Hi Viktor, thanks for the explanation! Viktor Naoumov wrote:
Hi Wilfried,
We cannot display synchronized graphs at the last measurement time position because RRDs are updated only when the measurement data comes from the probe. Probes are allowed to send data not synchronous for all the measurements.
As it implemented currently, we stop the graph at the time stamp of the last measurement. We can do it using current time, in this case graphs will be aligned, but unreceived data will be displayed as a gray area, that's what we do not really want.
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,

Thanks, best regards, Wilfried.

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.
