Hi Jeremy,
I’m viewing the graph on the custom test page. The data is being reported in via data message if that makes a difference. Not sure what you mean by reducing the trends period?

I /think/ the RRD side of things is correct, so it must be the graphing that's the problem.
Where are you viewing the graph? On the "stats" page? If so, have you tried reducing the trends period to (say) 30 minutes?

Hi JC,
Maybe I missed it when it's staring me in the face, but I still don't understand why it's not showing the 1 minute resolution when it is saving it into the RRD. The resulting RRD from the configuration I posted has a 60 second step, a 180 second heartbeat, and the data is being stored every 60 seconds, all of that verified by rrdtool dump. So I have successfully increased the resolution of the RRD; but even though it's stored every minute the resulting graph only registers changes in values every 5 minutes.

This is correct.
The data format for a "round robin database" is fixed at creation time for
a certain number of data points at a certain interval, using a certain
method for combining them (typically 'AVERAGE' by default).
When you're increasing the number of data points you're submitting, you're
putting more data in, but you're still only going to see 5 minute average
"chunks" (and the larger ones). To actually increase the resolution you're
saving at, you'll want to use (I believe) the 'rrdtune' command.
Alternatively, some find it easier to export/re-import the data into a new
file.
HTH,

Hey everyone,
I created a custom test and RRD definition because I wanted to reduce the
interval time on a few graphs from 5 minute resolution to 1 minute. I got
the data to be logged once every minute, which I verified is hitting the
RRD. The problem is that when I view the graph it's still got a
resolution of 5 minutes.
Here's the partial RRDTool dump:

So the data is getting logged every 60 seconds. It's also rolling up to
the 5 second, etc, values.
Here's the line from xymonserver.cfg:
SPLITNCV_cpustat="*:GAUGE:180:0:100" #Configure for 60 second
intervals,
range of 0-100
Here's the lines from rrddefinitions.cfg:
[cpustat]
-s 60
RRA:AVERAGE:0.1:1:120
RRA:AVERAGE:0.5:5:576
RRA:AVERAGE:0.5:30:576
RRA:AVERAGE:0.5:120:576
RRA:AVERAGE:0.5:1440:576
RRA:MAX:0.1:1:120
RRA:MAX:0.5:5:576
RRA:MAX:0.5:30:576
RRA:MAX:0.5:120:576
RRA:MAX:0.5:1440:576
Here's the graph definition:
[cpustat]
FNPATTERN ^cpustat.(.+).rrd
TITLE % CPU usage
YAXIS Percent
DEF:p at RRDIDX@=@RRDFN@:lambda:MAX
LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@
GPRINT:p at RRDIDX@:LAST: \: %5.0lf (cur)
GPRINT:p at RRDIDX@:MAX: \: %5.0lf (max)
GPRINT:p at RRDIDX@:MIN: \: %5.0lf (min)
GPRINT:p at RRDIDX@:AVERAGE: \: %5.0lf (avg)\n
I had read that RRDTool should use the lowest resolution available, which
is 1 minute for this RRD. So why are the graphs not going less than 5
minute intervals when zooming in? Any ideas?
Thanks!
