Icngaweb2 history section not working

Hello.
I am using Ubuntu 18.04, Icinga2 2.11, icingaweb2 2.8, php 7.4. But when I click on history section, nothing shows.
Could you help me on this case.


Thank you much.

Does the history of a single host/service work?

How do the log files look?
/var/log/icingaweb2/icingaweb2.log
/var/log/apache2/error.log
http://yourmonitoringhost/icingaweb2/list/applicationlog

Hi.

Yep, It works

How do the log files look?
/var/log/icingaweb2/icingaweb2.log
/var/log/apache2/error.log
http://yourmonitoringhost/icingaweb2/list/applicationlog

It is normal. These logs show information about when I connect backend DB.

Which database are you using?

If it’s MySQL, you may enable the slow query log and check if there are queries appearing that start with the following:

SELECT eh.id, eh.host_name, eh.host_display_name, eh.service_description,
eh.service_display_name, eh.object_type, eh.timestamp, eh.state, eh.output,
eh.type FROM (SELECT

Please confirm this if that’s the case. (And be sure to include the database version as well)

Hello.
I am using 10.3.13-MariaDB MariaDB Server.

I think it is due to slow query. I have 3000 hosts and 12000 services. I try with another setup with 100 hosts and 400 services then I can see data from history session. Any recommends on this case? Thank you much.
