Smokeping under Debian with Master-Slave configuration

Since it happened every time with my master-slave setup that data of new probes does not show up, I am blogging it here for future reference.

Make sure that the Smokeping directory is writable for www-data.

Furthermore make sure that the directories and RRD files in the directories have the correct permissions. When Smokeping creates new RRDs they have wrong permissions!

As soon as the permissions are correct, data starts showing up. As you can see there is a *.slave_cache file since one of the slaves is currently sending data. The file is owned by the Apache process because the master-slave-communication uses the Smokeping CGI.

I hope this helps.
