This program is meant to be exexcuted on a NetScout probe. It requires access to "/opt/NetScout/rtm/tools/printstats -h" and parses the output from that program. The following text is an example of printstats -h output:

---------------------------- Interface 3 ----------------------------
First packet time: 1507661100:0
Last packet time: 1508068066:835502020

When you execute nsifstat.pl the output should look something like this:

./nsifstat.pl

telegraf example conifg:

After you have nsifstat.pl working, use the following telegraf.conf input config to instruct telegraf to call nsifstat.pl.

[[inputs.exec]]
  commands = ["/opt/telegraf/bin/scripts/nsifstat.pl"]
  timeout = "5s"
  data_format = "graphite"

debug output:

If you are having trouble making this work, try setting $debug = 1; in the script to see where things are failing.
