DifferenceCalculation.xml

The DifferenceCalculation.xml file is used to:

  • Find the difference between the cloud topology model on the third-party cloud provider and BMC ProactiveNet. For example, difference when VMs are added or deleted, difference during the tenant organization, and so on.
  • Compare the cloud topology in BMC ProactiveNet with the infrastructure in the third-party cloud provider to find out the modification in the cloud system.

The difference must be calculated on every restart of the BMC ProactiveNet cloud integrator because the possibility of the cloud topology being changed occurs during the down time of the cloud integrator.

Sample DifferenceCalculation.xml file

The following is a sample of the DifferenceCalculation.xml file when BMC ProactiveNet is integrated with VMware vCloud Director.

This file should be used to specify context for difference calculation. Adapter author should specify information by which topology
for specific cloud can be fetched from BPPM in order to do difference calculation.
