# 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
#### 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](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config health_alarm_notify.conf
```
#### Options
The following options can be defined for this notification
Config Options
| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| SEND_MATRIX | Set `SEND_MATRIX` to YES | YES | True |
| MATRIX_HOMESERVER | set `MATRIX_HOMESERVER` to the URL of the Matrix homeserver. | | True |
| MATRIX_ACCESSTOKEN | Set `MATRIX_ACCESSTOKEN` to the access token from your Matrix account. | | True |
| DEFAULT_RECIPIENT_MATRIX | Set `DEFAULT_RECIPIENT_MATRIX` to the rooms you want the alert notifications to be sent to. The format is `!roomid:homeservername`. | | True |
##### 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:
```conf
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"
```
#### Examples
##### Basic Configuration
```yaml
#------------------------------------------------------------------------------
# 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:
```bash
# 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.
