+
+Query log analyzer is a feature that provides a UI to review the queries executed on an Aura instance.
+
+To access *Query log analyzer*:
+
+. Navigate to the https://console.neo4j.io/?product=aura-db[Neo4j Aura Console] in your browser.
+. Select the instance you want to access.
+. Select the *Logs* tab.
+. Select the *Query log analyzer* button.
+
+Query log analyzer is split up in two parts, a timeline and a table with two tabs:
+
+* *Query timeline* - Timeline showing metrics for number of queries, failed queries and query latency.
+* *Summary* - An aggregated view of query logs, giving a high level overview over the selected time period.
+* *Details* - A detailed view showing individual query executions in the selected time period. 
+
+To fetch logs, first choose a time range in the Query timeline. 
+With a time selection done, press the *Fetch logs* button. 
+You may optionally choose any filters or search text if required, then press *Go*.
+
+A summary of query executions is returned, showing aggregations per query.
+To see the individual query executions, click the right arrow at the end of the line to show details for that query.
+The details pane shows individual executions.
+
+== Chart interactions
+
+When viewing the query timeline, you can select from the following time intervals:
+
+* 30 minutes
+* Last hour
+* Last 2 hours
+* Last 6 hours
+* Last 24 hours
+* Last 3 days
+* Last week
+
+=== Zoom
+
+To zoom in to a narrower time interval, select and drag inside the timeline to select your desired time interval.
+The data in the timeline will automatically update to match the increased resolution.
+To update the table, click the *Fetch logs* button.
+
+To reset zoom, double-click anywhere inside the timeline.
+
+=== Toggle data series
+
+To hide or show individual data series, select the corresponding data series in the legend below the timeline.
+
+== Table interactions
+
+=== Sort table
+
+By default the table will be sorted on *Count* for *Summary* and *Status* for *Details*.
+To sort by a column (such as Max Time ms) click on the column heading.
+
+=== Modify columns
+
+The columns in the table can be modified by clicking the button to the right of the column row.
+Columns can be enabled or disabled, or the order changed using the grid icon at the top right of the table.
+
+=== Expand query
+
+In the table three rows of query text will be shown. 
+To see the whole query if the query is longer, press the *View more* button under the query text.
+
+== Limitations
+
+Query logs are available for a period of 7 days, and each request can be for up to 24 hours of data.
