[collectd] Antwort: Re: WG: Re: rrdcached/collectd ports

[Stefan.Wiederoder at kaufland.de]

sorry about the late reply, two weeks holiday and other stuff kept me away 
from my collectd POC.

I´ve started from scratch, built a new collectd client (with rrdtool, and 
all his 3rd party libraries) and
now I´m receiving data using the rrdcached and the plugin (CreateFiles 
true)

Escape character is '^]'.

the only thing I´m not sure about are the rrd-files on my central server 
running rrdcached, because
rrdcached will complain if I setup a new host - because he has no data 
files to write to:
        Aug  6 09:31:47 ipmzs02 rrdcached[25924]: handle_request_update: 
stat 
(/opt/collectd/collectd/var/lib/collectd/host.on.somedomain/df/df-import-QPL_lsarch.rrd) 
failed.
do I have to transfer the files initially from my client?

I´m running rrdcached with these options:
/opt/rrdtool_svn/bin/rrdcached -l 4.28.13.30:42217 -l 
unix:/var/run/rrdcached.sock -b /opt/collectd_data -F -j 
/opt/collectd_data/journal -w 60 -F -t 10

I´d grateful about a small rrdcached howto in the wiki, 
Inside_the_RRDtool_plugin is nice to read but
a large scale collectd howto would be really great.

if you set the `CreateFiles' option to `false', only existing files will
be updated by the daemon. Do those files exist?

Could you please provide a PCAP file (the output file format of tcpdump)
of some network traffic between collectd and rrdcached? That way it'd be
easier to understand what's really going on.
