Shell Script - Generate SNMP Traps

Good morning to you all

Iīm kinda of a noob to scripting, and my knowledge is still very basic: anyway, Iīve developed a small .sh script with the following purpose:

- it will check a result file, checking if it has any values, or if itīs empty
- if itīs empty it will send an email

What i wanted to do, is eliminate the email part and generate some kind of snmp trap to be used for Nagios for instance, and create an alarm.

Does anybody know how to do that? Any help is apreciated. Thkx

Here goes the code:


##############################################

cat /var/www/monitor/scripts/TestProbes/probelist.txt | while read probe

do


if [[ -s /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt ]] ; then

echo "Probe has data at $(date +%Y-%m-%d) $(date +%H:%M:%S)" > /var/www/monitor/scripts/TestProbes/results.txt

else


SUBJECT="No\\ Service\\ at\\ "$probe" "
EMAIL="XXXX@XXXX.com"
EMAILMESSAGE="mail"
echo "====================================================
A "$probe" ISNīT WORKING:"> $EMAILMESSAGE
echo "$(date -d "-3 hours" +%Y-%m-%d) $(date -d "-1 hours" +%H:%M:%S)
====================================================" >>$EMAILMESSAGE

su -c "/usr/bin/mail -s $SUBJECT $EMAIL < $EMAILMESSAGE" Probe_Tester


fi

rm /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt
touch /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt
chmod 777 /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt


done

openipmish(1)						 Shell interface to an IPMI system					     openipmish(1)

NAME
openipmish - Shell interface to an IPMI system SYNOPSIS
openipmish [option] DESCRIPTION
The openipmish is a command interpreter that gives the full power of the OpenIPMI library to a user-level command language. It is designed so it can easily be driven with a scripting language like TCL, it has well-formed output. openipmish starts up with no connections or anything of that nature. You must enter commands to make connections to domains. OPTIONS
--dmsg Turn on message debugging, this will dump all messages to debug log output. --drawmsg Turn on raw message debugging, this will dump all low-level messages to debug log output. This differs from normal message debug- ging in that all protocol messages are also dumped, not just IPMI messages. --dmem Turn on memory debugging, this will cause memory allocation and deallocations to be checked. When the program terminates, it will dump all memory that was not properly freed (leaked). --dmsgerr Turn on printing out low-level message errors. --dlock Turn on lock debugging, this will check lock operations to make sure that locks are help in all the proper places and make sure that locks are properly nested. -x <string>, --execute <string> Execute the given string at startup. This may be entered multiple times for multiple commands. --glib Use glib for the OS handler. --snmp Enable the SNMP trap handler. openipmish must be compiled with SNMP code enabled for this option to be available. --help Help output COMMANDS
openipmish follows the standard command syntax defined in ipmi_cmdlang(7). See that for the details on most commands. The IPMI manual that comes with OpenIPMI will also be quite handy. openipmish defines some commands that are not in the standard command language. These are: read Read and execute commands from the given file. exit Quit redisp_cmd on|off Normally, openipmish redisplays the command line when an event comes in. This is nice for interactive use, but bad for scripting. This lets you turn that function on and off. SEE ALSO
