$ perl centreon_plugins.pl --plugin=apps/protocols/http/plugin.pm --mode=collection --config=/root/test-boolean.config --constant='hostname=127.0.0.1'  --constant='port=80' --constant='critical=1' --verbose
CRITICAL: interruptor '2' switch enabled: 1 | '1#interruptor.enabled.count'=0;;;; '2#interruptor.enabled.count'=1;;;;
interruptor '1' switch enabled: 0
interruptor '2' switch enabled: 1

JSON file provided by the http server:

{ "interruptor": [
        {
            "name": "1",
            "enabled" : false
