Send a dummy alert to AlertManager:
.. tab-set::
.. tab-item:: Robusta CLI
If you have the Robusta CLI installed, you can send a test alert using the following command:
.. code-block:: bash
robusta demo-alert
.. tab-item:: Robusta UI
In the Robusta UI, go to the "Clusters" tab, choose the right cluster and click "Simulate Alert".

Then
1. Check **Send alert with no resource**.
2. Provide a name for the alert in the **Alert name (identifier)** field (e.g., "Testing Prod AlertManager").
3. Select **Alert Manager** under the "Send alert to" section.
4. Click the **Simulate Alert** button to send the test alert.

If everything is setup properly, this alert will reach Robusta. It will show up in the Robusta UI, Slack, and other configured sinks.
Note
It might take a few minutes for the alert to arrive due to AlertManager's group_wait and group_interval settings. More info here.
.. details:: I configured AlertManager, but I'm not receiving alerts?
:class: warning
Try sending a demo-alert as described above. If nothing arrives, check:
1. AlertManager UI status page - verify that your config was picked up
2. kube-prometheus-operator logs (if relevant)
3. AlertManager logs
Reach out on `Slack <https://bit.ly/robusta-slack>`_ for assistance.
.. details:: Robusta isn't mapping alerts to Kubernetes resources
:class: warning
Robusta enriches alerts with Kubernetes and log data using Prometheus labels for mapping.
Standard label names are used by default. If your setup differs, you can
:ref:`customize this mapping <Relabel Prometheus Alerts>` to fit your environment.
