Chapter 17 Administrative Tasks for the Sensor
Displaying the Inspection Load of the Sensor
Step 4 Clear the packet nodes.
sensor# clear database nodes
Warning: Executing this command will delete database on all virtual sensors
Continue? [yes]:
Step 5 Enter yes to clear the packet nodes database.
Step 6 Clear the alerts database on a specific virtual sensor.
sensor# clear database vs0 alerts
Warning: Executing this command will delete database on all virtual sensors
Continue? [yes]:
Step 7 Enter yes to clear the alerts database.
Step 8 Clear inspector lists on the sensor.
sensor# clear database inspectors
Warning: Executing this command will delete database on all virtual sensors
Continue? [yes]:
Step 9 Enter yes to clear the inspectors database.
Displaying the Inspection Load of the Sensor
Use the show inspection-load command in privileged EXEC mode to display a timestamp and the
current inspection load of the sensor. Use the history option to display a histogram of the inspection load
over the past 60 minutes and over the past 72 hours.
Use this command to determine the load on the sensor instead of the CPU Usage information from the
show statistics host command. The inspection load is a more accurate representation of the processing
level of the sensor. The calculation of the inspection load has also been enhanced to provide a more
accurate calculation of the sensor load at lower traffic levels.
Note The Processing Load category in the show statistics virtual-sensor output has been renamed to
Inspection Load and shows the same value seen in the show inspection load command.
Note The show inspection-load command is not currently supported for the IPS 4500 series sensors.
To display the inspection load of the sensor, follow these steps:
Step 1 Log in to the CLI.
Step 2 Show the current inspection load with a timestamp of the sensor.
sensor# show inspection-load
sensor 08:18:13 PM Friday Jan 15 2011 UTC
Inspection Load Percentage = 1
Step 3 Show the histogram of the inspection load:
sensor# show inspection-load history
