+# haproxy
+
+Module monitors frontend and backend metrics such as bytes in, bytes out, sessions current, sessions in queue current.
+And health metrics such as backend servers status (server check should be used).
+
+Plugin can obtain data from url **OR** unix socket.
+
+**Requirement:**
+Socket MUST be readable AND writable by netdata user.
+
+It produces:
+
+1. **Frontend** family charts
+ * Kilobytes in/s
+ * Kilobytes out/s
+ * Sessions current
+ * Sessions in queue current
+
+2. **Backend** family charts
+ * Kilobytes in/s
+ * Kilobytes out/s
+ * Sessions current
+ * Sessions in queue current
+
+3. **Health** chart
+ * number of failed servers for every backend (in DOWN state)
+
+
+### configuration
+
+Sample:
+
+```yaml
+via_url:
+  user       : 'username' # ONLY IF stats auth is used
+  pass       : 'password' # # ONLY IF stats auth is used
+  url     : 'http://ip.address:port/url;csv;norefresh'
+```
+
+OR
+
+```yaml
+via_socket:
+  socket       : 'path/to/haproxy/sock'
+```
+
+If no configuration is given, module will fail to run.

+# netdata python.d.plugin configuration for haproxy
+#
+# 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
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# 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
+#     retries: 60             # the JOB's number of restoration attempts
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, haproxy also supports the following:
+#
+# IMPORTANT: socket MUST BE readable AND writable by netdata user
+#
+#     socket: 'path/to/haproxy/sock'
+#
+#  OR
+#     url: 'http://<ip.address>:<port>/<url>;csv;norefresh'
+#     [user: USERNAME] only if stats auth is used
+#     [pass: PASSWORD] only if stats auth is used
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+
+#via_url:
+# user : 'admin'
+# pass : 'password'
+# url : 'http://127.0.0.1:7000/haproxy_stats;csv;norefresh'
+
+#via_socket:
+# socket: '/var/run/haproxy/admin.sock'
