9.3.2.7. set monitoring-engine

A - Introduction

The `monitoring-engine` command of the `set` sub-group enables applying an advanced configuration for the GCap sensor detection engine.

Note

If the number of signatures loaded by Sigflow is too large, the timeout value must be adjusted.

B - Prerequisites

User: setup
Dependencies: the detection engine must be switched off

C - Command

To change the grace period when starting the engine: `set monitoring-engine start-timeout SECOND`.
To change the grace period when the engine is stopped: `set monitoring-engine stop-timeout SECOND`.
To enable or disable the check of the controls: `set monitoring-engine {disable-sanity-checks|enable-sanity-checks}`.
If the `sanity-checks` option is set to `enable`, the detection engine starts only after verifying that at least one `monx` capture interface has been activated and that a cable is connected.

D - Procedure to change the grace period to 600 seconds when starting the engine
