Unable to manage Grafana alerts silences

Question

We are using AMP and AMG for our observability needs. Currently, we're not using the Alert Manager infra provided by Prometheus and are only using the Grafana's unified alerting infrastructure in v9.4.

I'm able to create alert rules and see the alerts come through to our Slack, but for some reason, we cannot access the "Silences" tab to manage silencing of our alerts. What could be causing this?

**Working as expected in the Alert Groups tab**

**Nothing showing up in Silences tab**

Hello, the above seems to be pertaining to  Grafana Labs, which is  out of scope of AWS Premium Support. However, you could refer to https://grafana.com/docs/grafana/latest/alerting/manage-notifications/create-silence/ . If that doesn't help, you may want to reach out to Grafana support at https://grafana.com/contact.

Hello,

In order to manage alerts from external data sources, you need to configure an [external Alertmanager](https://docs.aws.amazon.com/grafana/latest/userguide/v9-alerting-setup-alertmanager.html) in Grafana.

Please note that you can use a single [alertmanager](https://docs.aws.amazon.com/grafana/latest/userguide/v9-alerting-managenotifications-alertmanager.html) to receive all your Grafana, Loki, Mimir, and Prometheus alerts with an external Alertmanager. This external Alertmanager can be configured and administered from within Grafana itself.

That being said, please try adding an external Alertmanager and check again if you can enable [Silencing](https://docs.aws.amazon.com/grafana/latest/userguide/v9-alerting-silences.html) for your Prometheus alert notifications.

Hope you find this useful. Comment here if you have any additional questions.
