In the NAVER Cloud Platform console, click **Menu** > **All Services** > **Management & Governance** > **Effective Log Search & Analytics** menu in order. 2. Select the **Projects** menu, then in the list of projects, click the **[Go to Web-APP]** button for the project whose logs you want to view. 3. A new window displays the Effective Log Search & Analytics Web App. ### How to search logs: By default, the **Search** menu in the Effective Log Search & Analytics Web App displays logs for the last 24 hours as of the current time in the form of a graph of log collection counts by time zone and a detailed log. ![elsa_webapp_search_1-1_ko.png](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/elsa_webapp_search_1-1_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A18Z&se=2026-11-14T06%3A05%3A18Z&sr=c&sp=r&sig=CxdXTDKoY%2FL%2Ff7iWxL%2BtmgV20V8jz4ROZmDUb3hOb%2BE%3D) ① You can define search criteria using [Lucene Syntax](http://lucene.apache.org/core/old_versioned_docs/versions/2_9_1/queryparsersyntax.html) in the query field. ② You can set the search time range and view logs collected during the specified period. ③ The log search results are displayed as a bar graph. The number of logs collected between the timestamps on the horizontal axis is displayed. You can click a bar to view only the logs for that period, or double-click the bar to view more detailed logs by time. ④ Effective Log Search & Analytics makes it easy to filter logs using **quick filters**. - Quick filters appear in the filter items only when there is at least one log in the search results that has data for each item. - Example: If there are only logs with logLevel, logSource, and projectVersion values and no logs with logType values in the current search results, logType will not appear in the quick filter items. ⑤ This is where the details of the searched logs are displayed. **You can click each entry in the output log to enter it into the query in ①.** ## Visualize logs Effective Log Search & Analytics provides the ability to visualize logs to construct dashboards. Effective Log Search & Analytics has Kibana built-in, which allows you to query the log data you want and construct dashboards. ### Discover You can write queries through the **Kibana > Discover** menu to retrieve Log Data to visualize. Queries built through the Discover menu can be saved and loaded as a range of Data to be included in the individual Widgets that make up the dashboard when creating a dashboard. ![elsa_webapp_kibana_discover_1_ko.png](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/elsa_webapp_kibana_discover_1_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A18Z&se=2026-11-14T06%3A05%3A18Z&sr=c&sp=r&sig=CxdXTDKoY%2FL%2Ff7iWxL%2BtmgV20V8jz4ROZmDUb3hOb%2BE%3D) - You can write a Lucene Query to retrieve the collected log data. After entering a Lucene Query and selecting the period, click the **[Refresh]** button to view the histogram and detailed Log Data retrieved by the query. ![elsa_webapp_kibana_discover_2_ko.png](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/elsa_webapp_kibana_discover_2_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A18Z&se=2026-11-14T06%3A05%3A18Z&sr=c&sp=r&sig=CxdXTDKoY%2FL%2Ff7iWxL%2BtmgV20V8jz4ROZmDUb3hOb%2BE%3D) - The Discover menu also allows you to view the discovered log data in a table format. When you select a field to add to the table from the left side menu, log data is displayed in a tabular format, with the selected fields displayed as columns in the table. - After checking the log data, you can save the currently set conditions by clicking the **[Save]** button at the top. Saved queries can be viewed via the **Kibana > Query list** menu, and can be used as a data source when adding new widgets from the **Dashboards > Create Visualization** menu. - Click the **[Inspect]** button to see a summary of the current search results, as well as requested and received information. ### Query list You can see a list of the queries you have saved from the Discover menu via the **Kibana > Query list** menu. ![elsa_webapp_kibana_query_ko.png](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/elsa_webapp_kibana_query_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A18Z&se=2026-11-14T06%3A05%3A18Z&sr=c&sp=r&sig=CxdXTDKoY%2FL%2Ff7iWxL%2BtmgV20V8jz4ROZmDUb3hOb%2BE%3D) - In the **Query List** menu, you can view a list of queries that you have saved from the **Discover** menu, and delete or edit them. - You can create a new query by clicking the **[Add Search]** button, and you can use the created query as a data source when adding a new Widget from the **Dashboards > Create Visualization** menu. ### Create a visualization You can visualize Log Data by selecting it through the **Dashboards > Create Visualization** menu. ![elsa_webapp_dashboard_createvisualize_1_ko.png](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/elsa_webapp_dashboard_createvisualize_1_en.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A05%3A18Z&se=2026-11-14T06%3A05%3A18Z&sr=c&sp=r&sig=CxdXTDKoY%2FL%2Ff7iWxL%2BtmgV20V8jz4ROZmDUb3hOb%2BE%3D) - It supports a variety of visualization methods, including Area/Line Chart, Heat Map, and more. - After you choose how you want to visualize, you can select the data source.
