Monitors the read (inbound) traffic of a network card on a server and alerts if the utilization is over the threshold for a specific number of samples.
The read (inbound) traffic on a server’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).
The read (inbound) traffic on a server’s network card can be high for many reasons, including:
Reading activity from the shared storage may be high.
Virtual machines 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 network cards.
Check whether the read traffic is related to a specific virtual machine or is a cumulative result of all virtual machines.
Check whether you can redirect some of the read traffic to other network cards on a server.
High read (inbound) network traffic can be a result of a virtual machine activity or a server activity when reading from the shared storage.
