Currently JIRA DC doesn't have a Lucene health-check (it was removed as part of JRASERVER-65321). As a consequence of that, JIRA Admin is missing some information :
if index is corrupted
Issue last update status
Number of issues in index
We recently introduced new REST API (see JRASERVER-65321) to expose JIRA index status. We can reuse it in Support Tools plugins for health-check.
Call REST API manually, see JRASERVER-65321
