A small rise on the month mysql configuration cards for three days, because on the one hand are not familiar with, on the one hand I was yesterday at 18:00 configuration is completed, there is no data for a long time, they closed the desperate, last night I still entangled or not to continue to study, today opened it, have a data chart. The original mysql monitor, take a little time to take effect.
When you know the right way, I'm on another server configuration, in fact, only 3 minutes
- Mysql association template

Requirements for template operation:
1.Install Zabbix agent and MySQL client.
2.Copy Template_DB_MySQL.conf into folder with Zabbix agent configuration (/etc/zabbix/zabbix_agentd.d/ by default). Don't forget restart zabbix-agent.
3.Create MySQL user for monitoring. For example:
CREATE USER 'zbx_monitor'@'%' IDENTIFIED BY '<password>';
GRANT USAGE,REPLICATION CLIENT,PROCESS,SHOW DATABASES,SHOW VIEW ON . TO 'zbx_monitor'@'%';
For more information read the MYSQL documentation https://dev.mysql.com/doc/refman/8.0/en/grant.html , please.
4.Create .my.cnf in home directory of Zabbix agent for Linux (/var/lib/zabbix by default ) or my.cnf in c:\ for Windows. For example:
[client]
user=zbx_monitor
password=<password>
You can discuss this template or leave feedback on our forum https://www.zabbix.com/forum/zabbix-suggestions-and-feedback/384189-discussion-thread-for-official-zabbix-template-db-mysql
Template tooling version used: 0.35
- Set template mysql end
Note: May not a small rise of the machine and / var / lib / zabbix can not find the template Template_DB_MySQL.conf, so I end up with is another userparameter_mysql.conf
1) mysql monitoring templates to see zabbix in, find / -name userparameter_mysql.conf
[root @ ~] # the Find / -name userparameter_mysql.conf
/backup/soft/zabbix-4.4.6/conf/zabbix_agentd/userparameter_mysql.conf
the first sentence of this document
template_db_mysql.conf of ZABBIX for the Created by # "Template DB MySQL" and of ZABBIX 4.2
2) copied to zabbix_agentd.conf.d / directory
-r /backup/soft/zabbix-4.4.6/conf/zabbix_agentd/userparameter_mysql.conf /usr/local/etc/zabbix_agentd.conf.d/ cp
3) test patterns are valid
zabbix_agentd -t mysql.ping -c /usr/local/etc/zabbix_agentd.conf.d/userparameter_mysql.conf
mysql.ping [T | mysqladmin: Connect to Server AT '-P' failed
error: 'Unknown the MySQL Host Server' -P '(2)'
. 4) to modify the template
cat /usr/local/etc/zabbix_agentd.conf.d/userparameter_mysql.conf
UserParameter = mysql.ping [*], mysqladmin -h "$ 1" -P "$ 2" ping
said -P do not know this parameter $ 1 $ 2 should be passed in from elsewhere parameters.
The following testing process tangled write, write final shape of the template
UserParameter=mysql.ping[], HOME=/etc/zabbix mysqladmin ping
UserParameter=mysql.get_status_variables[],HOME=/etc/zabbix mysql -sNX -e "show global status"
UserParameter=mysql.version[],HOME=/etc/zabbix mysqladmin version
UserParameter=mysql.uptime,HOME=/etc/zabbix mysqladmin status | cut -f2 -d ":" | cut -f1 -d "T" | tr -d " "
UserParameter=mysql.db.discovery[],HOME=/etc/zabbix mysql -sN -e "show databases"
UserParameter=mysql.dbsize[], HOME=/etc/zabbix mysql -sN -e "SELECT SUM(DATA_LENGTH + INDEX_LENGTH) FROM INFORMATION_SCHEMA.TABL
ES WHERE TABLE_SCHEMA='$3'"
UserParameter=mysql.replication.discovery[], HOME=/etc/zabbix mysql -sNX -e "show slave status"
UserParameter = mysql.slave_status [*], HOME = / etc / zabbix mysql -sNX -e "show slave status"
I copied this template and, in fact, only one more HOME = / etc / zabbix (native to believe template wording)
5) and do some of that .my.cnf
[MySQL]
the User = zbx_monitor
password = Javaer123456
[mysqladmin]
the User = zbx_monitor
password = Javaer123456
path /etc/zabbix/.my.cnf and above HOME = / etc / zabbix is not the same, right, HOME that means "Big Brother I came here. "
6) Restart zabbix_agentd
After this step, wait, wait 5 minutes, 10 minutes, do not worry.
7) Look data monitoring> Latest data
8) Look at the monitor icon> Graphics in

I think the process is repeated tangled userparameter_mysql.conf because a lot of things have not figured out.
