      "text": "The Redis Software cluster nodes host a range of services that support the cluster processes.\nIn most deployments, either all of these services are required,\nor there are enough memory resources on the nodes for the database requirements.\n\nIn a deployment with limited memory resources, certain services can be disabled from API endpoint to free system memory or using the `rladmin` command.\nBefore you turn off a service, make sure that your deployment does not depend on that service.\nAfter you turn off a service, you can re-enable in the same way.\n\nThe services that you can turn off are:\n\n- RS Admin Console - `cm_server`\n- Logs in CSV format - `stats_archiver`\n- [LDAP authentication](https://redis.io/docs/latest/operate/rs/security/access-control/ldap) - `saslauthd`\n- [Discovery service](https://redis.io/docs/latest/operate/rs/networking/cluster-dns)- `mdns_server`, `pdns_server`\n- [Active-Active databases](https://redis.io/docs/latest/operate/rs/databases/active-active) - `crdb_coordinator`, `crdb_worker`\n- Alert Manager - `alert_mgr` (For best results, disable only if you have an alternate alert system.)\n\nTo turn off a service with the `rladmin cluster config` command, use the `services` parameter and the name of the service, followed by `disabled`.\n[code example]\n\nTo turn off a service with the API, use the [`PUT /v1/services_configuration`](https://redis.io/docs/latest/operate/rs/references/rest-api/requests/cluster/services_configuration#put-cluster-services_config) endpoint\nwith the name of the service and the operating mode (enabled/disabled) in JSON format.\n\nFor example:\n- To turn off the Redis Software Cluster Manager UI, use this PUT request:\n\n    [code example]\n\n- To turn off the CRDB services and enable the `stats_archiver` for cluster component statistics, use this PUT request:\n\n    [code example]"
