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:

                    <!-- 2015-06-30 16:53:00 EDT / 1435697580 --> <row><v> 1.0033333333e+01 </v></row>

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!
