PostgreSQL by Zabbix agent
Overview
This template is designed for the deployment of PostgreSQL monitoring by Zabbix via Zabbix agent and uses user parameters to run SQL queries with the psql
command-line tool.
Requirements
Zabbix version: 6.4 and higher.
Tested versions
This template has been tested on:
- PostgreSQL 10-15
Configuration
Zabbix should be configured according to the instructions in the Templates out of the box section.
Setup
Note:
- The template requires
pg_isready
andpsql
utilities to be installed on the same host with Zabbix agent.
- Deploy Zabbix agent and create the PostgreSQL user for monitoring (
<password>
at your discretion) with proper access rights to your PostgreSQL instance.
For PostgreSQL version 10 and above:
CREATE USER zbx_monitor WITH PASSWORD '<PASSWORD>' INHERIT;
GRANT pg_monitor TO zbx_monitor;
For PostgreSQL version 9.6 and below:
CREATE USER zbx_monitor WITH PASSWORD '<PASSWORD>';
GRANT SELECT ON pg_stat_database TO zbx_monitor;
-- To collect WAL metrics, the user must have a `superuser` role.
ALTER USER zbx_monitor WITH SUPERUSER;
- Copy the
postgresql/
directory to thezabbix
user home directory -/var/lib/zabbix/
. Thepostgresql/
directory contains the files with SQL queries needed to obtain metrics from PostgreSQL instance.
If the home directory of the zabbix
user doesn't exist, create it first:
mkdir -m u=rwx,g=rwx,o= -p /var/lib/zabbix
chown zabbix:zabbix /var/lib/zabbix
- Copy the
template_db_postgresql.conf
file, containing user parameters, to the Zabbix agent configuration directory/etc/zabbix/zabbix_agentd.d/
and restart Zabbix agent service.
Note: if you want to use SSL/TLS encryption to protect communications with the remote PostgreSQL instance, you can modify the connection string in user parameters. For example, to enable required encryption in transport mode without identity checks you could append ?sslmode=required
to the end of the connection string for all keys that use psql
:
UserParameter=pgsql.bgwriter[*], psql -qtAX postgresql://"$3":"$4"@"$1":"$2"/"$5"?sslmode=required -f "/var/lib/zabbix/postgresql/pgsql.bgwriter.sql"
Consult the PostgreSQL documentation about protection modes
and client connection parameters
.
Also, it is assumed that you set up the PostgreSQL instance to work in the desired encryption mode. Check the PostgreSQL documentation
for details.
- Edit the
pg_hba.conf
configuration file to allow connections for the userzbx_monitor
. For example, you could add one of the following rows to allow local TCP connections from the same host:
# TYPE DATABASE USER ADDRESS METHOD
host all zbx_monitor localhost trust
host all zbx_monitor 127.0.0.1/32 md5
host all zbx_monitor ::1/128 scram-sha-256
For more information please read the PostgreSQL documentation https://www.postgresql.org/docs/current/auth-pg-hba-conf.html
.
-
Specify the host name or IP address in the
{$PG.HOST}
macro. Adjust the port number with{$PG.PORT}
macro if needed. -
Set the password that you specified in step 1 in the macro
{$PG.PASSWORD}
.
