+lines are creates dynamically based on how many workers are there
+
+Following charts are drawn:
+
+1. **Requests**
+ * requests per second
+ * transmitted data
+ * average request time
+
+2. **Memory**
+ * rss
+ * vsz
+
+3. **Exceptions**
+4. **Harakiris**
+5. **Respawns**
+
+### configuration
+
+```yaml
+socket:
+ name : 'local'
+ socket : '/tmp/stats.socket'
+
+localhost:
+ name : 'local'
+ host : 'localhost'
+ port : 1717
+```
+
+When no configuration file is found, module tries to connect to TCP/IP socket: `localhost:1717`.

+# netdata python.d.plugin configuration for uwsgi
+#
+# 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, uwsgi also supports the following:
+#
+# socket: 'path/to/uwsgistats.sock'
+#
+# or
+# host: 'IP or HOSTNAME' # the host to connect to
+# port: PORT # the port to connect to
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
