The self-diagnostics service collects the information about the system metrics and checks the operation of all Axxon One components. The data obtained are compared with the indicators of the normal operation of the system. When deviations occur, system health alerts are generated, which can be tracked in the web interface (see 자가 진단 서비스에서 메트릭 보기).

Examples of errors that are tracked:

Out of RAM.
Camera is connected but does not send data.
No events from a detection tool.
Archive doesn't work.
The frame rate is 0 when recording to the archive.
No video is recorded on detection.
Any internal errors of Axxon One.
Out of system disk space.

The self-diagnostics service has the following rules for cleaning the system disk:

Free memory remaining	Cleanup mechanism

< 15 GB	All events older than one week are deleted
