# PgBouncer Input Plugin
2018-08-01 22:44:10 +00:00
2020-02-13 05:15:59 +00:00
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](https://pgbouncer.github.io/usage.html).
- PgBouncer minimum tested version: 1.5
### Configuration example
```toml
[[inputs.pgbouncer]]
## specify address via a url matching:
## postgres://[pqgotest[:password]]@localhost[/dbname]\
## ?sslmode=[disable|verify-ca|verify-full]
## or a simple string:
## host=localhost user=pqotest password=... sslmode=... dbname=app_production
##
## All connection parameters are optional.
##
address = "host=localhost user=pgbouncer sslmode=disable"
```
#### `address`
2018-08-01 22:44:10 +00:00
Specify address via a postgresql connection string:
`host=/run/postgresql port=6432 user=telegraf database=pgbouncer`
Or via an url matching:
2018-08-01 22:44:10 +00:00
`postgres://[pqgotest[:password]]@localhost[/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.
