 # Event analytics
 
-Event analytics in Observability is where you can use [Piped Processing Language]({{site.url}}{{site.baseurl}}/search-plugins/sql/ppl/index) (PPL) queries to build and view different visualizations of your data.
+Event analytics in OpenSearch Observability allow you to create data visualizations using [Piped Processing Language]({{site.url}}{{site.baseurl}}/search-plugins/sql/ppl/index/) (PPL) queries.
 
 ## Getting started with event analytics
 
-To get started, choose **Observability** in OpenSearch Dashboards and then choose **Event analytics**. If you want to start exploring without adding any of your own data, choose **Add samples**, and Dashboards adds sample visualizations you can interact with.

+### OpenSearch Dashboards Query Assistant
+
+This is an experimental feature and is not recommended for use in a production environment. For updates on the progress of the feature or if you want to leave feedback, see the associated [OpenSearch forum thread](https://forum.opensearch.org/t/feedback-opensearch-assistant/16741).    
+{: .warning}
+
+To simplify query building, the **OpenSearch Assistant** toolkit offers an assistant that converts natural language queries into PPL. A screenshot is shown in the following image.

+
+#### Enabling Query Assistant
+
+To enable **Query Assistant** in OpenSearch Dashboards, locate your copy of the `opensearch_dashboards.yml` file and set the following option:
+
+```
+observability.query_assist.enabled: true
+observability.query_assist.ppl_agent_name: "PPL agent"
+```
+
+To enable summarization of responses, locate your copy of the `opensearch_dashboards.yml` file and set the following option:
+
+```
+observability.summarize.enabled: true
+observability.summarize.response_summary_agent_name: "Response summary agent"
+observability.summarize.error_summary_agent_name: "Error summary agent"
+```
+
+#### Setting up Query Assistant
+
+To set up **Query Assistant**, follow the steps in the [Getting started guide](https://github.com/opensearch-project/dashboards-assistant/blob/main/GETTING_STARTED_GUIDE.md) on GitHub. This guide provides step-by-step setup instructions for **OpenSearch Assistant** and **Query Assistant**. To set up **Query Assistant** only, use the `query-assist-agent` template included in the guide.
 
 ## Saving a visualization
 
-After Dashboards generates a visualization, you must save it if you want to return to it at a later time or if you want to add it to an [operational panel]({{site.url}}{{site.baseurl}}/observing-your-data/operational-panels).
+After Dashboards generates a visualization, save it if you want to revisit it or include it in an [operational panel]({{site.url}}{{site.baseurl}}/observing-your-data/operational-panels). To save a visualization, expand the **Save** dropdown menu in the upper-right corner, enter a name for the visualization, and then select the **Save** button. You can reopen saved visualizations on the event analytics page.

 ## Creating event analytics visualizations and adding them to dashboards
 
-This feature is available in OpenSearch Dashboards version 2.7 and later. It works with new visualizations created in version 2.7 or later that use PPL to query data from OpenSearch or federated data sources such as Prometheus.

 ### Limitations of event analytics visualizations

 ### Correlating logs and traces
 
-If you regularly track events across applications, you can correlate logs and traces. To view the correlation, you have to index the traces according to Open Telemetry standards (similar to trace analytics). Once you add a `TraceId` field to your logs, you can view the correlated trace information in the event explorer log details. This method lets you correlate logs and traces that correspond to the same execution context.

 ### Livestreaming logs
 
-If you prefer watching events happen live, you can configure an interval so event analytics automatically refreshes the content. Live tail lets you stream logs live to OpenSearch observability event analytics based on the provided PPL query, as well as provide rich functionality such as filters. Doing so improves your debugging experience and lets you monitor your logs in real-time without having to manually refresh.
+If you prefer real-time monitoring, you can set up an interval at which event analytics content will be automatically refreshed. With Live Tail, you can stream logs directly to OpenSearch Observability event analytics using the specified PPL query while leveraging robust features like filters. This can enhance your debugging process and enables seamless real-time monitoring of logs without the need to manually refresh content.
 
-You can also choose intervals and switch between them to dictate how often live tail should stream live logs. This feature is similar to the CLI's `tail -f` command in that it only retrieves the most recent live logs by possibly eliminating a large portion of live logs. Live tail also provides you with the total count of live logs received by OpenSearch during the live stream, which you can use to better understand the incoming traffic.
