PgBouncer Input Plugin

This plugin collects metrics from a PgBouncer load balancer instance. Check the documentation for available metrics and their meaning.

This plugin requires PgBouncer v1.5+.

Introduced in: Telegraf v1.8.0 Tags: server, web OS support: all

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read metrics from one or many pgbouncer servers
[[inputs.pgbouncer]]
  ## specify address via a url matching:
  ##   postgres://[pqgotest[:password]]@host:port[/dbname]\
  ##       ?sslmode=[disable|verify-ca|verify-full]
  ## or a simple string:
  ##   host=localhost port=5432 user=pqgotest password=... sslmode=... dbname=app_production
  ##
  ## All connection parameters are optional.
  ##
  address = "host=localhost user=pgbouncer sslmode=disable"

  ## Specify which "show" commands to gather metrics for.
  ## Choose from: "stats", "pools", "lists", "databases"
  # show_commands = ["stats", "pools"]

To specify the address use either a PostgreSQL connection string:

host=/run/postgresql port=6432 user=telegraf database=pgbouncer

or via an URL of the following form:

postgres://[pqgotest[:password]]@host:port[/dbname]?sslmode=[disable|verify-ca|verify-full]

All connection parameters are optional.

Without the dbname parameter, the driver will default to a database with the same name as the user. The dbname is for instantiating a connection with the server only and doesn’t restrict access to the databases queried.

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
