<span style=" font-family:'Courier New'; font-size: 9pt;">www-data needs rights to write to the RRD files.<br>
<br>
A search for "slave permissions" will probably give a few more pointers from the list since this is a common issue.<br>
changing ownership and rights should set you right.<br>
[Even better, mod'ing the startup script to change all the RRD files so they are www-data writeable - this way new slave setups won't get borked if you forget to mod them...a post in the last day or two showed a good example of this.]<br>

I am pulling my hair out trying to get the slave graphs to update on the master server.<br>
<br>
I have ran the debug on the slave and can it executing the probe and sending the data to the master. apparently the server acknowledges it, but nothing appears on the webpage.<br>
<br>
<br>
This is how the apache and smokeping process run:<br>
<span style=" font-size: 7pt;"># ps -ef | grep apache<br>
root 987 1 0 22:45 ? 00:00:00 /usr/sbin/apache2 -k start<br>
www-data 989 987 0 22:45 ? 00:00:00 /usr/sbin/apache2 -k start<br>
www-data 991 987 0 22:45 ? 00:00:00 /usr/sbin/apache2 -k start<br>
www-data 992 987 0 22:45 ? 00:00:00 /usr/sbin/apache2 -k start<br>
<br>
# ps -ef | grep smokeping<br>
106 1706 1 0 23:05 ? 00:00:00 /usr/sbin/smokeping [FPing]<br>
<br>
<span style=" font-size: 9pt;">There is nothing in /var/log/syslog to suggest why this is not working.<br>
<br>
There is however these in /var/log/apache2/error.log. The problem is that those files don't exist<br>
