+# This class will install the necessary configuration for the supervisord integration
+#
+# Parameters:
+#   servername
+#   socket
+#       Optional. The socket on which supervisor listen for HTTP/XML-RPC requests. 
+#   hostname
+#       Optional. The host where supervisord server is running. 
+#   port
+#       Optional. The port number.
+#   username

+#       If not specified, the check will monitor all processes. 
+#   server_check
+#       Optional. Service check for connections to supervisord server.

+#
+# Sample Usage:
+#
+# class { 'datadog_agent::integrations::supervisord':

+#   There are two ways to get started with the supervisord check.
+#
+#   You can configure inet_http_server in /etc/supervisord.conf. Below is an
+#   example inet_http_server configuration:
+#
+#       [inet_http_server]
+#       port:localhost:9001
+#       username:user  # optional
+#       password:pass  # optional
+#
+#   OR, you can use supervisorctl socket to communicate with supervisor.
+#   If supervisor is running as root, make sure chmod property is set
+#   to a permission accessible to non-root users. See the example below:
+#
+#       [supervisorctl]
+#       serverurl=unix:///var/run//supervisor.sock
+#
+#       [unix_http_server]
+#       file=/var/run/supervisor.sock
+#       chmod=777
+#
+#  Reload supervisor, specify the inet or unix socket server information
+#  in this yaml file along with an optional list of the processes you want
+#  to monitor per instance, and you're good to go!
+#
+#  See http://supervisord.org/configuration.html for more information on
+#  configuring supervisord sockets and inet http servers.
+#
+
+#   - name: server0    # Required. An arbitrary name to identify the supervisord server
+#     host: localhost  # Optional. Defaults to localhost. The host where supervisord server is running
+#     port: 9001       # Optional. Defaults to 9001. The port number.
+#     user: user       # Optional. Required only if a username is configured.
+#     pass: pass       # Optional. Required only if a password is configured.
+#     proc_regex:      # Optional. Regex pattern[s] matching the names of processes to monitor
+#      - 'myprocess-\d\d$'
+#     proc_names:      # Optional. The process to monitor within this supervisord instance.
+#      - apache2       #           If not specified, the check will monitor all processes.
+#      - webapp
+#      - java
+#   - name: server1
+#     host: localhost
+#     port: 9002
+#   - name: server2
+#     socket: unix:///var/run//supervisor.sock
+#     host: http://127.0.0.1        # Optional. Defaults to http://127.0.0.1
