[rrd-users] rrdtool update error

[Stephen S. Disbrow]

Hi,
Here's all the info, please let me know if any further information is 
required. Also I don't think I'm setting any rrdtool specific variables in 
the environment.

12/02/2009 10:19:13 AM
The rrdcached process is run as the metis user.
all the rrdtooll commands are run as the metis user.
The rrdcached startup command line
METIS_HOME="/usr/local/metis"
BASEPATH=${METIS_HOME}/db/rrd
/usr/pkg/bin/rrdcached -l unix:/tmp/metis.rrd.sock -w 60 -p 
/tmp/metis.rrd.pid  -t 5  -j ${BASEPATH}/journal
-b ${BASEPATH} -B
These files are in /tmp
-rw-r----- 1 metis metis 6 Dec  1 12:26 metis.rrd.pid
srwxrwx--- 1 metis metis 0 Dec  1 12:26 metis.rrd.sock
The $BASEPATH path is on an NFS file system.
The update command is as follows;
/usr/pkg/bin/         rrdtool update  --daemon unix:/tmp/metis.rrd.sock
${BASEPATH}/volumes.rrd N:$accesses:$reads:$writes    &
The error is;
ERROR: rrdcached: Permission denied
The rrd file in question perms are as follows;
-rw-rw---- 1 metis metis 438480 Dec  1 13:25 volumes.rrd


Thanks in advance,
Stephen Disbrow

I suppose, you are connecting to rrdcached through a UNIX socket (see
the -l command line option). In that case, the user doing rrdupdate
needs (filesystem) write permissions for the appropriate socket file.

If that is not the case, please provide more information about your
setup. What rrdcached command line options do you use? Does rrdcached
run as root? Which user is doing the rrdupdate? What is the command line
used for that (please note that some environment variables might
overwrite some of those options -- see the appropriate manpages for
details)? ...

HTH,
Sebastian
