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

Configuration example

[[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=pqotest password=... sslmode=... dbname=app_production
  ##
  ## All connection parameters are optional.
  ##
  address = "host=localhost user=pgbouncer sslmode=disable"

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.
