PgBouncer Input Plugin

The pgbouncer plugin provides metrics for your PgBouncer load balancer.

More information about the meaning of these metrics can be found in the PgBouncer Documentation.

  • PgBouncer minimum tested version: 1.5

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"]

address

Specify address via a postgresql connection string:

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

Or via an url matching:

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. This dbname is just for instantiating a connection with the server and doesn't restrict the databases we are trying to grab metrics for.
