Zabbix监控PostgreSQL
1. 安装libzbxpgsql
2. 配置zabbix配置文件zabbix_agentd.conf
3. 创建监控用户
4. 导入监控模板
5. 主机链接模板,设置宏变量
因上次用到了PostgreSQL,而所使用的监控又是Zabbix,所以找到了此插件用于Zabbix监控PostgreSQL。
插件网站:PostgreSQL monitoring for Zabbix
Github地址:https://github.com/cavaliercoder/libzbxpgsql
环境:
CentOS6.8
Zabbix3.2.1
PostgreSQL9.5.6

yum -y install postgresql95-libs # 已经安装可忽略
yum -y install libconfig
wget http://cdn.cavaliercoder.com/libzbxpgsql/yum/zabbix32/rhel/6/x86_64/libzbxpgsql-1.1.0-1.el6.x86_64.rpm

创建一个用户,开放你所要监控的数据库只读权限给它,为了安全,把权限做到最小化。
我用的pgpool-II。
psql -h 10.1.0.115 -U postgres -p9999
Password for user postgres:
psql (9.5.6)
Type "help" for help.
postgres=# CREATE ROLE monitoring WITH LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE;
CREATE ROLE
postgres=# GRANT CONNECT ON DATABASE wiseucmsg TO monitoring;
GRANT
postgres=# alter user monitoring with password 'password';
ALTER ROLE
使用创建的用户能登录查看相应数据库,则可进行下一步。
[root@im109 pgpool-II]# psql -h localhost -U monitoring -p 54321 wiseucmsg
psql (9.5.6)
Type "help" for help.
wiseucmsg=> \l
List of databases

wiseucmsg=>
模板在Github上有:
https://github.com/cavaliercoder/libzbxpgsql/tree/master/templates
5. 主机链接模板,设置宏变量
{$PG_CONN} => host=localhost port=54321 user=monitoring connect_timeout=10
{$PG_DB} => wiseucmsg
有图形出现,则监控成功。
