<html><head><title>Re: [smokeping-users] Master/Slave Data Problem</title>
</head>
<body>
<span style=" font-family:'Courier New'; font-size: 9pt;">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.]<br>
<br>
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.<br>
<br>
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. <br>
<br>
For both to work, [master and slave] then both have to have rights. [The web-server user/group and the smokeping user/group]<br>
<br>
Determining the proper group/user(s) to give rights to, and how to do so is left as an exercise to the reader.<br>

<br>
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?<br>
<br>
Master Smokeping version is 2.006008<br>
Slave Smokeping version is 2.006009 and I have working slaves on both version (2.006008 and 2.006009)<br>
These Slaves are working on Raspberry Pi 3<br>
<br>
First problem is data write problem;<br>
<br>
# ls -l | grep Gayret<br>
-rw-r--r-- 1 smokeping www-data 2986808 Mar 31 10:48 garanti~Smokeping-Gayrettepe.rrd<br>
-rw-r--r-- 1 www-data www-data 179 Mar 31 11:17 garanti.Smokeping-Gayrettepe.slave_cache<br>
-rw-r--r-- 1 smokeping www-data 2986808 Mar 31 10:48 hurriyet~Smokeping-Gayrettepe.rrd<br>
-rw-r--r-- 1 www-data www-data 179 Mar 31 11:17 hurriyet.Smokeping-Gayrettepe.slave_cache<br>
-rw-r--r-- 1 smokeping www-data 2986808 Mar 31 10:48 superonline~Smokeping-Gayrettepe.rrd<br>
-rw-r--r-- 1 www-data www-data 173 Mar 31 11:17 superonline.Smokeping-Gayrettepe.slave_cache<br>
<br>
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<br>
<br>
Second problem is similiar;<br>
<br>
Again, I can see the slave data in master server it is writing on it but this time no data in the graph.<br>
<br>
# ls -l | grep Trabzon<br>
