J’ai fait un petit script en bash pour faire un service Nagios. Le voici à disposition.
Celui-ci utilise streamripper pour dumper le flux audio pendant $DURATION secondes et vérifier que le fichier crée fait au moins $DUMP_LIMIT ko.
Il suffit de lui passer l’url du flux en paramètre.
#! /bin/bash
# This check uses streamripper to dump a continuous audio stream, check if file exists and
# determine if the streaming service is working or not.
