The code for the Health center tool is currently available from the Plugins directory.
The health center is a tool for detecting miscellaneous problems on your site. There is no link to it from the administration block as the tool is not currently maintained, however it may be accessed by browsing to the URL yourmoodlesite.com/admin/tool/health/.
Warning: The health center tool is no longer maintained, and may give misleading results due to not taking into account lots of things it should. See comments in MDL-35212 for further details.
