Amazon SNS works kind of similarly to Netdata's own notification system, allowing dispatch of a single notification to multiple subscribers of different types. Among other things, SNS supports sending notifications to: + +* Email addresses. +* Mobile Phones via SMS. +* HTTP or HTTPS web hooks. +* AWS Lambda functions. +* AWS SQS queues. +* Mobile applications via push notifications. + +To get this working, you will need: + +* The Amazon Web Services CLI tools. Most distributions provide these with the package name `awscli`. +* An actual home directory for the user you run Netdata as, instead of just using `/` as a home directory. Setup of this is distribution specific. `/var/lib/netdata` is the recommended directory (because the permissions will already be correct) if you are using a dedicated user (which is how most distributions work). +* An Amazon SNS topic to send notifications to with one or more subscribers. The [Getting Started](https://docs.aws.amazon.com/sns/latest/dg/GettingStarted.html) section of the Amazon SNS documentation covers the basics of how to set this up. Make note of the Topic ARN when you create the topic. +* While not mandatory, it is highly recommended to create a dedicated IAM user on your account for netdata to send notifications.

If you want email notifications, use the native support, not SNS. + * If you need to change the notification format for SNS notifications, you can do so by specifying the format in `AWSSNS_MESSAGE_FORMAT` in the configuration. This variable supports all the same vairiables you can use in custom notifications. + * While Amazon SNS supports sending differently formatted messages for different delivery methods, netdata does not currently support this functionality. + +[]() diff --git a/health/notifications/discord/Makefile.inc b/health/notifications/discord/Makefile.inc new file mode 100644 index 0000000..03d0339 --- /dev/null +++ b/health/notifications/discord/Makefile.inc @@ -0,0 +1,12 @@ +# SPDX-License-Identifier: GPL-3.0-or-later + +# THIS IS NOT A COMPLETE Makefile +# IT IS INCLUDED BY ITS PARENT'S Makefile.am +# IT IS REQUIRED TO REFERENCE ALL FILES RELATIVE TO THE PARENT + +# install these files +dist_noinst_DATA += \ + discord/README.md \ + discord/Makefile.inc \ + $(NULL) + diff --git a/health/notifications/discord/README.md b/health/notifications/discord/README.md new file mode 100644 index 0000000..7694fef --- /dev/null +++ b/health/notifications/discord/README.md @@ -0,0 +1,46 @@ +# Discordapp.com + +This is what you will get: + + + +You need: + +1.

All major syslog daemons have the ability to filter +# messages based on both log level and facility, and can often also make +# routing decisions for messages based on both factors. +# +# On Linux, the eight log levels in decreasing order of severity are: +# emerg, alert, crit, err, warning, notice, info, debug +# +# By default, warnings will be logged at the warning level, critical +# alerts at the crit level, and clear notifications at the invo level. +# +# And the 19 facilities you can log to are: +# auth, authpriv, cron, daemon, ftp, lpr, mail, news, syslog, user, +# uucp, local0, local1, local2, local3, local4, local5, local6, and local7 +# +# By default, netdata alerts will be logged to the local6 facility. +# +# Depending on your distribution, this means that either all your +# netdata alerts will by default end up in the main system log (usually +# /var/log/messages), or they won't be logged to a file at all. +# Neither of these are likely to be what you actually want, but any +# configuration to change that needs to happen in the syslog daemon +# configuration, not here. + +# This controls which facility is used by defalt for logging.
