Cortex is a CNCF incubation project used in several production systems including Amazon Managed Service for Prometheus (AMP) and it provides horizontally scalable, highly available, multi-tenant, long term storage for Prometheus.
You can use our example prometheus setup to test the Cortex integration
Go to Alert sources -> Alert sources and click on Create new alert source
Search for Cortex in the search field, click on the Cortex tile, and click on Next.
Give your alert source a name, optionally assign teams, and click Next.
Select an escalation policy by creating a new one or assigning an existing one.
Select your Alert grouping preference and click Continue setup. You may click Do not group alerts for now and change it later.
The next page shows additional settings such as customer alert templates or notification prioritiy. Click on Finish setup for now.
On the final page, a Cortex URL will be generated that you will need later in this guide.
In order to be able to use cortex alerts and receive notifications, you need first configure and start alertmanager
Install Prometheus Alertmanager in any way that suits your needs. For more information about the alertmanager installation process please visit https://prometheus.io/docs/alerting/latest/alertmanager/
Configure Alertmanager receivers in order to inform ilert every time there's an alert. In the example below replace the previously created Cortex URL:
You could also split alert to high and low priority by creating two alert sources accordingly
Install Cortex in any way that suits your needs.
Configure the Cortex alert rules in order to trigger alerts regarding the rule expression. For example:
Configure the Mimir ruler to send alerts to an external alertmanager and point the alert rules folder:
Will alerts in ilert be resolved automatically?
Yes, as soon as the Alertmanager sends a "RESOLVE" event, the associated alert is automatically resolved in ilert.
