PgBouncer Input Plugin

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

[!NOTE] This plugin requires PgBouncer v1.5+.

⭐ Telegraf v1.8.0 🏷️ server, web 💻 all

Global configuration options <!-- @/docs/includes/plugin_config.md -->

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

toml
# 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:

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

or via an URL of the following form:

text
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.
