How To Calculate the Ambiguity Index

Before you can begin managing ambiguity, update the ambiguity index for the existing CIs and CI Transactions. You update the ambiguity index for CIs and CI transactions by running the cmdb_update_ambiguity command.

Important! Run cmdb_update_ambiguity at least once to measure CI or CI transaction ambiguity. If you do not run the command, all ambiguity indexes are 0 (zero), which implies no ambiguity.

You can run the utility before and during ambiguity management. Schedule the utility to run periodically, so the ambiguity indexes reflect the current state of your system.

To use the ambiguity index

  1. Determine the necessary parameters to run the utility.
  2. Run the utility.
  3. Start the CA SDM Web Client and navigate to the Ambiguous CI or Ambiguous CI Transaction Lists to manage the ambiguity.
