4.21 NetworkBusy

Use this Knowledge Script to monitor the traffic on network interface cards (NICs). This script raises an event if the network interface’s bandwidth utilization exceeds the threshold you specify. This script skips interface card number 1 as a loopback.

NOTE:This script uses the Network Interface Performance Monitor counter to perform its monitoring task. If this performance counter is not available, install the SNMP services to make the counter available.

4.21.1 Resource Objects

Non-WAN wrapper network interface cards

Network interface folder

4.21.2 Default Schedule

The default schedule for this script is Every 30 minutes.

4.21.3 Setting Parameter Values

Set the following parameters as needed:

Description	How to Set It
Raise event?	Set to y to raise an event if the network interface’s bandwidth utilization exceeds the threshold. The default is y.
Collect data?	Set to y to collect data for charts and reports. If enabled, data collection returns the percentage of network bandwidth in use. The default is n.
Ignore network interfaces with no bandwidth counter data?	Set to y to ignore network interfaces that have a bandwidth counter value of zero, which prevents the module from raising events on unplugged interfaces. The default is n.
Maximum percentage network utilization threshold	Specify the maximum percentage of network bandwidth that can be in use before an event is raised. The default is 35%.
Event severity level	Set the event severity level, from 1 to 40, to indicate the importance of an event in which bandwidth utilization exceeds the threshold. The default is 5 (red event indicator).
Network interfaces to exclude	List the display names of all active interfaces that you do not want to be monitored. Separate each interface name with a comma, without any spaces. You can use the asterisk () as a wildcard at the end of a string, along with regular expressions for interface names. The default is: Loopback,Pseudo,isatap,tunnel*. These settings exclude the set of interfaces that are part of the operating system and do not map to actual network cards.
