pg_monz 的简介

Directory/File name                         Function
Template                                      Monitoring template
usr-local-bin/*                             Backend scripts
usr-local-etc/*                             Configuration files for backend scripts
zabbix-agentd.d/userparameter_pgsql.conf      UserParameter configuration file for Zabbix Agent

Backend scripts
Usr-local-bin directory includes some backend scripts. These scripts are called by UserParameters which are defined at userparameter_pgsql.conf.

Configuration files
Usr-local-etc directory includes two configuration files. These scripts are used to executing backend scripts.

pgsql_funcs.conf : Configuration file of connection information to PostgreSQL server
pgpool_funcs.conf : Configuration file of connection information to pgpool-II

[Note] At version 1.0, this information is set to Zabbix MACRO. But, at version 2.0, this information is set to above files.

pg_monz 的模版说明

Template directory includes the following 5 monitoring template xml.

Template name                           Use
Template_App_PostgreSQL.xml             Monitoring for single PostgreSQL server
Template_App_PostgreSQL_SR.xml          Monitoring for Streaming Replication
Template_App_PostgreSQL_SR_Cluster.xml  Monitoring for the whole Streaming Replication cluster
Template_App_pgpool-II.xml              Monitoring for pgpool-II (pgpool-II 3.5 or earlier)
Template_App_pgpool-II-36.xml             Monitoring for pgpool-II (pgpool-II 3.6 or later)
Template_App_pgpool-II_watchdog.xml     Monitoring for the whole pgpool-II cluster

pg_monz下载、安装

Requirements
pg_monz requires the following software products: Also note that Zabbix Agent and Zabbix Sender must be installed on the monitoring target server since it utilizes the functions of Zabbix Agent and Zabbix Sender for acquiring PostgreSQL information.

Software name                               Version
Zabbix Server,Zabbix Agent,Zabbix Sender    2.0 or later
PostgreSQL                                9.2 or later
pgpool-II                                   3.4.0 or later

Since bc command is executed in pg_monz backend scripts, bc command must be installed on the monitoring target server.

安装 zabbix-sender

# apt install zabbix-sender bc# dpkg -l |grep -i zabbix
ii  zabbix-agent                        1:3.4.13-1+xenial                          amd64        Zabbix network monitoring solution - agent
ii  zabbix-release                      3.4-1+xenial                               all          Zabbix official repository configuration
ii  zabbix-sender                       1:3.4.13-1+xenial                          amd64        Zabbix network monitoring solution - sender

从git下载,node1、node2上都需要操作

# cd /tmp
# wget https://github.com/pg-monz/pg_monz/archive/2.1.tar.gz
# tar -zxvf ./2.1.tar.gz
# cd pg_monz-2.1/

zabbix 导入监控模版

zabbix web 页面操作

Configuration -> Templates -> Import

导入 pg_monz 模版 Template App PostgreSQL.xml、Template_App_PostgreSQL_SR.xml、Template_App_PostgreSQL_SR_Cluster.xml

zabbix 主机配置模板

zabbix web 页面操作
Configuration -> Host groups -> Create host group

输入 PostgreSQL,输入的这个名字对应 Template_App_PostgreSQL_SR_Cluste 模版的 {$PG_HOST_GROUP} 值

Configuration -> Hosts

点击某台机器，进去选择 Templates，
点击Select，选中 Template App PostgreSQL、Template_App_PostgreSQL_SR 或者Template_App_PostgreSQL_SR_Cluster ,点击页下面的 Select
点击 Add
点击 Update
