Changing data source for a graph

[Finbar Saunders]

We are re-patching our main switch to tidy it up a bit. This will mean that the data source for each graph will need to be updated to reflect the new interface that it is on. I've tried to do this for one graph and found that all the previous graph information gets lost and I am left with a new graph. Is there a way to update the data source and retain the history/data for a graph.

Thanks,

Finbar

I've done this several times (to standardize RRD names for Nagios to read). Make sure that you copy the existing RRD file to the new name, and that it's owned by the cacti user. I haven't had a problem yet.

Thanks Leeg!

This did the trick for me.

Hello leeg.

Could you expand on this a bit? How do you have Nagios read the RRD names? I'm very interested in this functionality.

Thanks

Are you just rename graph or you change (recreate) device setting under Data Sources (Devices)? If just rename it's not obviously who is who and what to what rename......
