[Issue] Show customer_grid indexer as green when realtime

[m2-assistant]

This issue is automatically created based on existing pull request: #34557: Show customer_grid indexer as green when realtime

---

Description

Magento recommends that all indexers be set in schedule mode ("Update by Schedule") except for customer_grid which should be in realtime mode ("Update on Save"). This is documented here in the devdocs and the Site-Wide Analysis Tool reports this also.

Currently Magento renders all indexers as 'green' when they are in schedule mode, including customer_grid. This is misleading as the customer_grid is not in the recommended state when set as schedule and shows in 'red' when in realtime mode which is its recommended state.

This pull request makes the colours match the recommended state for each indexer.

Manual testing scenarios

1. Set all indexers as realtime with: php bin/magento indexer:set-mode realtime
2. Observe colours for each indexer in admin (System -> Tools -> Index Management)
3. Set all indexers as schedule with: php bin/magento indexer:set-mode schedule
4. Observe colours for each indexer in admin (System -> Tools -> Index Management)
5. Set the customer_grid indexer as realtime with: php bin/magento indexer:set-mode realtime customer_grid
6. Observe colours for each indexer in admin (System -> Tools -> Index Management)

Questions or comments

I have made the function which determines the preferred mode public to allow for extensibility with plugins.

Should the Design Config Grid indexer also be in this category of 'prefer realtime mode'?

Hi @fredden ,
Thank you for reporting and collaboration. Verified the behavior on Magento 2.4-develop instance and is reproducible. But however this is existing behavior of Magento as per Magento Docs screenshot. Existing behavior: Mode: "Update on Save" will be marked in Red and "Update by Schedule" in green for any indexers. Any indexer that requires re-index(including customer grid), status will be changed to "Reindex required" in red color regardless of the mode set. But as per Magento devdocs "Update by Schedule" does not support the customer_grid indexer. Agreed that this change would bring better user experience and hence we considering this as feature request.
Thank you.
