View analysis history

Analysis history tracks which spatial analysis tools have been run in a web map, including successful and unsuccessful runs. You can view detailed information about each tool that was run and reopen the tool with the same settings you previously used. You can use analysis history to troubleshoot errors with analysis tools, reopen tools with the settings used in a previous run, and document or share your analysis workflow. The analysis history is visible to users who view a shared web map.

When you run an analysis tool in a web map, an entry is added in the Analysis pane under History.

History entries

Each history entry maintains detailed information about the tool run, including the following:

• The tool input, output, and other parameter settings.
• Any environment settings.
• When the tool was run, when the tool finished running, and how long it took to run.
• The amount of credits consumed.
• Whether the tool completed successfully or failed.

  Note:

  The status of a tool run is saved when you save a web map. If you last saved a web map and the tool is still running, you won't see an updated status the next time you open the map.

• Any information, warning, or error messages.
• Links to created items.

Cancel the analysis

For tools that are still running, you can choose to cancel the analysis.

1. On the Settings (light) toolbar, click Analysis .
2. Click History .
3. Click Cancel .

   A dialog box appears asking you to confirm the cancellation.

4. If you are sure you want to cancel, click Cancel analysis. To continue with the analysis, click Keep running.

Not all tools can be canceled. Tools that cannot be canceled will have an information icon instead of a cancel button.

Manage history

If you open a saved web map at a later time to continue your work, the analysis tools that you previously ran in the project will be available in your analysis history. You can complete the following operations on any analysis history item:

• View details—Shows the messages, inputs and outputs, tool parameters, tool run time, and credits.
• Reopen a tool pane—Reopens the tool with populated tool parameters.
• Remove a tool run from history—Deletes the tool run from the history. This does not delete the resulting layers.

View analysis details

The analysis details store information about each tool run, including the result layer created from a successful run, messages that can be used to troubleshoot errors, and a summary of the tool parameters.

1. On the Settings (light) toolbar, click Analysis .
2. Click History .

   All successful and unsuccessful tool runs from the web map are listed. You can learn more about an individual tool run.

3. Click Options.
4. Click View details.

   For successful tool runs, the analysis details open on the Results tab. For tool runs that failed or were canceled, the analysis details open on the Messages tab.

5. Click the Results tab.

   The Results tab displays the result layer from the selected tool run. You can optionally use the Results tab to zoom to the result layer or open the result table, add the layer or table to the map, or open the item details page.

6. Click the Messages tab.

   The Messages tab provides information on when the tool was run, the run time, and the number of credits consumed for successful runs, and error messages for unsuccessful runs.

7. Click the Parameters tab.

   The Parameters tab provides a summary of the configurations used to run the tool.

Some input parameter values may not appear exactly as they appear in the tool pane. The following are examples:

• If you use a processing extent from another layer, you will not see the layer URL. Instead you will see the extent values for the layer that was specified.
• If you use a processing extent derived from the display extent, you will see the extent values from the display extent at the time the tool was run.
• If you use an output spatial reference from another layer, you will not see the layer URL. Instead you will see the spatial reference for the layer that was specified.
• Some parameters may show a JSON or list representation of the input values.

Reopen tool runs

Complete the following steps to reopen a tool run:

1. On the Settings (light) toolbar, click Analysis .
2. Click History .
3. Click Options.
4. Click Open tool.

The tool pane appears with the configurations used when the tool was run.

Note:

You must provide a new output name to rerun the tool.

If you open a tool that had a filter applied to an input layer, the filter will not be honored when you rerun the tool. Tools only honor the filter that is currently applied to the layer in the map.

If a map has been shared with you and you don't have the privileges or license required to rerun a tool, you won't be able to reopen the tool. Similarly, some tools have parameters that require specific privileges or licenses to run them. You can reopen these tools, but the parameter will be set to a value that you have privileges for.

Remove tool runs

Complete the following steps to remove a tool run from the analysis history:

1. On the Settings (light) toolbar, click Analysis .
2. Click History .
3. Click Options.
4. Click Remove.

The tool is removed from the analysis history.

Save your history

History is saved when you save a web map. History is only saved for tools run in Map Viewer, and cannot be opened in Map Viewer Classic. Similarly, tools run in Map Viewer Classic will not be saved in history. To reopen any tool runs completed in Map Viewer Classic, use the rerun option in Map Viewer Classic.

If you save your map while a tool is running, the status for that tool run will be saved as in progress. To avoid having erroneous states, save your map once the tool run has completed.

Share your analysis

When you save a web map, the history is saved with it. When you share a web map with history, users can view details of the history and reopen parameters.

If you share a web map with everyone, the history can be viewed by users outside of your organization. However, copying analysis history between organizations is not supported. For example, if a user outside of your organization chooses to save your web map as a new item, analysis history will not be available in their new map.

If you don't have the privileges or license required to run a tool, you won't be able to reopen the tool.

Some tools have parameters that require specific privileges or licenses to run them. You can reopen these tools, but the parameter will be set to a value that you have privileges for.
