Using Alertmanager for notifications
To configure the built-in Alertmanager to send notifications, you need to open a TCP port for the Alertmanager API to be accessible from the outside.
To open a port for the Alertmanager API
- On the Infrastructure > Networks screen, click Edit and then Create traffic type.
In the Create traffic type window, specify a custom name in the Name field and 9093 in the Port field. Then, click Create.
- Click Assign to networks next to the Custom traffic types section, and then add the created traffic type to your public network by selecting the corresponding check box.
- Click Save to apply the changes.
You can now access the Alertmanager API at http://<admin_panel_IP_address>:9093. For more information on configuring Alertmanager, refer to its documentation.
