Subsequently, it became necessary to log and record the actual alarms for the current moment. For the alarms logging it is sufficient the formation of system messages with the specified category and message format, but for the monitoring the ongoing(actual) alarms a buffer is needed. Subsequently, a buffer was added as an add-on of the messages subsystem, and its addressing is made by the inversion of the message level. So, the message record with the level "-2" and the category "TEST" will put the message into the alarm buffer and duplicate it in the messages archive, with the level of "2". At the messages request with the negative level they will be taken from the alarm buffer. Deleting/removing of the alarm is made by writing the messages with the same category "TEST" and the non-negative level.
