[Supriya123]

  Hi All,
  I am new to zabbix and I am trying to monitor a pattern in /var/log/messages. If it found the message, trigger an alert or else don't trigger an alert
  
  Here is my item
  Type: Zabbix Agent(Active)
  Key:log[/var/log/messages,/home/appl/bin/test_all.pl]
• Type of information: log
  
  Here is my tigger:
  {xxx-supd-xxx.xxx.net:log[/var/log/messages,/home/appl/bin/test_all.pl].logsource(/var/log/messages)}=1
  
  And I can see content in my messages
  [root@vlib-supd-010101-1 ~]# cat /var/log/messages | grep -i "/home/appl/bin/test_all.pl"
