+# nginx
+
+This module will monitor one or more nginx servers depending on configuration. Servers can be either local or remote.
+
+**Requirements:**
+ * nginx with configured 'ngx_http_stub_status_module'
+ * 'location /stub_status'
+
+Example nginx configuration can be found in 'python.d/nginx.conf'
+
+It produces following charts:
+
+1. **Active Connections**
+ * active
+
+2. **Requests** in requests/s
+ * requests
+
+3. **Active Connections by Status**
+ * reading
+ * writing
+ * waiting
+
+4. **Connections Rate** in connections/s
+ * accepts
+ * handled
+
+### configuration
+
+Needs only `url` to server's `stub_status`
+
+Here is an example for local server:
+
+```yaml
+update_every : 10
+priority     : 90100
+
+local:
+  url     : 'http://localhost/stub_status'
+```
+
+Without configuration, module attempts to connect to `http://localhost/stub_status`

+# netdata python.d.plugin configuration for nginx
+#
+# You must have ngx_http_stub_status_module configured on your nginx server for this
+# plugin to work. The following is an example config.
+# It must be located inside a server { } block.
+#  
+# location /stub_status {
+#   stub_status;
+#   # Security: Only allow access from the IP below.
+#   allow 192.168.1.200;
+#   # Deny anyone else
+#   deny all;
+#  }
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
+#     penalty: yes            # the JOB's penalty
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, this plugin also supports the following:
+#
+#     url: 'URL'       # the URL to fetch nginx's status stats
+#
+# if the URL is password protected, the following are supported:
+#
+#     user: 'username'
+#     pass: 'password'
+#
+# Example
+# 
+# RemoteNginx:
+#     name : 'Reverse_Proxy'
+#     url  : 'http://yourdomain.com/stub_status'
+#
+# "RemoteNginx" will show up in Netdata logs. "Reverse Proxy" will show up in the menu
+# in the nginx section.
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+
+localhost:
+  name : 'local'
