Matrix

Send notifications to Matrix network rooms using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.

Setup

Prerequisites

• The url of the homeserver (https://homeserver:port).
• Credentials for connecting to the homeserver, in the form of a valid access token for your account (or for a dedicated notification account). These tokens usually don't expire.
• The Room ids that you want to sent the notification to.
• Access to the terminal where Netdata Agent is running

Configuration

Options

The following options can be defined for this notification

Config Options

Option	Description	Default	Required
SEND_MATRIX	Set SEND_MATRIX to YES	YES	yes
MATRIX_HOMESERVER	set MATRIX_HOMESERVER to the URL of the Matrix homeserver.		yes
MATRIX_ACCESSTOKEN	Set MATRIX_ACCESSTOKEN to the access token from your Matrix account.		yes
DEFAULT_RECIPIENT_MATRIX	Set DEFAULT_RECIPIENT_MATRIX to the Rooms you want the alert notifications to be sent to. The format is !roomid:homeservername.		yes

MATRIX_ACCESSTOKEN

To obtain the access token, you can use the following curl command:

curl -XPOST -d '{"type":"m.login.password", "user":"example", "password":"wordpass"}' "https://homeserver:8448/_matrix/client/r0/login"

DEFAULT_RECIPIENT_MATRIX

The Room ids are unique identifiers and can be obtained from the Room settings in a Matrix client (e.g. Riot).

You can define multiple Rooms like this: !roomid1:homeservername !roomid2:homeservername.

All roles will default to this variable if left unconfigured.

You can have different Rooms per role, by editing DEFAULT_RECIPIENT_MATRIX with the !roomid:homeservername you want, in the following entries at the bottom of the same file:

role_recipients_matrix[sysadmin]="!roomid1:homeservername"
role_recipients_matrix[domainadmin]="!roomid2:homeservername"
role_recipients_matrix[dba]="!roomid3:homeservername"
role_recipients_matrix[webmaster]="!roomid4:homeservername"
role_recipients_matrix[proxyadmin]="!roomid5:homeservername"
role_recipients_matrix[sitemgr]="!roomid6:homeservername"

via File

The configuration file name for this integration is health_alarm_notify.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config health_alarm_notify.conf

Examples

Basic Configuration

#------------------------------------------------------------------------------
# Matrix notifications

SEND_MATRIX="YES"
MATRIX_HOMESERVER="https://matrix.org:8448"
MATRIX_ACCESSTOKEN="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
DEFAULT_RECIPIENT_MATRIX="!XXXXXXXXXXXX:matrix.org"

Troubleshooting

Test Notification

You can run the following command by hand, to test alerts configuration:

# become user netdata
sudo su -s /bin/bash netdata

# enable debugging info on the console
export NETDATA_ALARM_NOTIFY_DEBUG=1

# send test alarms to sysadmin
/usr/libexec/netdata/plugins.d/alarm-notify.sh test

# send test alarms to any role
/usr/libexec/netdata/plugins.d/alarm-notify.sh test "ROLE"

Note that this will test all alert mechanisms for the selected role.
