"Graph was not created!

Probably, no data is available for the requested time period.

RRD: /var/www/htdocs/router2cgi/graphs/to-sw01/to-sw01_14.rrd
Device: [to-sw01.cfg] TO-SW01 Branch Switch , Tok
Interface: _to-sw01_14I-IE"

I believe that these are the graphs taht would have no data in them ie: empty graphs .
I am using "routers.cgi*Options[_]: active" in all my .cfg's & the items showing these messages are those that would not create a graph . Have just verified by moving back to 2.18b5 , this issue is not there .

See attched config .[attachment=0]cp-sw01.txt[/attachment]

Initial thoughts are that, with the active option, no lines at all qualify for the graph and so nothing can be drawn. The checks for valid userdefined graphs were tightened in 2.19 and this may be why you managed to get an empty graph in 2.18b5 and an error now - I think it has to find at least one OK and none bad...

I will look into this and see if I can deal with this special case.

Is there a way to diagnose which items are failing , Using 2.18b5 ?

If you enable debug mode in the routers2.conf then you should get a huge comment in the generate HTML revealing the actual RRDTool function call parameters. This would be of great help to me.

I'll also investigate the logic in the code.

Ok , debug = 1 .

where is the generated html supposed to appear ?

none of my user defined graphs seem to show anything other thatn their normal output .

tia, JimL

Fyi , This is not the rrd pull for one of the erroring graphs . I'd have to copy the new .cgi over to being active for that .
Do you want output like below for one of the erroring graphs ?

I hope this is part of what you are looking for ...

That's the thing I'm after. It should be in the HTML on the crentral (graph) frame, even if no graph is created.

I've checked the code: this is the message which appears if the call to RRDgraph completes without error, but no graph image is created. This should be impossible - if RRDTool fails to create an image, it is supposed to set the error status to explain the reason.

Oddly, this part of the code has not been updated.

One remote possibility is that there are backstrokes in the filename (unlikely as you use unix).

Another possibility is that the new 2.19 is using RRDTool options which are not available in your version of RRDTool. Can you tell me which version you are running? There are several checks in the code to disable certain parts for older versions of RRDTool but some may have been missed out. If it is v1.0.x then you should upgrade to 1.2.x in order to get better image rendering in any case.

If you can give me the debug comment output it will help to track this one down.

Steve , Tho if I click on the 'Error' for that interface I do get a graph , Please see attached file with full webpage of that graphed item that is erroring .
