Log monitoring doesn't work

[gastonace1]

Hello everyone,
I'm working with Zabbix 3.2, and I need to monitor some logs when they have an "error" string on them, but I cannot make it work.
Here's what I'm doing:

First I've made an item in the workstation, called "Log monitor",
Type: Zabbix agent(active),
Key: logrt["C:\zabbix\zabbix_agentd.log"],
Type of Information: Text,
Update interval: 30 sec.

Then I've made a trigger named "log monitor testing", with this values:
severity: info,
Expression: {DT0163658:logrt["C:\zabbix\zabbix_agentd.log"].str("started",120)}=0
(i've made this using the "Add" button, "find string V in last most recent value", and the string is "started" just for testing)

But I cannot make it work. Can someone help me do this? I've read the documentation but seems like I'm missing something.

I solved it.
My configuration file was missing 2 thigs:
1- Hostname in zabbix_agentd.conf must be equal to Zabbix front end (Configuration -> Hosts -> modify the hostname variable in the host)
2- ServerActive= 1.1.1.1 (where 1.1.1.1 is your Zabbix server)

Now my problem is that the Log is always writing, so the alarm appear and disappear too quick so I can't track the problem.
Do anyone know how can I make it to be a only manual close to a trigger alarm in the Dashboard?

Hi,

For close manual a trigger. In trigger configuration, enable the Allow manual close option (In the templates or others).

Thanks
