Hi, we're currently trying to restore RRD databases after having had a disaster on the machine that we run pnp4nagios on.
To get back on track quickly we got our Nagios and pnp4nagios set up before getting to recover the data (the backup server was identical to the Nagios server at that time ...). We're now facing the issue that although the RRDs are similar in structure there seems to be no way to re-integrate the old RRDs' data into the new ones. We'd like to do that so that we only show a few hours gap instead of days. I tried various tools that are floating around (the perl thingy doesn't seem to work at all and I bashed away at rrd-merge-py but that didn't lead anywhere either as I don't have a deep understanding of the data formats involved). As the documentation and Google are also pretty silent: is there a story that I'm missing about restoring and merging data from a backup into a (compatible) RRD that already started storing new data? I'm providing two sample RRDs for your inspiration and any help or pointer would be appreciated: http://shared00.gocept.net/~ctheune/ping_new.rrd http://shared00.gocept.net/~ctheune/ping_old.rrd Cheers, Christian -- Christian Theune · [email protected] gocept gmbh & co. kg · forsterstraße 29 · 06112 halle (saale) · germany http://gocept.com · tel +49 345 1229889 0 · fax +49 345 1229889 1 Zope and Plone consulting, development, hosting, operations _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
