# 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](https://pgbouncer.github.io/usage.html).
|
||
|
|
|
||
|
|
- PgBouncer minimum tested version: 1.5
|
||
|
|
|
||
|
|
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
||
|
|
|
||
|
|
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][CONFIGURATION.md] for more details.
|
||
|
|
|
||
|
|
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
```toml @sample.conf
|
||
|
|
# 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:
|
||
|
|
|
||
|
|
```text
|
||
|
|
host=/run/postgresql port=6432 user=telegraf database=pgbouncer
|
||
|
|
```
|
||
|
|
|
||
|
|
Or via an url matching:
|
||
|
|
|
||
|
|
```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. This dbname is just for instantiating a connection with
|
||
|
|
the server and doesn't restrict the databases we are trying to grab metrics for.
|
||
|
|
|
||
|
