+
+## Overview
+
+This collector monitors uWSGI metrics about requests, workers, memory and more.
+
+It collects every metric exposed from the stats server of uWSGI, either from the `stats.socket` or from the web server's TCP/IP socket.
+
+This collector is supported on all platforms.
+
+This collector supports collecting metrics from multiple instances of this integration, including remote instances.
+
+
+### Default Behavior
+
+#### Auto-Detection
+
+This collector will auto-detect uWSGI instances deployed on the local host, running on port 1717, or exposing stats on socket `tmp/stats.socket`.
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per uWSGI instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| uwsgi.requests | a dimension per worker | requests/s |
+| uwsgi.tx | a dimension per worker | KiB/s |
+| uwsgi.avg_rt | a dimension per worker | milliseconds |
+| uwsgi.memory_rss | a dimension per worker | MiB |
+| uwsgi.memory_vsz | a dimension per worker | MiB |
+| uwsgi.exceptions | exceptions | exceptions |
+| uwsgi.harakiris | harakiris | harakiris |
+| uwsgi.respawns | respawns | respawns |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+#### Enable the uWSGI Stats server
+
+Make sure that you uWSGI exposes it's metrics via a Stats server.
+
+Source: https://uwsgi-docs.readthedocs.io/en/latest/StatsServer.html
+
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `python.d/uwsgi.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config python.d/uwsgi.conf
+```
+#### Options
+
+There are 2 sections:
+
+* Global variables
+* One or more JOBS that can define multiple different instances to monitor.
+
+The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
+
+Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
+
+Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
+
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Sets the default data collection frequency. | 5 | False |
+| priority | Controls the order of charts at the netdata dashboard. | 60000 | False |
+| autodetection_retry | Sets the job re-check interval in seconds. | 0 | False |
+| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | False |
+| name | The JOB's name as it will appear at the dashboard (by default is the job_name) | job_name | False |
+| socket | The 'path/to/uwsgistats.sock' | no | False |
+| host | The host to connect to | no | False |
+| port | The port to connect to | no | False |
+
+</details>
+
+#### Examples
+
+##### Basic (default out-of-the-box)
+
+A basic example configuration, one job will run at a time. Autodetect mechanism uses it by default. As all JOBs have the same name, only one can run at a time.
+
+<details><summary>Config</summary>
+
+```yaml
+socket:
+  name     : 'local'
+  socket   : '/tmp/stats.socket'
+
+localhost:
+  name     : 'local'
+  host     : 'localhost'
+  port     : 1717
+
+localipv4:
+  name     : 'local'
+  host     : '127.0.0.1'
+  port     : 1717
+
+localipv6:
+  name     : 'local'
+  host     : '::1'
+  port     : 1717
+
+```
+</details>
+
+##### Multi-instance
+
+> **Note**: When you define multiple jobs, their names must be unique.
+
+Collecting metrics from local and remote instances.
+
+
+<details><summary>Config</summary>
+
+```yaml
+local:
+  name     : 'local'
+  host     : 'localhost'
+  port     : 1717
+
+remote:
+  name     : 'remote'
+  host     : '192.0.2.1'
+  port     : 1717

+```

+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `uwsgi` collector, run the `python.d.plugin` with the debug option enabled. The output
+should give you clues as to why the collector isn't working.
+
+- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
+  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
+
+  ```bash
+  cd /usr/libexec/netdata/plugins.d/
+  ```
+
+- Switch to the `netdata` user.
+
+  ```bash
+  sudo -u netdata -s
+  ```
+
+- Run the `python.d.plugin` to debug the collector:
+
+  ```bash
+  ./python.d.plugin uwsgi debug trace
+  ```
+
