)# show running-config flow-export delay
flow-export delay flow-create 30
The following example shows how to display the flow-export destination configurations:
hostname (config)# show running-config flow-export destination
flow-export destination inside 192.68.10.70 9996
Command Purpose
show flow-export counters
Shows runtime counters, including statistical data and error
data, for NSEL.
show running-config flow-export
Shows the currently configured NetFlow commands.
