CentOS环境下Zabbix监控PostgreSQL
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
1. 安装libzbxpgsql
根据官方文档进行安装即可。
http://cavaliercoder.com/libzbxpgsql/documentation/module-installation/
rpm -ivh https://download.postgresql.org/pub/repos/yum/9.5/RedHat/rhel-6-x86_64/pgdg-centos95-9.5-3.noarch.rpm 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
[root@im109 packages]# find / -name libzbxpgsql.so [root@im109 packages]# rpm -ivh --force libzbxpgsql-1.1.0-1.el6.x86_64.rpm error: Failed dependencies: libconfig.so.8()(64bit) is needed by libzbxpgsql-1.1.0-1.x86_64 zabbix-agent >= 3.0.0 is needed by libzbxpgsql-1.1.0-1.x86_64 [root@im109 packages]# rpm -ivh --force libzbxpgsql-1.1.0-1.el6.x86_64.rpm --nodeps Preparing... ########################################### [100%] 1:libzbxpgsql ########################################### [100%] [root@im109 packages]# find / -name libzbxpgsql.so /usr/lib64/zabbix/modules/libzbxpgsql.so [root@im109 packages]# ln -s /usr/lib64/zabbix/modules/libzbxpgsql.so /usr/local/zabbix/lib/
2. 配置zabbix配置文件zabbix_agentd.conf
[root@im109 log]# /usr/local/zabbix/sbin/zabbix_agentd -t pg.modver zabbix_agentd [21910]: starting agent module libzbxpgsql 1.1.0 zabbix_agentd [21910]: using module configuration file: /etc/zabbix/libzbxpgsql.conf pg.modver [s|libzbxpgsql 1.1.0, compiled for Zabbix 3.2.3] [root@im109 log]# /etc/init.d/zabbix-agentd restart Shutting down Zabbix agent: [ OK ] Starting Zabbix agent: [ OK ]
3. 创建监控用户
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 Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+----------+----------+-------------+-------------+----------------------- postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres wiseucmsg | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =Tc/postgres + | | | | | postgres=CTc/postgres+ | | | | | monitoring=c/postgres (4 rows) wiseucmsg=>
4. 导入监控模板
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。
