Hi again,<br>
<br>
This is not something I have succeeded with - so you are probably already rendering them in your client/browser.<br>
If this is the case - I don't expect that it would take much effort to display the value as well.<br>
<br>
But I assume that you are not using rrdtool directly to get your graphs today.<br>
What tool are you using? Is it a monitoring-tool that uses rrd for it's storage?<br>

I would say - No, at least not out of the box.<br>
rrdtool can create images of different formats, but as long as they are static images - nothing will happen when you hover over them.<br>
<br>
If you instead use some of the data exports (sending datapoints to the browser) - and render the graph in the browser using some library (JavaScript, Flash, Java, HTML5?),<br>
then you will get the functionality that you are referring to, and can add zoom and other things..<br>
<br>
I don't know if anyone on this list has a functionality like that working already - or know a framework that supports RRD already - but I'm interesting in finding out.<br>
<br>
For a while back I started looking into a layer over RRD so I could get a standardized interface to the data - no matter if it was stored in RRD or some of it "competitors".<br>
But that work never really started - unfortunately, but it would still be nice to know if anyone knows of one.<br>

I am using rrdtool 1.4.8 on centos 7 and using it to graph the output obtained using nagios/nagiosgraph. Now my question, is there a way to display the value under the cursor when mouse is hovered above the graph?<br>
<br>
<br>
(I googled it but could not get the right info, so thought of asking here).<br>
