Abstract

Approaches for monitoring performance in a networked environment are provided. An approach includes monitoring, using a first metric, performance of a first host running a virtual machine. The approach also includes determining, using a computer device, a second metric based on the virtual machine being migrated from the first host to a second host, wherein the second metric is a function of: (i) the first metric and (ii) a comparison of the first host and the second host. The approach further includes monitoring, using the second metric, performance of the second host running the virtual machine.

Claims

1. A method for monitoring performance in a networked environment, comprising:

monitoring, using a first metric, performance of a first host running a virtual machine;

determining, using a computer device, a second metric based on the virtual machine being migrated from the first host to a second host, wherein the second metric is a function of;

(i) the first metric and (ii) a comparison of the first host and the second host; and

monitoring, using the second metric, performance of the second host running the virtual machine, wherein

the first metric is a first threshold value associated with a performance aspect of the virtual machine; and

the determining the second metric comprises;

determining a multiplier based on a comparison of performance characteristics of the first host and performance characteristics of the second host; and

multiplying the first threshold value by the multiplier.

2. The method of claim 1, wherein the comparison of the first host and the second host is a comparison of performance characteristics of the first host to performance characteristics of the second host.

3. The method of claim 1, further comprising generating an alert when at least one of:

actual performance of the first host violates the first metric, and actual performance of the second host violates the second metric.

4. The method of claim 1, wherein the virtual machine is a website server.

5. The method of claim 4, wherein:

the performance aspect of the website server is response time;

the first threshold is a first threshold value of response time; and

the second threshold is a second threshold value of response time.

6. The method of claim 1, wherein the performance characteristics of the first host and the performance characteristics of the second host are associated with at least one of:

network hops;

network latency;

CPU performance;

memory performance; and

I/O performance.

7. The method of claim 1, wherein the first host and the second host are separate cloud computing nodes in a cloud computing environment.

8. The method of claim 1, wherein a service provider at least one of creates, maintains, deploys and supports computer infrastructure that includes the computer device running the monitoring engine.

9. The method of claim 1, wherein steps of claim 1 are provided by a service provider on a subscription, advertising, and/or fee basis.
