Content-Type: text/plain; charset="US-ASCII" Hello List...
I'm a newbie to mrtg/rrd/perl, and am having problems with the realworld example of the rrd tutorial: (http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/tutorial/rrdtutorial.html) ---> According to the doc I created an rrd: rrdtool create /home/mrtg/rras/10_11_42_1.rrd \ DS:input:COUNTER:600:U:U \ DS:output:COUNTER:600:U:U \ RRA:AVERAGE:0.5:1:600 \ RRA:AVERAGE:0.5:6:700 \ RRA:AVERAGE:0.5:24:775 \ RRA:AVERAGE:0.5:288:797 \ RRA:MAX:0.5:1:600 \ RRA:MAX:0.5:6:700 \ RRA:MAX:0.5:24:775 \ RRA:MAX:0.5:288:797 ---> I update the rrd with the following script: #! /usr/bin/perl -w $in = `snmpget -c public 10.11.42.1 1.3.6.1.2.1.2.2.1.10.3`; $out = `snmpget -c public 10.11.42.1 1.3.6.1.2.1.2.2.1.16.3`; $inSpace= (index $in, ": ")+2; $outSpace = (index $out, ": ")+2; $inBytes = substr($in, $inSpace); $outBytes = substr($out, $outSpace); chomp($inBytes); chomp($outBytes); system("/usr/local/rrdtool-1.0.40/bin/rrdtool update /home/mrtg/rras/10_11_42_1.rrd N:$inBytes:$outBytes"); ---> After running for >17hours, I generate the graph with the following (again taken from the docs). ---> The resulting gif is attached. /usr/local/rrdtool-1.0.40/bin/rrdtool graph /var/www/html/mrtg/10_11_42_1.gif --start -86400 DEF:inoctets=/home/mrtg/rras/10_11_42_1.rrd:input:AVERAGE DEF:outoctets=/home/mrtg/rras/10_11_42_1.rrd:output:AVERAGE AREA:inoctets#00FF00:"In traffic" LINE1:outoctets#0000FF:"Out traffic" ---> If I do an "rrdtool dump" to an xml file, there is data in the file, for example: <!-- 2002-12-17 13:30:00 GMT+1 / 1040135400 --> <row><v> 3.2336765017e+06 </v><v> 2.9610353944e+06 </v></row> <!-- 2002-12-17 14:00:00 GMT+1 / 1040137200 --> <row><v> 1.4217670000e+04 </v><v> 9.9994894444e+03 </v></row> <!-- 2002-12-17 14:30:00 GMT+1 / 1040139000 --><row> <v> 1.3060485795e+04 </v><v> 9.0714542913e+03 </v></row> <!-- 2002-12-17 15:00:00 GMT+1 / 1040140800 --> <row><v> 9.5253486489e+03 </v><v> 5.2754329310e+03 </v></row> ---> Furthermore, the command "rrdtool last" gives me a correct time for the last update of the rrd file. ---> My problem is that there is little or no data showing up in the graph. If anyone has any ideas - I'd be grateful for your help. thanks /j-p. -- Attached file removed by Ecartis and put at URL below -- -- Type: image/gif -- Size: 12k (12793 bytes) -- URL : http://www.ee.ethz.ch/~slist/pantomime/10_11_42_1.gif -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
