<p class=MsoNormal><span lang=EN-US>Hi All!<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I am pretty new to RRD, so please forgive any
overly-newbie question. I did read the doc and googled, but there are a number
of holes and I cannot find the answers I am looking for.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I am developing a dashboard for our company
that contains data from various sources. One is performance data that we write
to RRD. In once RRD file we have the response time for a specific web page.
What I am trying to do is pull out the average response time over the
last hour, last 24 hours and last week and then display the numeric values in
the dashboard. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I can get the 5-minute averages over the
last hour (I think) with this command:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>rrdtool fetch response.rrd AVERAGE -r 300
-s -1h</span><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US> The problem is that I get a list of
values over the last hour as opposed to a single value representing the average
over the hour. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>It would be fairy straight forward to write
something to manually calculate the average based on the data output, but I was
hoping I would not have to re-invent the wheel.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Any input is appreaciated.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Regards,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
