+title: OpenObserve
+description: Send logs to OpenObserve using Fluent Bit
+---
+
+# OpenObserve
+
+Use the OpenObserve output plugin to ingest logs into [OpenObserve](https://openobserve.ai/).
+
+Before you begin, you need an [OpenObserve account](https://cloud.openobserve.ai/), an
+`HTTP_User`, and an `HTTP_Passwd`. You can find these fields under **Ingestion** in
+OpenObserve Cloud. Alternatively, you can achieve this with various installation
+types as mentioned in the
+[OpenObserve documentation](https://openobserve.ai/docs/quickstart/)
+
+## Configuration Parameters

+| Host            | Required. The OpenObserve server where you are sending logs.                                                                                                                                                                                                                                                                                                                                                                           | `localhost` |
+| TLS             | Required: Enable end-to-end security using TLS. Set to `on` to enable TLS communication with OpenObserve.                                                                                                                                                                                                                                                                                                                                | `on`                            |
