[Xymon] Custom 60 second interval test still has 5 min interval graph

Tue Jun 30 23:21:35 CEST 2015

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>

                        <!-- 2015-06-30 17:10:00 EDT / 1435698600 --> <row><v> 4.4100000000e+01 </v></row>
                        <!-- 2015-06-30 17:11:00 EDT / 1435698660 --> <row><v> 4.1500000000e+01 </v></row>
                        <!-- 2015-06-30 17:12:00 EDT / 1435698720 --> <row><v> 2.4500000000e+01 </v></row>
                        <!-- 2015-06-30 17:13:00 EDT / 1435698780 --> <row><v> 1.2000000000e+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!
