  "content": "You can view and set various cluster settings, such as cluster name, email service, time zone, and license, on the **Cluster \u003e Configuration** page.\n\n## General configuration tab\n\n### Upload cluster license key\n\nAfter purchasing a cluster license and if your account has the \"Admin\" role,\nyou can upload the cluster license key, either during initial\ncluster creation or at any time afterward. The license key defines various\ncluster settings, such as the maximum number of shards you can have in\nthe cluster. For more detailed information see [Cluster license\nkeys]().\n\n### View max number of allowed shards\n\nThe maximum number of allowed shards, which is determined by the cluster license\nkey, appears in the **Max number of shards** field in the **License** section.\n\n### View cluster name\n\nThe cluster name appears in the **Cluster name** field in the **License** section. This gives a\ncommon name that your team or Redis support can refer to. It is\nespecially helpful if you have multiple clusters.\n\n### Set time zone\n\nYou can change the **Time zone** field to ensure the date, time fields, and log entries in the Cluster Manager UI are shown in your preferred time zone. This setting doesn't affect other system logs or services.\n\n## Alert settings tab\n\nThe **Alert Settings** tab lets you configure alerts that are relevant to the entire cluster, such as alerts for cluster utilization, nodes, node utilization, security, and database utilization.\n\nYou can also configure email server settings and [send alerts by email]() to relevant users.\n\n### Configure email server settings\n\nTo enable email alerts:\n\n1. Enter your email\nserver details in the **Email server settings** section.\n\n1. Select a connection security method:\n\n    - TLS/SSL \n\n    - STARTTLS\n    \n    - None\n\n1. Send a test email to verify your email server settings.\n",
