Zabbix3.4用自帶模板監控mysql

MySql

zabbix_agent客戶端操作

  1. 建立mysql使用者，使用zabbix賬號連線本地mysql

mysql> GRANT ALL ON . TO 'zabbix'@'localhost' IDENTIFIED BY '123456';
mysql> FLUSH PRIVILEGES;

  1. 在zabbix_agentd服務目錄下建立.my.cnf
    我的zabbix_agentd在/etc/zabbix/sbin/zabbix_agentd，所以我在/etc/zabbix下建立.my.cnf
    cd /etc/zabbix
    cat ./my.cnf

[client]
user=zabbix
password=123456

  1. 修改userparameter_mysql.conf檔案
    mv ./conf/zabbix_agentd/userparameter_mysql.conf_default ./conf/zabbix_agentd/userparameter_mysql.conf
    vim ./conf/zabbix_agentd/userparameter_mysql.conf
# 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=/etc/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>,<table>,<type>].
# 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=/etc/zabbix mysql -N'

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

將HOME=/var/lib/zabbix改成剛才放.my.cnf的目錄，我這裡是/etc/zabbix

  1. 修改zabbix_agentd.conf配置檔案
    新增Include選項

Include=/etc/zabbix/conf/zabbix_agentd/*.conf

  1. 重新啟動zabbix_agentd

pkill -9 zabbix_agentd
/etc/zabbix/sbin/zabbix_agentd -c /etc/zabbix/conf/zabbix_agentd.conf

在Zabbix Server端操作

用zabbix_get命令進行測試
zabbix_get -s host-name-or-IP [-p port-number] [-I IP-address] -k item-key

zabbix_get -s 192.168.0.5 -p 10050 -k "mysql.status[Uptime]"
103723

可以獲取資料，配置成功

  1. 在zabbix的web介面給主機新增Template DB MySQL模板，操作略
