+- Call home client:
+
+    - The call home client sends daily usage statistics to Redis for operational insights. Reports include memory usage, shard information, enabled features, and other operational metrics.
+    
+    - The cluster collects usage data hourly by default.
+
+    - We recommend contacting [Redis support](https://redis.io/support/) before making changes to call home behavior.
+
+    - To change the data collection schedule, [update job scheduler settings]({{<relref "/operate/rs/references/rest-api/requests/job_scheduler#put-job-scheduler">}}) for `bdb_usage_report_job_settings` with a REST API request:
+
+        ```sh
+        PUT /v1/job_scheduler
+        {
+          "bdb_usage_report_job_settings": {

+            "cron_expression": "*/60 * * * *"
+          }
+        }
+        ```
+
+    - To stop the call home client from sending daily usage statistics to Redis, [update cluster services configuration
+]({{<relref "/operate/rs/references/rest-api/requests/cluster/services_configuration#put-cluster-services_config">}}) for `call_home_agent` with a REST API request:

     - Updates topology-related configurations of an active database and optimises the shards placement for the new configuration. Example configuration parameters include `memory_size`, `shards_count`, `avoid_nodes`, `shards_placement`, `bigstore_ram_size`, and `replication`.
