The SPLSTATUS file contains log related information for all the objects that are monitored. If the file gets corrupt, then there is a possibility of logs missing or not syncing for a few objects.
Perform the following steps to resolve the logging issue:
Close all the Operations Sentinel applications or instances.
Stop Operations Sentinel server services.
Browse to the LOG folder at <install drive>\ProgramData\Unisys\Operations Sentinel\LOG and locate the SPLSTATUS file.
Delete the SPLSTATUS file.
Start Operations Sentinel server services.
On restarting the Operations Sentinel server services, a new SPLSTATUS file is created at the LOG folder.
