Description

I have observed that the Site Health Status widget on the admin dashboard sometimes displays an incorrect or inconsistent number of issues.

When I log into the dashboard (on several different WordPress sites), the Site Health Status widget will often say "Take a look at the n items on the Site Health screen" where n is typically 5 or even 6. When I click on the Site Health screen and give it a moment or two to run, the number of issues shown is usually no more than 1 or 2 (generally trivial things, like not having a default theme). Once I've visited the Site Health screen and given it time to load, the dashboard widget will generally update to display that same number. However, if I don't, the widget will continue to display the incorrect total.

My very tentative theory is that this might be a processing speed issue. My sites use shared hosting, so they can be laggy. I wonder if perhaps areason for this behavior could be that certain Site Health tests are not completing within a specified interval and that is causing the widget to list those tests as failed rather than incomplete. However, I don't know enough about how the Site Health processes work to judge how likely that may be.

Hi @ate-up-with-motor. Thanks for opening this ticket. Yes, I've noticed this behavior also in the dashboard widget, and on the "Site Health" page.

I also believe that the slight lags noticed in the number display is due to calculations being performed before the display (although I doubt that's the only cause).

For example on the dashboard widget, from https://github.com/WordPress/wordpress-develop/blob/master/src/wp-admin/includes/dashboard.php#L1790 to L1806.

On the "Site Health" page I don't think it's really a problem because correct numbers load after a second or two. But it is an issue on the admin widget because it usually takes several refresh and much more time to get the correct numbers.

I concur. On the Site Health page itself, while it's still calculating, it displays the message "Results are still loading… " until it's finished, after which it displays correctly. Even if it's a bit laggy on a slow or heavily loaded server, there's little ambiguity about what it's doing. The widget is more of an issue because it doesn't appear to finish calculating itself -- even after returning to the main dashboard several times after performing other tasks, it will often still show its preliminary, high estimate of 5 or 6 issues.

One concern with the high false positive number the widget sometimes displays is that if an administrative user becomes accustomed to it, they may tend to ignore the widget and thus be slow to recognize when the Site Health monitor has really identified a real problem. This has already happened to me a few times; I had a new issue (luckily not a severe one -- a stalled cron job) that had persisted for several days because I assumed the Site Health widget was crying wolf again. That's unfortunate because it tends to reduce the effectiveness of this useful functionality.
