Difference between PROBLEM and OKAY trigger ( zabbix agent unreachable for 5 minites)

[zabbixfk]

Hi All,


I have configured trigger for hosts to verify zabbix agent is reachable or not using below trigger

{IT-Servers-Windows:agent.ping.nodata(300)}=1

Whenever above trigger is triggered, i have configured corresponding actions in Configurations -> Actions to send email. So i get 2 emails.
One for problems with subject as PROBLEMlike this

Trigger: Zabbix agent on HOSTNAME - 192.168.1.123 is unreachable for 5 minutes
Trigger status: PROBLEM
Trigger severity: Average
Trigger URL:

Item values:

1. Zabbix Agent Ping (HOSTNAME - 192.168.1.123:agent.ping): 1

After some time i get another email with OK as subject with below contents

Trigger: Zabbix agent on HOSTNAME - 191.168.1.123 is unreachable for 5 minutes
Trigger status: OK
Trigger severity: Average
Trigger URL:

Item values:

1. Zabbix Agent Ping (HOSTNAME - 192.168.1.123:agent.ping): 1

The point i don't understand is, i get both OK as well as PROBLEM with same contents, should't it send with different body, i mean this should trigger when

agent.ping

is zero.

Please point out what i am doing wrong. Any pointers are greatly helpful.

Thanks
