I have configured Zabbix to monitor my java application log for string "None of the configured nodes are available".

Everything is working fine, Zabbix will send me alerts when there is a new String "None of the configured nodes are available" entry in the log file, But issue is for each entry of string zabbix trigger alert and I received mail with different-2 event id.

My configuration of the log monitoring is below. I am using the latest version of zabbix server(3.4)

Item configuration:

Description: log monitoring. Key: log[/home/ubuntu/logs/dev.log,None of the configured nodes are available] Type: Zabbix Agent (Active) Type of information: Log Interval :30

Trigger configuration:

Description: Log-None of the configured nodes are available {HOST.NAME}. Expression: {Dev:log[/home/ubuntu/logs/dev.log,None of the configured nodes are available].str(NoNodeAvailableException: None of the configured nodes are available)}=1 PROBLEM event generation mode:Multiple

What I want —

I want for multiple entry in log we received only single alert and problem will resolved manually by us .
