[rrd-users] Re: time...

[Geert van der Ploeg]

Every error says that the last update-time is exactly the same time as the
time of the failed attempt.

Maybe there's something wrong in your script that triggers every update
twice (and thus, when you have a 'fast' script, this will cause the second
update to be at the same time).

If this is not the cause, you can try to:

 - Print _every_ update-attempt in your script, to see whether you know
about them all.
 - do a rrdtool dump of the rrd-file which is causing these errors, and
check the 'last-update' time.

The 'rrdtool dump' is a powerful tool to debug your rrd-files!

Hope this helps.
