+# Configuration for alarm notifications
+#
+# This configuration is used by: alarm-notify.sh
+# changes take effect immediately (the next alarm will use them).
+#
+# alarm-notify.sh can send:
+# - e-mails (using the sendmail command),
+# - push notifications to your mobile phone (pushover.net),
+# - messages to your slack team (slack.com),
+# - messages to your telegram chat / group chat (telegram.org)
+#
+# The 'to' line given at netdata alarms defines a *role*, so that many
+# people can be notified for each role.
+#
+# This file is a BASH script itself.

+# proxy configuration
+#
+# If you need to send curl based notifications (pushover, slack, telegram)
+# via a proxy, set these to your proxy address:

+#export https_proxy="http://10.0.0.1:3128/"

+#
+# Images in notifications need to be downloaded from an Internet facing site.
+# To allow notification providers fetch the icons/images, by default we set
+# the URL of the global public netdata registry.
+# If you have an Internet facing netdata (or you have copied the images/ folder
+# of netdata to your web server), set its URL here, to fetch the notification

+#
+# You can append |critical to limit the notifications to be sent.

+#  slack   : "alarms disasters|critical"
+#
+# If a recipient is set to empty string, the default recipient of the given

+# netdata python.d.plugin configuration for RetroShare
+#
+# 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: 5
+
+# ----------------------------------------------------------------------
+# 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: 5       # the JOB's number of restoration attempts
+#
+# Additionally to the above, RetroShare also supports the following:
+#
+# - url: 'url'         # the URL to the WebUI
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+
+localhost:
+    name: 'local'
+    url: 'http://localhost:9090'
