Hi Guys,

Need help.

Hi @jnewtocentreon which version of Centreon did you installed?

Can you see error in /var/log/php-fpm/centreon-error.log when you access to this page?

Regards,

Hi @Laurent,
The above issue is fixed, but there is now a new issue.
When I add any new hosts, they don’t show up in Centreon dashboard, they only show up when I restart my centreon server.

Could you please help me with this?

When you configure resources, you need to deploy configuration: https://docs.centreon.com/docs/monitoring/monitoring-servers/deploying-a-configuration/

@Laurent 
Yes, I even deploy configuration, but still it is not showing.
It only shows if I restart the centreon server

when you export your configuration, do you have errors in /var/log/centreon-gorgone/gorgoned.log?

Hi, there is a lot of error with access to the DBMS.

Can you check your parameters in /etc/centreon/config.d/10-database.yaml?

Badge +2
cat /etc/centreon/config.d/10-database.yaml
database:
  db_configuration:
    dsn: "mysql:host=localhost:port=3306;dbname=centreon"
    username: "centreon"
    password: "XXXXXXXX"
  db_realtime:
    dsn: "mysql:host=localhost:port=3306;dbname=centreon_storage"
    username: "centreon"
    password: "XXXXXXXX"

Hello,

For this issue :

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

could you try to put 127.0.0.1 instead of localhost in you configuration file ?

@jnewtocentreon did you find the solution? I also have the same error on my centreon. 

2024-05-12 22:30:00 - ERROR - MySQL server has gone away
2024-05-12 22:30:01 - ERROR - MySQL server has gone away

 

checked status of centreon db, able to connect, mysql check all ok. 

 

seems like a timeout error after i changed the root password of my machine which hosts centreon. not sure where to update it.
