Monitors the read (inbound) traffic of a network card on a virtual machine and alerts if the utilization is over the threshold for a specific number of samples.
The read (inbound) traffic on a virtual machine’s network card is high.
The following configuration parameters are customizable:
IntervalSeconds - The recurring interval of time in seconds in which to run the script (the default value is set to 300 seconds).
NumberOfSamples - The number of event occurrences before monitor state changes will be triggered (the default value is set to 3).
Threshold - The value that defines the warning threshold to be used in the comparison (the default value is set to 500 Mbps).
Applications running on the virtual machine may cause an intensive network read activity.
Consider the following solutions to reduce the read (inbound) traffic:
Check whether the read traffic is high for longer periods of time.
Check whether the read traffic is high on individual or all virtual machine’s network cards.
Check what applications are running on the virtual machine.
Check whether you can redirect some of the read traffic to other network cards on the virtual machine.
High read (inbound) network traffic can be a result of a high read activity of applications running on the virtual machine.
