I've followed the thread on exec examples, but I'm still having some
trouble of my own. I have the following lines in my snmpd.conf file:
extend .1.3.6.1.4.1.7594.400 swap_percent
/etc/snmp/bin/check_swap_pct.bash
monitor -r 10 -u citadelInternal -o .1.3.6.1.4.1.7594.400.101
"cig-swap_percent" .1.3.6.1.4.1.7594.400.100 = 0
The script check_swap_pct.bash is a simple bash script which returns a
number which equals percent swap used as a whole number, and also
returns this same number as its exit status.something like:
#!/bin/bash
PCT=`/usr/bin/free -t | awk '$1 ~ /Swap:/ {print $3/$2 * 100 }' - | awk
-F. '{print $1}'`
echo $PCT
exit $PCT
When I run an snmpwalk I get the following data, which I am having
trouble understanding.and the monitor line from the snmpd.conf file is
not working as I would like/expect:
[EMAIL PROTECTED] snmp# snmpwalk -v 2c -c public localhost

I hope this provides all the detail necessary to help a beginner get
some of the extensible functionality for custom scripts going. =)
Thanks in advance.
