[smokeping-users] master/slave error

[Seth Lyons]

Thanks for your response.  I set the permission accordingly, but I still have the same problem.  The .rrds and slave_cache files are being created, but the graphs are still blank.  I ran a debug on the slave and everything went fine...it ended with "Sent data to Server. Server said OK," and the pings showed the latency I was expecting.
 
If I dump one of the .rrd files to xml and view it in an editor, it is has a small amount of real data at the beginning, but it is mostly full of NaNs.

The directory that holds your RRD files must be readable/writeable by
both the Smokeping process AND the webserver.

e.g.  If
  - Your httpd runs as 'www'
  - Smokeping runs as 'smokeping'
  - In the Smokeping config, datadir  = /var/www/smokeping/rrd

Then,
- Create a new group called 'smokeping'
- Add both the 'www' and 'smokeping' users to that group
- chgrp smokeping /var/www/smokeping/rrd
- chmod -R 775 /var/www/smokeping/rrd

That should clear it up.

If that doesn't work, run one of your slaves with --debug and see if it
spits back an error of any kind.
