Hello,

Amazon Managed Grafana will perform a planned maintenance for your workspace on the weekend of September 16, 2023 between 8:00 AM and 5:00 PM PDT.

During this time the following will take place:

1. Your Amazon Managed Grafana workspace will be in "updating" state. 2. Logged-in users will see a banner in the workspace that says "Grafana is temporarily in read-only mode while it is updating". 3. Workspace users will NOT be able to create, edit, or delete any dashboards, data sources, alerts, or teams for up to 45 minutes. You will continue to receive alerts and view dashboards.

Amazon Managed Grafana recently launched support for updating your workspace version to 9.4. You can preempt this maintenance by updating your workspace to version 9.4 anytime before September 16, 2023, and gain access to the feature list in the following section.

Amazon Managed Grafana v9.4 new features:

* Plugin enhancements to support Amazon CloudWatch cross-account querying. * Amazon OpenSearch Serverless, querying multiple asset properties from AWS IoT Sitewise. * Query result reuse and async queries for Athena. * Prometheus and Loki query builders that make it even easier to create and modify queries for your data sources. * Service accounts to provide a secure and efficient way to automate tasks within your Grafana instance.

For instructions on how to update your workspace(s), see Amazon Managed Grafana service documentation [1]. We recommend testing the newer version in a non-production environment before updating a production workspace. You can also migrate your dashboards and data sources from your existing workspace to a new v9.4 workspace for testing, using the Amazon Managed Grafana Migrator tool [2].

Note that any Amazon Managed Grafana workspaces in CREATE_FAILED or DELETE_FAILED state will be deleted as a part of the maintenance. If you wish to resolve these states, or have concerns deleting these workspaces, please reach out to AWS Support [3] by September 11, 2023.
