<div dir="ltr">Thanks for the replies. Adam's reply regarding the way RRD handles the data makes sense. Once I move the test to run every 5 minutes, it did begin to populate the graph. I let it run for hours with the 15 minute run without success (looks like RRD stops caring after 10 minutes). I'll look more into RRD to see if there is some easy way to have this work since it's a valid need to have tests that run less often but you still want to graph for trending purposes. Likely just a user education issue. <div><br><div>I looked at the data message but the man page seemed to indicate that this would only populate a graph only for the trends page. I may revisit it since when I stopped trying to use it, I was still running at 15 minute intervals.</div><div><br></div><div>per WJM's comment, It's a GUAGE, actually. I may look at the devmon option. I may not have been clear on the request to have the data be restricted somehow for the status. It's too easy to have NCV trigger since '=' and ':' are fairly common separators when one provides output. I love the flexibility of NCV but that little foible is a bit annoying. Also note, even when I defined NONE, it still creates an rrd file (I used SPLITNCV). It would also be difficult to set that up for a string that looks like this:</div><div><br></div><div><div>Thu Apr 16 22:33:41 EDT 2015</div></div><div><br></div><div>and creates a rrd file named</div><div>test,Thu_Apr_16_22.rrd</div><div><br></div><div>that is going to create a new rrd file every hour.</div><div><br></div><div>Having to filter the content to change it to use the html entities is (IMHO) a hack that shouldn't be needed. The devmon test apparently already requires this so it really doesn't seem too unreasonable for NCV to handle it the same way.<br></div><div><br></div><div>Just throwing it out there...it's graphing along and I'm happy I was able to figure it out.</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Apr 16, 2015 at 2:58 AM, W.J.M.

<div>long story short. I finally got he graph to show up on my
test page...but the rrd file doesn't seem to be populating the
fields as expected when I run "rrdtool dump". The only thing
I can figure is that the test I'm performing doesn't run every
5 minutes but every 15 minutes. Does that matter? I would
have expected in the worst case that only every 3rd row would
have a value.</div>

Is the DS type DERIVE or COUNTER? In that case two successive
samples, which are 5 minutes apart, are needed to create one data
point in the graph.<span class=""><br>

<div>As a side note, it would be extremely helpful if the NCV
component didn't look at the entire status but required a
comment block (for example) to contain it. That way you could
keep your data stream isolated from your message. For
example:</div>
<div><br>
</div>
<div><!-- NCV data</div>
<div>metric1: 123</div>
<div>metric2: 456</div>
<div>etc</div>
<div>--></div>

Perhaps you can use the devmon format, which encapsulates the data
to trend in an HTML comment section. In that case, one would have to
specify "test=devmon" in stead of "test=ncv" in variable TEST2RRD.
There is no need for an NCV_Something variable, as the DS definition
is included with the data to trend.<span class=""><br>

<div>My test kept creating an rrd file for a date string that

There are (at least) two ways to circumvent that problem:<br>
A) Add "*:NONE" to the NCV_Something variable;<br>
B) Replace all occurrences of ":" and "=" outside the NCV part by
their HTML equivalent, thus ":" and "=".<br>
