本篇blog介绍在 node1、node2 节点上使用 shell脚本 监控 postgresql的具体过程。
使用 shell 脚本监控，就是比较灵活一点。

创建 shell_postgresql96.conf

导入监控模版

zabbix web 页面操作

Configuration -> Templates -> Import

可以看到模版 Template_Shell_PostgreSQL96.xml

需要注意的是模版文件的 value_type 需要和 Shell_postgresql96.conf 对应之类型一致，否则会报错。
value_type integer
0 - 浮点数
1 - 字符
2 - 日志
3 - 数字（无正负）
4 - 文本

主机配置模板

zabbix web 页面操作

Configuration -> Hosts

点击某台机器，进去选择 Templates，
点击Select，选中 Template DB Shell PostgreSQL96 ,点击页下面的 Select
点击 Add
点击 Update

这个 shell 脚本是对 postgresql 监控的补充。
