Telegraf Input Plugin: PostgreSQL

PostgreSQL monitoring tracks your metrics to manage performance. This plugin provides metrics for your PostgreSQL database. It currently works with PostgreSQL versions 8.1+. It uses data from the built in pg_stat_database and pg_stat_bgwriter views. The metrics recorded depend on your version of PostgreSQL.

PostgreSQL Basics

An enterprise class database, PostgreSQL boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, asynchronous replication, nested transactions (savepoints), online/hot backups, a sophisticated query planner/optimizer, and write ahead logging for fault tolerance.

PostgreSQL is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, ODBC, among others.
