[rrd-users] Possible to test for existence of a remote rrd file?

[Steve Shipway]

If you are using the trunk version of rrdcached, then you can do a remote info request.  I don’t believe this will work with the 1.4 stable version though.

[root at kaoru sysconfig]# export RRDCACHED_ADDRESS=mrtg.auckland.ac.nz
[root at kaoru sysconfig]# /u01/bin/rrdtool info foo.rrd
ERROR: rrdcached: No such file: /u01/rrdtool/foo.rrd.
[root at kaoru sysconfig]# /u01/bin/rrdtool info zmdbdev.its-load.rrd 
filename = "/u01/rrdtool/zmdbdev.its-load.rrd"
rrd_version = "0003"
step = 300
last_update = 1331853826
header_size = 2764
