+## From ipr-cnrs.netdata role
+
+# 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 discord guild (discordapp.com),
+# - messages to your telegram chat / group chat (telegram.org)
+# - sms messages to your cell phone or any sms enabled device (twilio.com)
+# - sms messages to your cell phone or any sms enabled device (messagebird.com)
+# - notifications to users on pagerduty.com
+#
+# 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, pushbullet, slack,
+# discord, telegram) via a proxy, set these to your proxy address:
+#export http_proxy="http://10.0.0.1:3128/"
+#export https_proxy="http://10.0.0.1:3128/"
+
+
+#------------------------------------------------------------------------------
+# notifications images
+#
+# 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
+# images from it.

+# NOTE ABOUT RECIPIENTS
+#
+# When you define recipients (all types):
+#
+#  - emails addresses
+#  - pushover user tokens
+#  - telegram chat ids
+#  - slack channels
+#  - discord channels
+#  - hipchat rooms
+#  - sms phone numbers
+#  - pagerduty.com (pd) services
+#
+# You can append |critical to limit the notifications to be sent.
+#
+# In these examples, the first recipient receives all the alarms
+# while the second one receives only the critical ones:
+#
+#  email      : "user1@example.com user2@example.com|critical"
+#  pushover   : "2987343...9437837 8756278...2362736|critical"
+#  telegram   : "111827421 112746832|critical"
+#  slack      : "alarms disasters|critical"
+#  discord    : "alarms disasters|critical"
+#  twilio     : "+15555555555 +17777777777|critical"
+#  messagebird: "+15555555555 +17777777777|critical"
+#  pd         : "<pd_service_key_1> <pd_service_key_2>|critical"
+#
+# If a recipient is set to empty string, the default recipient of the given
+# notification method (email, pushover, telegram, slack, etc) will be used.
+# To disable a notification, use the recipient called: disabled
+# This works for all notification methods (including the default recipients).
