vmware probe 6.7x and earlier publishes discovery inventory i.e probe_discovery subject over nimsoft BUS upon every polling.
There are additional keys as below to minimize BUS impact and optimize the discovery performance
Optimize Publishing for the Discovery Server Version
Follow these steps:
In IM / Admin Console, select the vmware probe.
Click Raw Config.
Add or find the key: discovery_server_version.
Click Add Key.
Select the key.
Double-click the Value field, enter the version for your discovery_server.
For example: 8.5
Restart the probe.
Optimized publishing is now enabled. The vmware probe publishes only the delta values for the data it sends to the discovery_server.
Note:From vmware probe 6.82 onwards partial graph is enabled by default.So bus impact has been minimized out of the box and discovery performance optimized.
