# uWSGI Input Plugin
|
||||
|
||||
The uWSGI input plugin gathers metrics about uWSGI using its [Stats
|
||||
Server](https://uwsgi-docs.readthedocs.io/en/latest/StatsServer.html).
|
||||
|
||||
## 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 uWSGI metrics.
|
||||
[[inputs.uwsgi]]
|
||||
## List with urls of uWSGI Stats servers. Url must match pattern:
|
||||
## scheme://address[:port]
|
||||
##
|
||||
## For example:
|
||||
## servers = ["tcp://localhost:5050", "http://localhost:1717", "unix:///tmp/statsock"]
|
||||
servers = ["tcp://127.0.0.1:1717"]
|
||||
|
||||
## General connection timeout
|
||||
# timeout = "5s"
|
||||
```
