Log Search
Effective Log Search & Analytics provides a separate Web App screen for searching logs.
Access Web App
1. In the NAVER Cloud Platform console, click Menu > 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.

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.
① You can define search criteria using Lucene Syntax 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.
- 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.

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.
