Situation
When OVORB retrieves alarms from HP NNM server, the Correlation count is not included in the properties list. What is shown in the NNM browser is calculated through the ECS engine with the algorithm kept internal.
BSM NNM Adapter collects all alarms and based on its internal events, calculates the correlation count based on how many times this alarms has been related to the other alarms. So the mechanism may be different from what is done inside NNM browser. Therefore, so is the number.
Resolution
Rely on the adapter number, not the NNM Browser number.
