Zabbix監(jiān)控PostgreSQL
1. 安裝libzbxpgsql
2. 配置zabbix配置文件zabbix_agentd.conf
3. 創(chuàng)建監(jiān)控用戶
4. 導(dǎo)入監(jiān)控模板
5. 主機(jī)鏈接模板,設(shè)置宏變量
因上次用到了PostgreSQL,而所使用的監(jiān)控又是Zabbix,所以找到了此插件用于Zabbix監(jiān)控PostgreSQL。
插件網(wǎng)站:PostgreSQL monitoring for Zabbix
Github地址:https://github.com/cavaliercoder/libzbxpgsql
環(huán)境:
CentOS6.8
Zabbix3.2.1
PostgreSQL9.5.6
1. 安裝libzbxpgsql
根據(jù)官方文檔進(jìn)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.rpm
yum -y install postgresql95-libs # 已經(jīng)安裝可忽略
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

/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. 創(chuàng)建監(jiān)控用戶
創(chuàng)建一個(gè)用戶,開放你所要監(jiān)控的數(shù)據(jù)庫只讀權(quán)限給它,為了安全,把權(quán)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
使用創(chuàng)建的用戶能登錄查看相應(yīng)數(shù)據(jù)庫,則可進(jìn)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|

template1| postgres| UTF8 | en_US.UTF-8| en_US.UTF-8| =c/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(dǎo)入監(jiān)控模板
模板在Github上有:
https://github.com/cavaliercoder/libzbxpgsql/tree/master/templates
5. 主機(jī)鏈接模板,設(shè)置宏變量
{$PG_CONN} => host=localhost port=54321 user=monitoring connect_timeout=10
{$PG_DB} => wiseucmsg
有圖形出現(xiàn),則監(jiān)控成功。
