To mitigate this issue, shorten the data collection and presentation time in Aria Operations by utilizing the Aria Operations Management Pack for Horizon.

1. ​​​​​​SSH to the VMware Aria Operations primary node as root.
   
   Note: If you do not know, or have forgotten your root password, refer to How to reset the root password in VMware Aria Operations (2001476).
    
2. Using vi, edit the /usr/lib/vmware-vcops/user/plugins/inbound/vrho-adapter/conf/vrho.properties.

vi /usr/lib/vmware-vcops/user/plugins/inbound/vrho-adapter/conf/vrho.properties

3. Modify the resourceCollectionInnerThreadPoolSize from default value of 5 to 15 on all the nodes in the cluster.
    
4. save the file.
    
5. Perform steps 1-4 on all other nodes of the cluster including remote collectors or cloud proxies. 
    
6. Stop/start the collection on the Horizon adapters.

Note: if the Horizon mgmt pack is upgraded or reinstalled, the vrho.properties file will get overwritten, and the above steps will need to be performed again.
