Genarate SNMP trap item from alarm list from telnet :: solved :)

[prasad_SL]

This is the way I did...


1. Modified external telnet script to dump the output to a file (log)
2. Read the file and extract lines specific regex and put in to another file; (marked as Newlog)
3. Append the file content by formatting according to SNMP lines


I did it by 6 scripts; including telnet script.
As follows.

1. telnet script

#!/usr/bin/expect

spawn telnet x.x.x.x
send "username"
send "\r"
send "password"
send "\r"
expect "Windows NT Domain:"
send "\r"
expect ">"
send "mml -a"
send "\r"
expect "<"
send "alarmlist command;"
send "\r"
send "exit \r"
send "exit \r"


2. Main command script : : this is the external script places at /usr/lib/zabbix/externalscripts
Alarm dump location is /home/appliance/prasadAXEscripts

#!/bin/bash

/usr/lib/zabbix/externalscripts/isc4A1.sh | tee /home/appliance/prasadAXEscripts/log.txt
sleep 0.25
/home/appliance/prasadAXEscripts/Tony_v1.bash
sleep 0.1

3. Here Tony_v1.bash will trigger 3 new scripts ...

#!/bin/bash

#Extracting A1 and A2 alarms from capture file
/home/appliance/prasadAXEscripts/Mark42AXEAlarmExtractor_v1.sh
sleep 0.1

#Compare New list with Old list and genarate Triggers
/home/appliance/prasadAXEscripts/Mark43AXEFileAnalyser_v1.bash
sleep 0.1

#Tunneling genarated Triggers to Zabbix SNMP train
/home/appliance/prasadAXEscripts/Mark47SnmpTunnel_v1.sh
sleep 0.1


Following are those 3 files...

If you have any better way or issues ...please comment.
