the mysql commands are working fine:

mysqladmin --defaults-file=/etc/zabbix/scripts/config.cnf --socket=/var/lib/mysql/mysql.sock ping
mysqld is alive
mysql --defaults-file=/etc/zabbix/scripts/config.cnf --socket=/var/lib/mysql/mysql.sock -e "Show slave status\G"|/bin/grep -w 'Slave_IO_Running'
Slave_IO_Running: Yes

now, everything is working on that server, except this mysql part, also this configuration is working very well on other servers, with the same zabbix server and same version of zabbix agentd

any ideea what can be the problem, and how to solve it ?

You don't say what version of the zabbix-agent is in use on the client. If I remember correctly, the default path to the Include directory changed at some point.

You're not specifying "Include=" in the zabbix_agentd.conf on the client that is failing. Are you specifying it on the clients that are working? Are those clients using the same directory?

wow, thank you, that was it, now I'm sorry that I didn't think about that myself
