Hello,
I have checked the .rrd files and I’m sure that no data in .rrd files. This is
why graphs are empty. But .slave_cache files has data and master can’t update
the .rrd files for no reason.
They’ve same rights with other .rrd’s and 12 slaves work without any problem.
You can see the access rights at the below. I’m looking for any advices.
# find . -type f -name '*Gayrettepe.rrd' | xargs stat | grep 666

Subject: Re: [smokeping-users] Master/Slave Data Problem
I haven't read very carefully, but it certainly looks like the "typical" -
can't read or write the RRD's. [Reviewing the logs of smokeping run in debug
mode, and the same for slaves and the web-server will likely be very helpful in
verifying that this is what is occurring. But it's a common problem - one of
the most common I see.]
The master and output/graphing processes run as the user that smokeping is
configured to run as. Thus, if the master can't write to the RRD's or can't
graph them [and there's data in them] then the master smokeping user doesn't
likely have rights to read/write to/from those rrd files.
The slave process writes data, to the rrds on the master, as the web-server
user. [apache, www-data etc] If the slave can't write to the RRD's it probably
doesn't have the proper rights.
For both to work, [master and slave] then both have to have rights. [The
web-server user/group and the smokeping user/group]
Determining the proper group/user(s) to give rights to, and how to do so is
left as an exercise to the reader.

Hello,
I’m using 1 Master and 14 Smokeping Slaves in our network and I’m facing
interesting problems with last 2 slaves. Do you have a suggestion on how to
solve the problem I have detailed below?
Master Smokeping version is 2.006008
Slave Smokeping version is 2.006009 and I have working slaves on both version
(2.006008 and 2.006009)
These Slaves are working on Raspberry Pi 3
First problem is data write problem;
# ls -l | grep Gayret
-rw-r--r-- 1 smokeping www-data 2986808 Mar 31 10:48
garanti~Smokeping-Gayrettepe.rrd
-rw-r--r-- 1 www-data www-data 179 Mar 31 11:17

-rw-r--r-- 1 www-data www-data 173 Mar 31 11:17
superonline.Smokeping-Gayrettepe.slave_cache
As you see on the above I can see the slave server data in the master server
but it is not writing on it.. Last modified time is not being updated. No data
in the graphs anyway
Second problem is similiar;
Again, I can see the slave data in master server it is writing on it but this
time no data in the graph.
