Requirements based performance monitoring for virtual machine networks

An apparatus measuring performance of an application running in a virtual computer network, comprising:

• in interface receiving, for each device of a plurality of devices in the network, an existing flow of device operating parameters, the device operating parameters comprising an input/output operations (IOPS) rate, device throughput, device latency, and slow input/output (I/O) counts representing I/O operations exceeding one second in duration;
• a processing component measuring a performance for each device and the network as a whole over a plurality of durations for a specified time period in terms of the device operating parameters, analyzing a workload of a primary application of a target device of the plurality of devices in terms of data transfer variables of the primary application to determine an envelope of I/O requirements of the primary application, wherein the envelope is expressed as a three-dimensional set of n tables, and measuring a total amount of data moved in the network for all devices of the plurality of devices over the specified time period;
• and
• a reporting component producing a summary performance score for each device using measured performance and the envelope of I/O requirements to provide an indication of whether or not a required read/write performance of the primary application is satisfied, wherein the performance score is calculated using data variables comprising device throughput, input/output operations (IOPS), device latency, slow I/O counts exceeding one second, average block size, and read-to-write ratio.

A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, the computer-readable program code adapted to be executed by one or more processors to implement a method of measuring performance of an application running in a virtual computer network by:

• receiving, for each device of a plurality of devices in the network, an existing flow of device operating parameters;
• measuring a performance for each device and the network as a whole over a plurality of durations for a specified time period in terms of the device operating parameters;
• analyzing a workload of a primary application of a target device of the plurality of devices in terms of data transfer variables of the primary application to determine an envelope of I/O (input/output) requirements of the primary application, wherein the envelope is expressed as a three-dimensional set of n tables;
• and
• producing a summary performance score for each device using measured performance and the envelope of I/O requirements to provide an indication of whether or not a required read/write performance of the primary application is satisfied, wherein the performance score is calculated using data variables comprising device throughput, input/output operations (IOPS), device latency, slow I/O counts exceeding one second, average block size, and read-to-write ratio.
