Would someone please explain the CF LAST and it's purpose?!! I can't find a discussion of what it should really do.
I think it would be nice if the CF LAST returned values from the last data update but the enclosed script indicates otherwise. The script updates the DS ds1 with the value 10 way back in time but then using the CF LAST actually returns the "now/current" value: logging value 10 at Mon Jan 10 09:56:06 2000 CST (947519766) last update was at Mon Jan 10 09:56:06 2000 CST (947519766) last value logged is 10.00 "last" as per CF LAST is NaN What gives? steve - - - systems & network guy high energy physics university of wisconsin - - - #!/bin/bash rrdtool create -b 947519465 last-confusion-test.rrd \ DS:ds1:GAUGE:1800:0:U \ RRA:AVERAGE:0.5:1:5 rrdtool update last-confusion-test.rrd -t ds1 947519466:10 echo "logging value 10 at Mon Jan 10 09:56:06 2000 CST (947519766)" rrdtool update last-confusion-test.rrd -t ds1 947519766:10 cat <<_EOT_>./last-confusion-test.rrdcgi #!/usr/local/nrg/bin/rrdcgi last update was at <RRD::TIME::LAST last-confusion-test.rrd "%c %Z"> (<RRD::TIME::LAST last-confusion-test.rrd "%s">) <RRD::GRAPH /dev/null --imginfo '' --end <RRD::TIME::LAST last-confusion-test.rrd "%s"> DEF:ds1=last-confusion-test.rrd:ds1:AVERAGE PRINT:ds1:AVERAGE:"%.2lf" > last value logged is <RRD::PRINT 0> <RRD::GRAPH /dev/null --imginfo '' DEF:ds1=last-confusion-test.rrd:ds1:AVERAGE PRINT:ds1:LAST:"%lf" > "last" as per CF LAST is <RRD::PRINT 0> _EOT_ chmod 755 ./last-confusion-test.rrdcgi ./last-confusion-test.rrdcgi < /dev/null | grep last rm -f ./last-confusion-test.rrdcgi -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-developers WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
