[smokeping-users] RRD files being created, but the graphs are not updating

[Kevin]

This was a working distributed environment with 8 slaves, all running on
14.04 with smokeping 2.006008.

Had a reboot of the smokeping master this am and have had crazy problems
ever since. As part of the troubleshooting for this, we upgraded the master
to 2.006011

Cannot display graphs, even the master tests. In the directories, the
.slave_cache files are being created. But, the corresponding rrd files are
not being updated.

The smokeping_secrets file is really strange now. Before it was 600
smokeping:smokeping and everything worked. After the update, once the
master process is up, I have to set it to 640 smokeping:www-data to get the
slaves to connect. Otherwise I get this error on the slave:





** Starting latency logger daemon smokeping    WARNING: Opening secrets
file /etc/smokeping/smokeping_secrets: Permission denied    ERROR: we did
not get config from the master. Maybe we are not configured as a slave for
any of the targets on the master ?       ...done.*

Any ideas what is going on, or where I can look? The lack of graphs from
the master is really confusing

Apache is Apache/2.4.7
RRDTool is 1.5.5
