Description of problem:

Within satellite 6.13.0, the URI https://satellite_uri/hosts seems to always load the powerstate of the VM via compute ressourse.


- On Satellite 6.13, remove the 'Power' option from the 'Manage columns' option on page Hosts >> All Hosts

- load the page again and check logs showing power fields.

The example below logs:

- However, on Satellite 6.12 if we change the setting for webUI -> Administer -> Settings -> General -> Show host power status. Set it to no, the similar logs do not appear.

- 'Show host power status' is similar to the "Manage columns", power option settings on Satellite 6.13.




Version-Release number of selected component (if applicable):

6.13




Actual results:

- Satellite is checking the power status of hosts from compute resource and delay in loading the 'All hosts' page.


Expected results:

- Satellite should not check the power status if the "Manage columns" > power option is not selected.




Additional info:

- No difference in logs if we unselect or select the power option on Satellite 6.13 however, there was one difference like the 'power' field completely vanished on Satellite 6.12 if we disable the settings.

- Attaching logs from 6.13 and 6.12 Satellite with and without power option selected.

- Customer observed the behavior and reported slow loading performance.
