# 4. Set <strong>the</strong> mailtarget (who is getting <strong>the</strong> report).<br />

#<br />

# 6. Define <strong>the</strong> message size. The following is a list of suggested<br />

# sizes:<br />

# 56-bits<br />

# 256-bits<br />

# 512-bits<br />

# 768-bits<br />

# 1000-bits<br />

# 1500-bits<br />

# Keep in mind <strong>the</strong> number of ICMP messages and <strong>the</strong>ir size affect<br />

# <strong>the</strong> runtime of <strong>the</strong> script and <strong>the</strong> expected round-trip results. Larger<br />

# packets will take longer <strong>to</strong> process. Larger packet sizes (above 512)<br />

# also may overrun <strong>the</strong> application buffer. So when configuring <strong>the</strong><br />

# script for sending large packet sizes, keep <strong>the</strong> number of requests<br />

# low.<br />

#<br />

# This is set in <strong>the</strong> Check Script command section of <strong>the</strong> script.<br />

#<br />

# To enable <strong>the</strong> fast packet option if desired, by adding <strong>the</strong> -f<br />

# flag <strong>to</strong> <strong>the</strong> command line.<br />

#<br />

# For best results run <strong>the</strong> script at different points during normal<br />

# usage hours. Keep track of <strong>the</strong> data <strong>to</strong> establish a performance<br />

# baseline<br />

.<br />

# Large shifts in performance should be investigated.<br />

#<br />

# Ping Variables<br />

# Set <strong>the</strong> Target<br />

target=<br />

# Set <strong>the</strong> ICMP message count, 20 is <strong>the</strong> default.<br />

pc=20<br />

# Set <strong>the</strong> UNIX binary paths<br />

ping=/bin/ping<br />

mail=/usr/bin/Mail<br />

rm=/bin/rm<br />

tail=/usr/bin/tail<br />

cat=/bin/cat<br />

# Set <strong>the</strong> temp path<br />

temp=/tmp<br />

# Set <strong>the</strong> mail target<br />

mailtarget=anyuser@any.com
