+## Using Logstash to Ingest Data into OpenObserve
+

+
+Yes, you can use Logstash to ingest data into OpenObserve since it allows you to collect, parse, and transform data before sending it to various outputs. By integrating it with OpenObserve, you can ensure a seamless transition from your existing ELK stack to OpenObserve without disrupting your current workflow.
+
+### Why Use Logstash with OpenObserve?
+If you’re migrating from ELK to OpenObserve, reusing your existing Logstash configuration can significantly reduce complexity. Logstash's flexibility allows it to send data to OpenObserve without requiring major changes in your pipeline.
+
+### Logstash Output Configuration for OpenObserve
+To start sending data from Logstash to OpenObserve, simply use the following output configuration in your Logstash pipeline:
+
+```bash
+output {
+  http {
+    url => "<openobserve_ingestion_endpoint>"
+    http_method => "post"
+    format => "json_batch"
+    headers => {
+      "Authorization" => "Basic <openobserve_token>"
+      "Content-Type" => "application/json"
+    }
+  }
+}
+
+```
