Hi Viktor, thanks for the explanation!

I agree :-) > From your email I can guess that you are fetching graphs for your own page. No, not yet. I was looking at the various graphs in the pop-up tabs for my probe. Thus I noticed that the time periods for those graphs were different. > In this case you can set the end time which ever you want: > > http://atlas.ripe.net/atlas/rrd.png?prb_id=3&msm_id=1001&type=minutely&*end=now* OK, thanks for this. Is there a description somewhere? prb_id is obvious :-) but which valuess are valid for msm_id? I presume I can guess the values for type... > or even allow it to be, for example, 15 minutes older: > > http://atlas.ripe.net/atlas/rrd.png?prb_id=3&msm_id=1001&type=minutely&*end=now-15min* > > > now is UTC :-) > Best regards, > > /vty Thanks, best regards, Wilfried. > On 03/30/2011 04:06 PM, Wilfried Woeber, UniVie/ACOnet wrote: > >> I just noticed that the various graphs for the "last 2 hours" display >> seem to be based on different clocks or update cycles (delta = some 25m). >> >> Should these graphs be "synchronised"? >> >> From a UI-perspective it would certainly be a bonus to have them >> aligned, >> at least for one probe. >> >> All the best, >> Wilfried. >> > >
