Trailing comma issue in config

[nux]

When debugging an issue with uchiwa not connecting to API, I found out that the lack of a trailing slash in redis.json on the last item caused the connection to redis to fail.

{
"redis": {
"port": 6379,
"host": "localhost",
"reconnect_on_error": false,
"db": 0,
"auto_reconnect": "true"
}
}
vs
{
"redis": {
"port": 6379,
"host": "localhost",
"reconnect_on_error": false,
"db": 0,
"auto_reconnect": "true",
}
}

This happened after updating packages on Debian (Jessie). Debian was updated from 8.3 to 8.4. Not sure if it's related.

This is not an issue in sensu-puppet. With a trailing comma the content of the file is not valid JSON and as such not accepted by sensu, causing it to ignore the configuration and go with the default settings. (grep for "ignored" in /var/log/sensu/sensu-server.log)

To solve your issue, the host needs to be "127.0.0.1" since resolution is broken in 0.23.0 for IPv6.

Please check sensu/sensu#1209
