| `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. Limits memory which can be consumed by the Fluentbit agent. | `50MB` |

**Splunk supports two types of indexes:**

* **Event indexes**: These are the default index type and impose minimal structure, allowing them to store any kind of data, including metrics. To ingest logs, you must configure an event index as the default index in your HEC token.

* **Metrics indexes**: These use a highly structured format designed for high-volume, low-latency metrics data. To ingest metrics, create an index named `mxmetrics` and add it to the list of allowed indexes in your HEC token. For more information, refer to the [Splunk documentation](https://help.splunk.com/en/splunk-cloud-platform/get-data-in/metrics/9.2.2406/introduction-to-metrics/overview-of-metrics).
