Zabbix監控PostgreSQL

Zabbix監控PostgreSQL 安裝libzbxpgsql 配置zabbix配置文件zabbix_agentdconf 創建監控用戶 導入監控模板 主機鏈接模板設置宏變量
因上次用到了PostgreSQL,而所使用的監控又是Zabbix,所以找到了此插件用于Zabbix監控PostgreSQL。
插件網站:PostgreSQL monitoring for Zabbix
Github地址:https://github.com/cavaliercoder/libzbxpgsql
環境:
CentOS6.8
Zabbix3.2.1
PostgreSQL9.5.6
1. 安裝libzbxpgsql
根據官方文檔進行安裝即可。
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.rpmyum -y install postgresql95-libs # 已經安裝可忽略yum -y install libconfigwget 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 --nodepsPreparing... ########################################### [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
1
[root@im109 log]# /usr/local/zabbix/sbin/zabbix_agentd -t pg.modverzabbix_agentd [21910]: starting agent module libzbxpgsql 1.1.0zabbix_agentd [21910]: using module configuration file: /etc/zabbix/libzbxpgsql.confpg.modver [s|libzbxpgsql 1.1.0, compiled for Zabbix 3.2.3][root@im109 log]# /etc/init.d/zabbix-agentd restartShutting down Zabbix agent: [ OK ]Starting Zabbix agent: [ OK ]
3. 創建監控用戶
創建一個用戶,開放你所要監控的數據庫只讀權限給它,為了安全,把權限做到最小化。
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 ROLEpostgres=# GRANT CONNECT ON DATABASE wiseucmsg TO monitoring; GRANTpostgres=# alter user monitoring with password 'password';ALTER ROLE
使用創建的用戶能登錄查看相應數據庫,則可進行下一步。
[root@im109 pgpool-II]# psql -h localhost -U monitoring -p 54321 wiseucmsgpsql (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. 導入監控模板
模板在Github上有:
https://github.com/cavaliercoder/libzbxpgsql/tree/master/templates
5. 主機鏈接模板,設置宏變量
{$PG_CONN} => host=localhost port=54321 user=monitoring connect_timeout=10
{$PG_DB} => wiseucmsg
