So I am working on upgrading a number of things right now to collectd 4.10.2 and rrdtool 1.4.5. Unfortunately one of my major problems, is still around. When rrdcached dies/stops and then gets restarted, collectd will not reconnect. There was a discussion of this on IRC at some point, but I never got back to do more testing. Even with the latest version of rrdtool on client and server, collectd will go into a spin with messages like:
Dec 29 23:45:40 appbuild01 collectd: collectd startup succeeded
Dec 29 23:49:00 appbuild01 collectd[10338]: rrdcached plugin: rrdc_update (appbuild01.autc.com/cpu-0/cpu-user.rrd, [1293695340:49451049], 1) failed with status -3.
Dec 29 23:49:00 appbuild01 collectd[10338]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1.
Dec 29 23:49:00 appbuild01 collectd[10338]: rrdcached plugin: rrdc_update (appbuild01.autc.com/cpu-0/cpu-nice.rrd, [1293695340:28472], 1) failed with status -3.

At this point I have to restart collectd and everything will be fine. The pain is having to do this on > 300 machines.

Hi,<BR>
<BR>
are u directing all 300 machines to same rrdcached server ? Wouldn't it be better to put collectd with rrdcached and network plugin (set up to act as server) enabled on machine that is collecting data, and just use network plugin to send data to that machine on all other machines ?<BR>
