[Observium] Smokeping integration

Hi,

I have a machine named techops01, I have a directory /opt/smokeping/ that is running smokeping. cache/ has the png files etc. I've tried pointing to both, readding the host, rediscovering, nothing.

Additionally, smokeping does not allow "." in the host name. I saw somebody had a patch for observium to add conversion of '_' to '.' , did this ever make it into code? I haven't seen a flag

### smokeping testing $config['smokeping']['dir'] = "/opt/smokeping/cache/";

also tried

### smokeping testing $config['smokeping']['dir'] = "/opt/smokeping/";

Its not a permissions issue, its 777 now for testing purposes.

Thank you! Morgan
