Zabbix 监控Mysql Slave

  1. userparameter_mysql_slave_status.conf 放置到 /etc/zabbix/zabbix_agent.d/下。

详细配置内容:

# 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.slave.status[*], echo ‘show slave status\G;’ | mysql | awk ‘$$1 ~ /$1/ {print $$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

2. 修改上述配置文件中 UserParameter=mysql.slave.status[*], echo ‘show slave status\G;’ | mysql | awk ‘$$1 ~ /$1/ {print $$2}’

具体来说,如果.my.cnf在 /etc/zabbix下。那么改为:

UserParameter=mysql.slave.status[*], echo ‘show slave status\G;’ |HOME=/etc/zabbix mysql | awk ‘$$1 ~ /$1/ {print $$2}’
