Can someone explain what is happening in this example? I would like to compute a trend along with my data.<br><br>$ rrdtool create temp.rrd --step 1 DS:temp:GAUGE:30:0:U DS:trend:COMPUTE:temp,10,TRENDNAN RRA:AVERAGE:0.5:1:10<br>
$ rrdtool update temp.rrd N:3<br>ERROR: temp.rrd: malformed trend arguments<br><br>
