ID: 4100 Title: mk_mysql: Only perform queries if mysqladmin ping is successful# Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.4.0i3 Previously, a dead MySQL daemon would lead to the mk_mysql plugin causing high server load. This has been fixed by performing the more detailed queries only if the mysqladmin ping is successful. Thanks to Evy Bongers for this patch.
