Problem with add log monitor

[a_minor_bush]

Hi everyone,
i'm new user Zabbix and i have problem with add log monitor tomcat's application:

1. Step: Add Items
- Zabbix agent (active)
- key: log[/home/application/logs/catalina.out,ERROR]
- update interval: 30s
- history storage period: 90d

2. Step: Add triggers
- {server:log[/home/application/logs/catalina.out,ERROR].regexp("ERROR")}>0

3. Step: Test
- echo "ERROR" >> /home/application/logs/catalina.out


...and my dashboard is empty. What did I forget about?


best regards

Please check the screen of latest data.
Have you acquired log contents with the created item?

hmmm...

in Latest data section I dont see that item.

Please display the item list of the host and check whether there is a red mark on the right side of the log item.
If the red mark is displayed, please move the mouse pointer to that red mark and check the message.

Is not the Zabbix agent authorized to access files?
Please check not only the file but also the permissions of the directory, so that the Zabbix agent can access it.

Details should also be output to the log file.
