Measures reported by AWSEc2VmPerfTest

Tracking the CPU usage, disk and network I/O of every instance launched by a configured AWS user account in a region will provide administrators with valuable insights into how well the instances are utilizing the allocated resources. The AWS-ECS VM Resource Usage test does just that. This test auto-discovers the instances available for the configured AWS user account in a region, and reports the resource usage of each instance so that, administrators can quickly compare the usage metrics across instances and pinpoint which instance is resource-hungry.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Cpu_used Indicates the percentage of allocated CPU consumed by this instance. Percent A high value for this measure indicates that an instance is utilizing CPU excessively - this could be because of one/more resource-intensive processes executing on that instance.

Compare the value of this measure across instances to identify the CPU-intensive instances.

Network_in Indicates the rate of incoming network traffic i.e., the rate at which the bytes are received by all the network interfaces connected to this instance. KB/Sec Compare the values of these measures across instances to quickly identify the instance that is utilizing the network bandwidth excessively.
Network_out Indicates the volume of outgoing network traffic i.e., the rate at which the bytes are transferred from all the network interfaces connected to this instance. KB/Sec
Disk_reads Indicates the rate at which data is read from the disks of this instance. KB/Sec These measures are good indicators of the level of disk I/O activity on an instance. By comparing the values of these measures across instances, you can accurately determine which instance is performing I/O-intensive operations.
Disk_writes Indicates the rate at which data is written to the disks of this instance. KB/Sec
Disk_read_op Indicates the rate at which disk read operations are performed on this instance. Operations/Sec These measures are good indicators of the level of disk I/O activity on an instance. By comparing the values of these measures across instances, you can accurately determine which instance is performing I/O-intensive operations.
Disk_write_op Indicates the rate at which disk write operations were performed on this instance. Operations/Sec
Instance_status Indicates whether/not this instance is powered on.   The table below lists the protocols that can be reported by this measure, and their numeric equivalents:

Measure value Numeric value
Off 0
On 1

Note:

By default, this measure reports one of the Measure values listed in the table above to indicate whether this instance is powered on or not. The graph of this measure however, represents the same using the numeric equivalents only.
