Use this Knowledge Script to monitor network data received/transmitted for a virtual machine. This script raises an event if the rate of network received/transmitted exceeds the threshold you set. This script monitors and collects data for the following performance metrics:
Network received - The rate at which data is received across the virtual machine’s vNIC (virtual network interface controller).
Network transmitted (Network I/O) - The rate at which data is transmitted across the virtual machine’s vNIC (virtual network interface controller).
NOTE:
If the parent host of the monitored virtual machine is in maintenance mode, this Knowledge Script will not generate events.
Using this script and other VirtualCenter_Vm* scripts to monitor a large number of virtual machines at the same time might cause the jobs to fail. If the jobs fail on a regular basis, consider running the VirtualCenter_Vm* scripts on fewer virtual machines.

By default, this script runs every day at 15 minute intervals starting at 12:09 AM and ending at 11:59 PM. If you start the job after the scheduled starting time, the script runs at the time of the next scheduled interval. For example, if you start the job at 12:10 AM, it runs for the first time at 12:24 AM.
NOTE:If you are running this script as part of the Recommended Knowledge Script Groups, do not change the schedule. The schedules for the recommended scripts are staggered to lessen the impact on CPU utilization when you run the KSG.

Select Yes to raise an event if network I/O metrics are not available. The default is unselected. |
|
Event severity when network I/O metrics are not available |
Set the event severity level, from 1 to 40, to indicate the importance of an event in which network I/O metrics are not available. The default is 15. |
|
Event severity when AppManager failed to get metrics |
Set the event severity level, from 1 to 40, to indicate the importance of an event in which AppManager failed to retrieve metrics from vCenter. The default is 15. |
|
Event severity when AppManager failed to log in |
Set the event severity level, from 1 to 40, to indicate the importance of an event in which AppManager failed to log in to vCenter. The default is 5. |
|
Event severity when VmNetworkI/O job fails unexpectedly |
Set the event severity level, from 1 to 40, to indicate the importance of an event in which the VmNetworkIO job fails unexpectedly. The default is 5. |
|
