I am monitoring the Packets per Second on a router port and I want to
send an email when the rate goes over 80,000.  You can see my config

Target[testpps]: at 128.2

Options[testpps]: growright, gauge, nopercent

MaxBytes[testpps]: 200000

Unscaled[testpps]: dwmy

ShortLegend[testpps]: pps

Legend1[testpps]: I1 packets per second

Title[testpps]: I1 packets per second

PageTop[testpps]: <H1>I1 packets per second </H1>

ThreshMaxI[testpps]: 80000

ThreshProgI[testpps]: /var/www/perl/tcr1-57-pps.sh




Here is what I get when I get the numbers with snmpget:


snmpget -v2c -c public .

SNMPv2-SMI::enterprises.2636. = Gauge32: 25487


You can see it returns 25,487 which seems valid and it appears in my rrd


When I run MRTG against the config, here is what I get:


/usr/bin/mrtg /usr/local/cfg/testpps.cfg 

WARNING: can't do threshold checking for target testpps(i) -- No valid
current data


Does anyone have any idea why the threshold checking is failing?
