Hi all, I'm experiencing with RRDTools to generate graphs of KPI of some platforms. Simplest KPI to plot are referred to webservices. With a simple shell script run by cron every 5 minutes I log on a file these data:
23/01 14:25 0.014 OK 1138022700 23/01 14:30 0.013 OK 1138023000 23/01 14:35 0.014 OK 1138023300 23/01 14:40 0.018 OK 1138023600 23/01 14:45 0.014 OK 1138023900 Then I put third and last field to my rrd database: rrdtool update mydatabase.rrd $TIMESTAMP:$TIMEVALUE So my idea was to plot a graph with every measure and the math formula for polynomial tendency. Scale is from 0.000 and 10.000 . When a webserver does not respond value shown is 0.000 . By default I've created db as shown in the example, but value of average is not interesting for me: rrdtool create mydatabase.rrd --start 1138017600 DS:responsetime:COUNTER:600:U:U RRA:AVERAGE:0.5:1:24 RRA:AVERAGE:0.5:6:10 It's possbile to graph only DS data? Any tips for me?
