Alarms.db is also referred to as the alarms database. Alarms.db is an encrypted binary file that maintains a historical record of all alarm events that have occurred in the system. VTS automatically creates a new Alarms.db database file for each new application you create as soon as the application is initially run, regardless as to whether you have configured any alarms for the application.
Alarms.db contains the last 10,000 alarm events saved, and includes all user-configured alarms for your application.
Alarms.db cannot be customized using configuration file settings.
Further information on the "Alarms.db" database can be found in Alarms.db File.
