<span style=" font-family:'Courier New'; font-size: 9pt;">So, it looks like Apache doesn't have rights to create the cache directory.<br>
<br>
See:<br>
<span style=" font-family:'times new roman'; font-size: 10pt;">drwxr-xr-x 2 smokeping www-data 4096 Jul 1 14:28 .<br>
drwxr-xr-x 6 smokeping www-data 4096 Jul 1 14:28 ..<br>
<br>
<span style=" font-family:'Courier New'; font-size: 9pt;">So, assuming I'm right:<br>
chmod g+w <span style=" font-family:'times new roman'; font-size: 10pt;">:/var/lib/smokeping/Local<br>
<br>
<span style=" font-family:'Courier New'; font-size: 9pt;">This would make that directory RW for the group [www-data]<br>
<br>
However, I'll be surprised if the slaves can write to the RRD's either, since they're also r-- for the group, so you'll probably want to use the same chmod command on them.<br>

root@smokeping-master:~# ls -al /var/lib/smokeping/Local/LocalMachine.smokeping-slave1.slave_cache<br>
ls: cannot access /var/lib/smokeping/Local/LocalMachine.smokeping-slave1.slave_cache: No such file or directory<br>
<br>
If I run it in this way I got the following output:<br>
