HI Following Problem: Every thing works great but there is only one interesting problem.. sometimes when i want to view a graph i get a blank/grey frame .. and when i moveover i get the timestats but nothing else... so i think, the graph is there.. and when i refresh or switch to another graph and back, ...it works... very strange... I already installed SpeedyCGI but it did not help...... -.- HEEEELPPPP

What exactly do you mean by 'blank grey frame'? Can you post a screenshot? This could be your broswer being unable to download the image, or maybe the graph background is grey only meaning no data available? Are there any error messages in your web server error log? What browser are you using, and what web server, and which versions of routers2 and RRDTool? |

So: routers2 Version : Version 2.18 apache httpd : Version 2.2 rrdtool : Version 1.3 mrtg : Version 2.16.2 I tried it on different hosts with different browsers(inet explorer, firefox) and there arent any erros at the Webserver. Actually it runs... but sometimes there are blank screens... I made 2 screenshots and I hope it will help you understanding my straaaaaaangeeeeee problem^^ edit: And It running all on Vmware Fedora 9 twain |

This is very odd, particularly since the time popup is still working which would indicate that the page javascript has loaded. However there is nothing on the page... It doesn't look like you've done anything to change the CSS or font colours, and in any case the graph image should still appear. Also the popup should only appear when the cursor is over the graph! I'm a bit stumped by this one, but can you please save a copy of the HTML from the centre frame (right-click on the frame and do ThisFrame->ViewSource) and send me that? It may make things clearer. |

*Also the popup should only appear when the cursor is over the graph!* I think the graph is still there.... and there is only the grey frame above the graph... because the time popup only appears on the right point , where the graph actualy should be.

This is the problem: <img width="149540308" alt="Traffic Analysis for lan0 -- SVDB1057" src="/graphs/Epcos.Bizsvdb1057.epcos.biz.cfg-svdb1057.epcos.biz_65539-d-l2.png" name="igraphd" height="2459159" border="0" onmouseover="timepopup(this,'igraphd',530,200,300,1216103100,400,7200)" onmouseout="clearpopup()" onmousemove="mousemove(event)" /> The width and height are completely crazy. These two values are passed from the RRD library but not checked for sanity, and they seem to have gone wild. Everything else appears OK. I think this is an RRDTool library bug of some sort. You mention you are using RRDTool 1.3, and routers2 has not yet been tested with this version of RRDTool, only with 1.2. I think v1.3 is still the 'beta/development' status as well. It may be that the RRDs graph API has changed its return values in v1.3.x as well, confusing Routers2. I can only suggest moving back to RRDTool v1.2.x which should work correctly, or trying to get a more up-to-date version of v1.3.x if you must use v1.3. Steve |

mkay....bit bad... i have already done a lot of work.. i hope there won't be any problems rolling back to 1.2..... Anyway ...its interesting why rrdtool sets the height, width at once.. mostly if i click very fast through the graphs. and when i click on rescale or on any other button it works...and another question..... RRDTOOL passes heigth and width?? I thought routers2.cgi generates this on his own.... maybe i can override the values permanently???????? |

| Post subject: | Re: STRANGE FRAME PROBLEMS ..... |
The size of the graph image can vary depending on the size of the legend, so routers2 relies on the returned values from RRDtool to set the image size in the IMG tag. Probably I can do some sanity checking on these and just omit the height/width options if the returned value is nonsense, but this is a workaround. I'd rather find out why its doing this, as it may be a genuine bug in RRDTool that needs to be reported to Tobi. If you endable debug mode ( debug=yes in the routers2.conf) then you will get extra comments in the generated graph frame giving the entire rrdtool command parameter list (and it can be very long). This would be of help tracking down the problem. |
