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 computer program product for monitoring performance in a networked environment, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a hardware computer device to cause the hardware computer device to:

automatically adjust, by the hardware computer device, a monitoring threshold based on a virtual machine being migrated from a first host to a second host,

wherein the adjusting comprises determining a multiplier based on a comparison of the first host to the second host,

wherein the adjusting comprises determining an adjusted monitoring threshold by multiplying an initial monitoring threshold used with the first host by the multiplier.

2. The computer program product of claim 1, wherein the adjusting comprises determining an adjusted monitoring threshold value for use with the second host based on:

(i) an initial monitoring threshold value used with the first host, and (ii) a comparison of performance characteristics of the first host to performance characteristics of the second host.

3. The computer program product of claim 2, 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;

or I/O performance.

4. The computer program product of claim 1, wherein the virtual host is a website server and the network environment is a cloud environment.

5. The computer program product of claim 4, wherein the first host is a first cloud computing node and the second host is a second cloud computing node in the cloud environment.

6. The computer program product of claim 1, wherein the multiplier is a ratio of first and second vectors that quantitatively describe the respective performance of each of the first and second hosts.

7. A computer program product for monitoring performance in a networked environment, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a hardware computer device to cause the hardware computer device to:

automatically adjust, by the hardware computer device, a monitoring threshold based on a virtual machine being migrated from a first host to a second host,

wherein the adjusting comprises determining a multiplier based on a comparison of the first host to the second host,

further comprising;

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

determining, using the hardware computer device, a second metric based on the virtual machine being migrated from the first host to the second host,

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.

8. The computer program product of claim 7, further comprising generating an alert when a measured performance of the first host exceeds the first metric.

9. The computer program product of claim 7, further comprising generating an alert when a measured performance of the second host exceeds the second metric.
