postgresqlHow can I monitor PostgreSQL performance using Zabbix?

Zabbix is a powerful monitoring tool that can be used to monitor the performance of PostgreSQL databases. The following steps outline how to set up Zabbix for PostgreSQL monitoring:

1. Install the Zabbix Agent on the PostgreSQL server.
2. Create a Zabbix user on the PostgreSQL server.
3. Configure the Zabbix Agent to connect to the PostgreSQL server.
4. Create a Zabbix template for PostgreSQL monitoring.
5. Create a Zabbix item to monitor PostgreSQL performance.

Example code for creating a Zabbix item to monitor PostgreSQL performance:

UserParameter=postgresql.performance[*],psql -U zabbix_user -d postgres -c "SELECT * FROM pg_stat_activity WHERE state='active'"

The code above creates a Zabbix item that will query the pg_stat_activity table in the PostgreSQL database and return the active connections.
