I think this is a quirk of RRD.

It's actually quite difficult to get "current" values for stacked graphs in RRD, because sometimes you don't have any measurements for some entities in the "current" timeperiod.

I think in this specific case it's that there are /no/ entries in the "current" time period. This is an issue we've seen for a really long time, it's super annoying.

Some of the Aggregate Bytes Stacked graphs have the sum of the total displayed.

But some do not and show 0 bytes.

Not sure what you mean.

That works now Adam, many thanks.

 

One question; I have noticed that some of the graphs don’t have the totals summarised.

 

 

Any suggestion? Would this be related to missing RRDs?

 

Regards

Do all of the RRDs exist? This happens on one of my groups when one of the RRDs doesn't exist because of a leftover debugging statements.

 

I'll remove it!

Hello,

 

We have a number of Groups of type Storage in order to see the Aggregate Bytes Stacked graph for that set of storage, this has been working well but when creating new groups in r9645 (possible before) the graph is blank / will not display.

 

Any suggestions on diagnosing this would be appreciated.

 

 

Regards
