I need more details on my network state , so I change some query's graph template . Then there comes out problem .
When I change my graph template (Interface - Traffic (bits/sec)) to (Interface - Traffic (bits/sec, 95th Percentile)) , the 95th percentile have no data , when I create a new graph use (Interface - Traffic (bits/sec, 95th Percentile)) template , the data comes out , did I miss anything ?

Any advice ?

Please edit the failing graph from graph management. The bandwidth graph template adds a complex COMMENT statement I want to see

Sorry for my poor knowledge . I didn't find where to edit the graph.

I change my graph template to 95th template then go to graph management , as the picture following , can you tell me where did I do wrong ?

Thanks !!

I was not asking precise enough, but you did it correctly. I only need the lower part of the picture!

Hmm, this requires more analysis on my side.
I _know_ that doing such a change on graph templates causes problems. But I don't know by now the root cause.
Please try the following:
Visit the Graph at Graph management, check it and select "Change Graph Template". Not sure this will help, but it's worth a try

no help...

I have the same problem -- changed graph template to use 95th percentile and only 2 graphs are reflected properly. If I stumble across a fix for this issue I'll post my steps.

During the course of the day some graphs are starting to show 95th percentile -- no changes made, so not sure why it happened but things are starting to get sorted correctly.

Well, only the red line was missing?
Using this graph template, this is unfortunately detected quite often. The HRULE is above the topmost value. rrdtool does not take HRULE into account when autoscaling

Sorry for several days offline .

Yes , just the red line is missing .
After several days away , there still do not come out the 95th percentile on my graph

Oops, I just verified, that the number for 95th is 0. So my approach fails. This must be due to changing the graph template. You may drop the graph, preserving the data sources. Then, please recreate a new one, this time specifying the correct 95th percentile template. Now you may associate the preserved data sources. This way, it should be fine.
Please verify

I have tried this way several days ago , and it really works . The problem is that it is a little hard for me to complete this work , because I have hundreds of pictures

. And I am a lazy guy

Now it seems only this way can get it , I will do .

Thanks for yours help .

I can verify that this worked for me. I was having the same problem...no 95th percentile line, and the legend value for 95th percentile was zero. After following gandalf's procedure above, it's working perfectly.

Thanks, gandalf!
