After upgrade from 10.x to 11.5.3 HF2, configuration fails to load with the following error: 01070734:3: Configuration error: Invalid primary key on monitor_param object () - not a full path 2.
Configuration fails to load.
Configuration contains a user-created monitor (A) that inherits from user-created monitor (B). Monitor A appears first within the configuration files and monitor B does not have a 'destination' attribute.
Re-order monitors such that Monitor B appears first, or add a 'destination' attribute (i.e., 'destination *:*') to monitor B.
10.x upgrade now completes successfully, even when parent monitors appear later in the monitor list, or when there is no destination attribute in the child monitor.
