Hi Yannick,<br>
<br>
Will give that a go tomorrow.<br>
<br>
Steve Shipway has come up with another solution off-list, and that
seems to be approximately what I wanted - but you make a valid
observation, and I will need to fix that.<br>
<br>
Regards,<br>

I think it's cause by this line :<br>
<pre class="line-pre"><div class="line" id="file-gistfile1-txt-LC36">CDEF:ds4ak=ds4a,UN,0,ds4a,IF </div><div class="line" id="file-gistfile1-txt-LC37">CDEF:ds4bk=ds4b,UN,0,ds4b,IF </div><div class="line" id="file-gistfile1-txt-LC38">CDEF:totala=ds0ak,ds1ak,+,ds2ak,+,ds3ak,+,ds4ak,+ </div></pre>
Your CDEF make all UNK value are equal to 0, including
uncollected data (data collect in the future)<br>
Be careful, because if your display range ends after your last
entry. Your UNK (uncollected) values are replace by 0.<br>
So using LAST return 0.<br>
<br>
Try to use ADDNAN (<a moz-do-not-send="true"

instead of "+" and delete this line.<br>
<pre class="line-pre"><div class="line" id="file-gistfile1-txt-LC36">CDEF:ds4ak=ds4a,UN,0,ds4a,IF </div><div class="line" id="file-gistfile1-txt-LC37">CDEF:ds4bk=ds4b,UN,0,ds4b,IF </div></pre>

Hi all,<br>
<br>
I've been using rrdtool quite successfully for some time.
However..... I've now hit a fairly awkward problem, and can't
get my head around it.<br>
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
<a moz-do-not-send="true"
href="https://gist.github.com/cjsoftuk/5024419">https://gist.github.com/cjsoftuk/5024419</a>
is the rrdtool command I'm running (newlines added by me to make
it readable!)<br>
<br>
The problem is, the "Current" column in the legend is always
"0.00 bps".<br>
If I switch from the CDEFs to the DEF, it's fine, but then I'm
missing aggregated data.<br>
<br>
I'm sure I'm being stupid here, however, I can't see where I'm
getting it wrong.<br>
<br>
Could anyone shed some light on the situation?<br>
<br>
Thanks in advance.<br>
<br>
Regards,<br>
<br>
Chris<br>
