Analyze data using Log Analytics Simple mode (Preview)

Log Analytics now offers two modes that make log data simpler to explore and analyze for both basic and advanced users:

  • Simple mode provides the most commonly used Azure Monitor Logs functionality in an intuitive, spreadsheet-like experience. Just point and click to filter, sort, and aggregate data to get to the insights you need 80% of the time.
  • KQL mode gives advanced users the full power of Kusto Query Language (KQL) to derive deeper insights from their logs using the Log Analytics query editor.

You can switch seamlessly between Simple and KQL modes, and advanced users can share complex queries that anyone can continue working with in Simple mode.

This article explains how to use Log Analytics Simple mode to explore and analyze data in Azure Monitor Logs.

Here's a video that provides a quick overview of how to query logs in Log Analytics using both Simple and KQL modes:

Try Log Analytics Simple mode

Simple mode is currently an opt-in experience. To try it, select Try the new Log Analytics at the top right corner of the Log Analytics query editor. You can switch back to the classic Log Analytics experience at any time.

How Simple mode works

Simple mode lets you get started quickly by retrieving data from one or more tables with one click. You then use a set of intuitive controls to explore and analyze the retrieved data.

This section orients you with the controls available in Log Analytics Simple mode.

Get started in Simple mode

When you select a table or a predefined query or function in Simple mode, Log Analytics automatically retrieves the relevant data for you to explore and analyze.

This lets you retrieve logs with one click whether you open Log Analytics in resource or workspace context.

To get started, you can:

  • Click Select a table and select a table from the Tables tab to view table data.

    Screenshot that shows the Select a table button in Log Analytics.

    Alternatively, select Tables from the left pane to view the list of tables in the workspace.

    Screenshot that shows the Tables tab in Log Analytics.

  • Use an existing query, such as a shared or saved query, or an example query.

    Screenshot that shows an example query in Log Analytics.

  • Select a query from your query history.

  • Select a function.

    Functions let you reuse query logic and often require input parameters or additional context. In such cases, the function won't run until you switch to KQL mode and provide the required input.

Explore and analyze data in Simple mode

After you get started in Simple mode, you can explore and analyze data using the top query bar.


The order in which you apply filters and operators affects your query and results. For example, if you apply a filter and then aggregate, Log Analytics applies the aggregation to the filtered data. If you aggregate and then filter, the aggregation is applied to the unfiltered data.

Change time range and number of records displayed

By default, Simple mode lists the latest 1,000 entries in the table from the last 24 hours.

To change the time range and number of records displayed, use the Time range and Limit selectors. For more information about result limit, see Configure query result limit

Screenshot that shows the time range and limit selectors in Log Analytics.

Filter by column

  1. Select Add and choose a column.

    Screenshot that shows the Add filters menu that opens when you select Add in Log Analytics Simple mode.

  2. Select a value to filter by, or enter text or numbers in the Search box.

    If you filter by selecting values from a list, you can select multiple values. If the list is long, you'll see a Not all results are shown message. Scroll to the bottom of the list and select Load more results to retrieve more values.

Search for entries that have a specific value in the table

  1. Select Search.

    Screenshot that shows the Search option in Log Analytics Simple mode.

  2. Enter a string in the Search this table box and select Apply.

    Log Analytics filters the table to show only entries that contain the string you entered.


We recommend using Filter if you know which column holds the data you're searching for. The search operator is substantially less performant than filtering, and might not function well on large volumes of data.

Aggregate data

  1. Select Aggregate.

  2. Select a column to aggregate by and select an operator to aggregate by, as described in Use aggregation operators.

    Screenshot that shows the aggregation operators in the Aggregate table window in Log Analytics.

Show or hide columns

  1. Select Show columns.

  2. Select or clear columns to show or hide them, then select Apply.

    Screenshot that shows the Show columns window in Log Analytics.

Sort by column

  1. Select Sort.

  2. Select a column to sort by.

  3. Select Ascending or Descending, then select Apply.

    Screenshot that shows the Sort by column window in Log Analytics.

  4. Select Sort again to sort by another column.

Use aggregation operators

Use aggregation operators to summarize data from multiple rows, as described in this table.

Operator Description
count Counts the number of times each distinct value exists in the column.
dcount For the dcount operator, you select two columns. The operator counts the total number of distinct values in the second column correlated to each value in the first column. For example, this shows the distinct number of result codes for successful and failed operations:
Screenshot that shows the result of an aggregation using the dcount operator in Azure Monitor Log Analytics.
For these operators, you select two columns. The operators calculate the sum, average, maximum, or minimum of all values in the second column for each value in the first column. For example, this shows the total duration of each operation in milliseconds for the past 24 hours:

Basic logs tables don't support aggregation using the avg and sum operators.

Switch modes

To switch modes, select Simple mode or KQL mode from the dropdown in the top right corner of the query editor.

Screenshot that shows how to toggle between Simple mode and KQL mode in Log Analytics.

When you begin to query logs in Simple mode and then switch to KQL mode, the query editor is prepopulated with the KQL query related to your Simple mode analysis. You can then edit and continue working with the query.

For straightforward queries on a single table, Log Analytics displays the table name at the right of the top query bar in Simple mode. For more complex queries, Log Analytics displays User Query at the left of the top query bar. Select User Query to return to the query editor and modify your query at any time.

Screenshot that shows the User Query button, which lets you return to the query editor when you're in Simple mode.

Configure query result limit

  1. Select Limit to open the Limit results window.

    Screenshot that shows the limit results window in Log Analytics.

  2. Select one of the preset limits, or enter a custom limit.

    The maximum number of results that you can retrieve in the Log Analytics portal experience, in both Simple mode and KQL mode, is 30,000. However, when you share a Log Analytics query with an integrated tool, or use the query in a search job, the query limit is set based on the tools you choose.

    Select Max. limit to return the maximum number of results provided by any of the tools available on the Share window or using a search job.

    Screenshot that shows the Share window in Log Analytics.

    This table lists the maximum result limits of Azure Monitor log queries using the various tools:

    Tool Description Max. limit
    Log Analytics Queries you run in the Azure portal. 30,000
    Excel, Power BI, Log Analytics Query API Queries you use in Excel and Power BI, which are integrated with Log Analytics, and queries you run using the API. 500,000
    Search job Azure Monitor reingests the results of a query your run in search job mode into a new table in your Log Analytics. 1,000,000
