Hello,
I found a solution to this problem (at least for me) at
http://emacstragic.net/collectd-causing-rrd-illegal-attempt-to-update-using-time-errors/
I include the full article bellow in case it disapears:
" Collectd causing rrd illegal attempt to update using time errors
I found collectd was giving me a whole load of errors in my syslog:
Aug 20 16:27:12 mythbox collectd[32167]: rrdtool plugin: rrd_update_r
(/var/lib/collectd/rrd/mythbox/df-root/df_complex-free.rrd) failed:
/var/lib/collectd/rrd/mythbox/df-root/df_complex-free.rrd: illegal
attempt to update using time 1345444032 when last update time is
1345444032 (minimum one second step)
It was adding one message like that every second so my logs were
completely full of it. Google didn’t reveal much except that this sort
of error is either because there are two instances of RRD trying to
write the RRD database at the same time, or that my server’s date and
time are way out of sync. Neither of these were true in my case.
I asked on #collectd on freenode and a very nice person by the name of
tokkee told me that it’s a known issue of sorts. The df plugin for
collectd uses /proc/mount to determine which drives to check free
space on and if / is in there twice, it tries to update the entry for
/ twice and causes the problem.
The solution is to add the following to the /etc/collectd/collectd.conf file:
<Plugin df>
FSType "rootfs"
IgnoreSelected true
</Plugin>
Then I restarted collectd and my logs were peaceful again. "
The fun part is that the solution was given by "tokkee".
Is it the same tokkee as Sebastian Harl <tok...@debian.org> maintainer
of this package? :-)
Bye
