Monitor mysql Service In My Zabbix Server

Now I have to show how to check my zabbix mysql service. Another tutorial how to monitoring mysql service via zabbix. Zabbix is  very important tools for database monitoring system. So I will configure step by step zabbix own server mysql monitor.

★ Install Zabbix server on ubuntu 16.04

★ How To Add Windows Host In Zabbix Server

Step #01: Open zabbix agent configure  /etc/zabbix/zabbix_agentd.conf  file.

root@zabbix-server:~# vim /etc/zabbix/zabbix_agentd.conf

Check user parameter file name as like below.

Step #02: Add zabbix user parameter for mysql server monitoring. Create userparameter_mysql.conf file into /etc/zabbix/zabbix_agent.d/ location. Open vim /etc/zabbix/zabbix_agent.d/userparameter_mysql.conf. Then insert below all lines.

# For all the following commands HOME should be set to the directory that has .my.cnf file with password information.

# Flexible parameter to grab global variables. On the frontend side, use keys like mysql.status[Com_insert].
# Key syntax is mysql.status[variable].
UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'

# Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].
# Key syntax is mysql.size[, ,].
# Database may be a database name or "all". Default is "all".
# Table may be a table name or "all". Default is "all".
# Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".
# Database is mandatory if a table is specified. Type may be specified always.
# Returns value in bytes.
# 'sum' on data_length or index_length alone needed when we are getting this information for whole database instead of a single table
UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'

UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive
UserParameter=mysql.version,mysql -V

Step #03: Type mysql -uroot -ppassw0rd for create database, drop database, create user, create table, drop user, drop table etc.

root@zabbix-server:~#  mysql -uroot -ppassw0rd

See as like below.

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 21406

mysql>

Now create user for send data from mysql databases server with password.

mysql> create user ‘zabbix_user’@’localhost’ identified by ‘passw0rd’;

mysql> grant all privileges on *.* to ‘zabbix_user’@’localhost’;

mysql> flush privileges;

mysql> exit;
Step #04: Check userparameter_mysql.conf file  on /var/lib/zabbix is blank. Now created .my.cnf file on the /var/lib/zabbix/ location.

Open .my.cnf  file as below command.

root@zabbix-server:~#  vim /var/lib/zabbix/.my.cnf

Then insert previously created mysql user and password on .my.cnf file.

[mysql]
user=zabbix_user
password=passw0rd
host=localhost

[mysqladmin]
user=zabbix_user
password=passw0rd
host=localhost

Then zabbix agent restart and mysql service restart.

root@zabbix-server:~#  service zabbix-agent restart

root@zabbix-server:~#  service mysql restart

Step #05: Now goto your zabbix server and check latest data see all data as like below image.

Click Monitoring/Latest data then select Hosts “zabix server name” again click apply.

Thank You Very much.
