To create a new token on the Splunk Cloud dashboard, open the Splunk Cloud dashboard in a browser, go to **Settings** > **Data Input** > **HTTP Event Collector**, and click **New Token** (on the upper-right corner of the page).                                                      |         |
     | `LOGS_REDACTION`               | Email addresses are automatically redacted before log entries are sent to Splunk Cloud Platform. To disable this redaction, set `LOGS_REDACTION` to `false`. The environment variable `SPLUNK_LOGS_REDACTION` is now deprecated in Cloud Foundry and is not supported for apps with Kubernetes deployment. Its use is not recommended. | `true`  |
     | `FLUENTBIT_LOGS_BUFFER_SIZE`   | Sets the maximum amount of data (in KB) that the TCP input plugin reads from the socket per read operation. Increasing this value can help to get rid of data flow delay, and errors related to queue buffer overflow.                                                                                                                 | `128`   |
-    | `FLUENTBIT_LOGS_MEM_BUF_LIMIT` | Defines the maximum total memory an input plugin can use for buffering log records before they are processed or flushed to storage/output.

+    Splunk Enterprise supports two types of indexes:
+         Events indexes. Events indexes impose minimal structure and can accommodate any type of data, including metrics data. Events indexes are the default index type. To get logs, you must use an event index as a default index within your HEC token.
+         Metrics indexes. Metrics indexes use a highly structured format to handle the higher volume and lower latency demands associated with metrics data. To get metrics, you must create an index called `mxmetrics` and add it into the allowed indexes list within your HEC token. More details on metrics indexes can be seen at [Splunk docs](https://help.splunk.com/en/splunk-cloud-platform/get-data-in/metrics/9.2.2406/introduction-to-metrics/overview-of-metrics).
