Discordapp.com

This is what you will get:

You need:

1. The incoming webhook URL as given by Discord. Create a webhook by following the official Discord documentation. You can use the same on all your Netdata servers (or you can have multiple if you like - your decision).
2. One or more Discord channels to post the messages to.

Set them in /etc/netdata/health_alarm_notify.conf (to edit it on your system run /etc/netdata/edit-config health_alarm_notify.conf), like this:

###############################################################################

# sending discord notifications

# note: multiple recipients can be given like this:

# "CHANNEL1 CHANNEL2 ..."

# enable/disable sending discord notifications

SEND_DISCORD="YES"

# Create a webhook by following the official documentation -

# https://support.discordapp.com/hc/en-us/articles/228383668-Intro-to-Webhooks

DISCORD_WEBHOOK_URL="https://discordapp.com/api/webhooks/XXXXXXXXXXXXX/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

# if a role's recipients are not configured, a notification will be send to

# this discord channel (empty = do not send a notification for unconfigured

# roles):

DEFAULT_RECIPIENT_DISCORD="alarms"

You can define multiple channels like this: alarms systems. You can give different channels per role using these (at the same file):

role_recipients_discord[sysadmin]="systems"

role_recipients_discord[dba]="databases systems"

role_recipients_discord[webmaster]="marketing development"

The keywords systems, databases, marketing, development are discordapp.com channels (they should already exist within your discord server).
