[collectd] rrdc_update failed with status -1

[Stian Øvrevåge]

Hi,

When trying to use DaemonAddress "127.0.0.1:42217" I'm receiving

Mar 26 20:52:25 collectd-new collectd[13065]: Filter subsystem:
Built-in target `write': Dispatching value to all write plugins failed
with status -1.
Mar 26 20:52:25 collectd-new collectd[13065]: rrdcached plugin:
rrdc_update (/opt/collectd/var/lib/collectd/rrd/no-kvh020-sw01/snmp/if_drop_discard_err_que-Vlan1309.rrd,
[1332787945:0:0:0:0], 1) failed with status -1.

For ALL updates.

This is my rrdcached plugin config:

<Plugin "rrdcached">
  #DaemonAddress "unix:/tmp/rrdcached.sock"
  DaemonAddress "127.0.0.1:42217"
  DataDir "/opt/collectd/var/lib/collectd/rrd"
  #CreateFiles true
  #CollectStatistics true
  StepSize 30
  HeartBeat 600
  RRaTimespan 3600
  RRaTimespan 86400
  RRaTimespan 604800
  RRaTimespan 2678400
  RRaTimespan 166224000
</Plugin>

I run rrdcached with "/opt/rrdtool-1.4.7/bin/rrdcached -f 7200 -w 3600
-z 900 -b /opt/collectd/var/lib/collectd/rrd/ -l 127.0.0.1 -l
unix:/tmp/rrdcached.sock"

The reason I want to test using network sockets is that the unix
sockets seem to cause thousands of disk reads and writes according to
VMware disk statistics.

A tcpdump with ascii decode only shows this: (No data? And statistics
which I thought I disabled?)
