Eric, Thanks for the help.
Sorry about the subject. Why does the script need to return 2 values? Can I not plot the same value twice i.e. name the script for both in and out? The OID does return two values, from CISCO-RTTMON-MIB. The two values are because it stores values for two hours, hence two values: [root]# snmpwalk 192.168.10.1 secret .1.3.6.1.4.1.9.9.42.1.3.5.1.2 enterprises.9.9.42.1.3.5.1.2.2.17756118 = 60 enterprises.9.9.42.1.3.5.1.2.2.18116118 = 35 I simply wanted to grab the latest value i.e. for the past 1 hour, 35 in this case. I hoped to plot that initially, and then plot an average for the second line, same graph. Am I missing something?

Also, your external script needs adjustment. First, the script needs to output a minimum of 2 numbers. Second, you only need to call the script once on the target line, with no secret or address. Target[UDPJITTER-RTTLATEST]:`/usr/local/mrtg-2.13.1/bin/RTTSumIn` See http://oss.oetiker.ch/mrtg/doc/mrtg-reference.en.html and search for "External Monitoring Scripts". And just a side note. I install my MRTG just as you did in /usr/local however I create a symbolic link to it at /usr/local/mrtg and run everything using that path. That way when there is a new version of MRTG all I need to do is install it to its own directory and then change the link.
