Hi,

it’s been more than 3 weeks that Centreon HA Slave node’s RAM is HIGH and increasing, before we allocated 8GB RAM, we keep adding more RAM but the issue doesn”t get solved!!

now allocated RAM is 16 GB.

i tried restarting the Slave node, but still the same issue.

replication is fine, cluster is fine, so i’m not sure what’s causing this high utilisation!!!

centreon version: Centreon 23.04.9

 

 

 

 

can anyone help here?

Hi @adilbouazzaoui can you try to check thread_cache_size and max_connections parameters

for max_connections parameters, i’m not sure where to find it!!

You can use:

SHOW GLOBAL VARIABLES LIKE 'max_connections';

or

SELECT @@global.max_connections;

 

 

Can you do the same with thread_cache_size ?

Do you have the same version of MariaDB between master and slave server?

May be you can hve a look to https://www.nexcess.net/help/mariadb-performance-tuning/

 

yes same MariaDB version.

for this: https://www.nexcess.net/help/mariadb-performance-tuning/ 

it’s complicated, and i think i may mess with the configuration.
