Hi,
We have the exact same issue! But it seems sporadic for us.
When we have rrdcached enabled with ‘$config['rrdcached']
= "unix:/var/run/rrdcached.sock";’, the rrdtool command also shows relative locations for the rrd’s.
However the relative path cannot be the problem as it does work most of the time!
Here you can see below, they are both the same (they both use relative paths vs the full path).
I went onto the server and ran the command on the cli ( the one which results in “Error Drawing Graph”, and it works perfectly! The
created .png file is fine ).
Adam, I assume that it is Observium which is building this command string. And I have checked our config.php and I am very confident
it is correct as the only variable which defines any path relating to rrd’s is the above rrdcached one. I cannot even see a variable in the default incudes config.php so not sure where you are getting this path from to help debug this? – But as mentioned the
relative path doesn’t seem to matter.
A Broken Example;

Oh. That explains the truncated filenames.
The issue seems to be related to the rrdtool binary. This is, of course, not written by us! :D
Probably installing a different version of rrdtool will remove whatever the issue is.
