Bug in cacti 0.8.4 - changing graph template

[Guest]

First of all I must say it's a great tool and I use it for some time. Now I installed 0.8.4 and discovered some things:

I created a polling host and then added some graphs with template Interface - Traffic (bits/sec). Ok, next I wanted to change the graph template in Interface - Traffic (bits/sec, Total Bandwidth) - seemed to be ok. But when I looked at the graphs there was some things wrong: the graph won't display and the output of the debug contains:

ERROR: no rrdtool fetch output, you probably forgot to pass a valid data source

Changing to other graph templates works fine, but to Interface - Traffic (bits/sec, Total Bandwidth) don't.

Next I deleted the graphs to create them again but I could't until I deleted the Data Source also, which I don't think is good.

And one more thing: when I delete a host from polling hosts I expect all data sources and graphs associated with it be deleted as well but that is not what is happening. I have to search for Data Sources associated with the host I deleted and remove them.

This thread should be moved to the Unstable Development forum.

I just had a similar experience, where I deleted a polling host, and although it is missing from all drop-down selection lists, the data sources and graphs are left behind and have to be cleaned by hand. I thought this worked in 0.8.3. It does seem broken now.

Additionally, if a deleted polling host had been placed on a graph tree, that remnant must be cleaned up by hand, as well. My recollection is that was always broken.

FWIW I am finally able to switch graph templates at will in the new version without having to fix the graph's data sources -- hooray! I could not replicate the problem switching to "bits/sec, Total Bandwidth."
