Different IT departments have different requirements when it comes to what is considered an issue that needs alerting. Storage Grid understands this and this is why storage grid not only has a variety of Prometheus metrics to monitor but also a highly customizable alert system. Custom alerts for storage grid can be created to trigger on specific conditions that are relevant to your business processes and thresholds. Creating a custom alert requires writing a Prometheus expression to determine the condition that triggers the alert. These expressions are based on our storage grid metrics. For you to better understand customizing alerts, you should first know what metrics are available and where to successfully validate your query expressions before creating a custom alert. You can define a custom alert by creating expressions utilizing the storage grid metrics. To see the available list of metrics, you can query the grid manager API. We have API documentation available under this question mark and API docs. The API operation to list all available metrics can be found here under metrics. For example, you can execute this API call, list all available metric names, and save the response body for a full list of storage grid metrics. Now that you have a list of metrics, you can pick one to query and see its value. You can easily query a metric via API or you can access the Prometheus UI and form the query. In the main storage grid UI, click support and metrics and then access the Prometheus UI using the link provided. In the Prometheus UI, you can easily test query a metric or a Prometheus expression before using it in a custom alert as a condition. For example, we can query the per node CPU use percentage and view the output in console format or as a graph. These storage metrics are integral to creating your custom alerts. Now that you understand where you can list query and test expressions, let's go back to discussing custom alerts.are Storage Grid's primary system to notify the administrator of any problems. By default, Storage Grid supplies predefined alert rules that cover most problems. However, there are cases where an administrator would like to create a custom alert for a specific situation. You can create a custom alert by going to the alert rules page and clicking create custom rule. Within this form, all values are customizable.The name, the description, the recommended actions, all three conditions, and the duration. As an example, I have created a custom alert that will track CPU utilization. We can tell it's a custom alert because in the right hand column it says custom. Since everything is customizable, you can enter your own unique name, description, and recommended action. In conclusion, creating a custom alert rule requires understanding and using our storage grid metrics. This can be a powerful feature that allows admins to target their specific monitoring needs.
