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
It sounds like a permissions issue.
How much time have you spent trying to make sure permissions are correct?
[It sounds like you know what you're doing, but this is a common issue and
virtually always it runs down as a permission issue. My apologies if that
doesn't fit your case, but it sure sounds likely.]
The master RRD's need to be able to write to the files/directory as whomever
smokeping is running as.
The slave RRD's need to be writeable as whatever web-server you're using is
running as. [Apache]
[To *write* the data from smokeping/fping et al.]
Both need read access for the web-server/apache. [To *display* the graph data.]
I don't recall exactly what users those typically are for Ubuntu 14 - but
double check.

Quick, note if the RRD's are getting their time-stamps updated as new data
should get written. If not, you've got a write problem.
If they are, you've got a read problem.
I have no idea why the permissions would have changed though.
