[collectd] errors with Filter subsystem: Built-in target `write'

Tue Mar 18 04:03:17 CET 2014

Hi Jesse,

OK, shiny new 1.48 installed ... no change.
What I have tried.

# Explicitly set write target:
<Chain "PostCache">
                <Target "write">
                                Plugin "rrdcached"
                </Target>
</Chain>

No change ... apart from "Dispatching value to all write plugins" changing to "Dispatching value to 'rrdcached' plugin failed with status -1"

Notes that the rrdc_update always fails the same test for every machine. Currently that would be tcp_connections, but before I commented it out,
It was the df (disk free) test that was failing on every server.

It does not seem to stop the graphs being created, just fills the error log.

Interesting,

I am running rrdtool 1.4.8 (compiled afresh) and collectd 5.4.1 (compiled afresh also) on Ubuntu Precise 12.04.

Perhaps it's to do with the version of rrdtool. Which version of rrdtool is your rrdcached using, Andrew?

I'm seeing this too,  I have tried mixing and matching different versions. 5.0.3, 5.1.0, 5.4.1. Recompiled my own collectd rpms. No change.
I'm down to trying another version of rrdtools (the one I'm using is off rpmfind.net<http://rpmfind.net/>, Rrdtools 1.4.7-1.el6.rfx.x86_64.rpm)

I only seem to get this when I run rrdcached, when running rrdtools plugin the logs are quiet.

Did you work this out David?

I'm seeing the same thing on a test collectd 5.4.1 server I've just set up.

The server is busy (>500 packets per second arriving on it) and there are heaps of these errors being logged.

Anyone got any ideas?

Eg:

Mar 17 22:01:31collectd-03 collectd[16278]: uc_update: Value too old: name = foo.example/snmp/if_packets-FastEthernet0_22; value time = 1395054090.000; last cache update = 1395054090.000;
Mar 17 22:01:31collectd-03 collectd[16278]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1.

I am using the v5 upgrade target. All the clients are version 4 of collectd, or SSC Serv.

hello
i've installed collectd 5.4
everything run fine except i get a lot of error like these from some clients

i've checked that collectd is not running twice
also ntp is running on both server & client and in sync

i'm not using rrdcached

my rrdtool config looks like this :

LoadPlugin rrdtool
<Plugin rrdtool>
       DataDir "/var/lib/collectd/rrd/"
       CreateFilesAsync false
       CacheTimeout 120
       CacheFlush   900
       WritesPerSecond 50
</Plugin>
<target "write">
plugin "rrdtool"
</target>

any clues anyone?
