[collectd] collectd: rrdcached plugin: rrdc_update failed with status -1

[Yves Mettier]

Hello,

Please provide the version number of the collectd you are using. 
Sometimes, it helps.

For what I can say now, I think that you should not use both rrdcached 
and rrdtool.
If you use rrdcached, do not forget to add "CreateFiles true".

Also check that collectd (and rrdcached if you are using it) has the 
permissions to go to /var/lib/rrdcached/db/collectd and then to write 
files there.

More info here :
  
  
  
  
  
  
  
  
  
llectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_rrdcached
https://collectd.org/wiki/index.php/Plugin:RRDCacheD (this one should be 
updated)


Regards,
Yves
