Sumo Logic App for Windows JSON

The Windows JSON App provides insight into your Windows system's operation and events so that you can better manage and maintain your environment. The Windows JSON App is based on the JSON Windows event log format and consists of predefined searches and dashboards that provide visibility into your environment for real-time analysis of overall usage of Security Status, System Activity, Updates, User Activity, and Applications.

Log Types

The Windows JSON App assumes events are coming from Windows Event Log Sources in JSON format. It does not work with third party logs.

Standard Windows event channels include:

• Security
• System
• Application

Custom event channels, such as PowerShell or Internet Explorer are also supported.

Sample Query

The sample query is from the Recent Policy Changes panel from Windows - Overview dashboard.

_sourceCategory=Labs/windows-jsonformat ( "Audit Policy Change" or "System audit policy was changed" or *policy*change* or "Policy Change" or 4902 or 4904 or 4905 or 4906 or 4907 or 4912 or 4715 or 4719 or 4739)

Collecting Logs for the Windows JSON App

This section provides instructions on configuring log collection for the Windows JSON App so that logs are collected from the Microsoft Windows Event Log and ingested into Sumo Logic.

Configure a Collector and Source

To configure a collector and source, do the following:

1. Configure an Installed Windows collector through the user interface or from the command line.
2. Configure either a local or remote Windows Event Log source. To configure a Windows Event Log source set the following:

• Event Format. Select Collect using JSON format. Events are formatted into JSON that is designed to work with Sumo Logic features, making it easier for you to reference your data.
  
• Event Collection Level. When JSON format is selected you have to select Complete Message from the dropdown. Complete Message will ingest the entire event content, along with metadata.
  

For more information on local or remote Windows Event Log Source configuration, refer to Local Windows Event Log Source and Remote Windows Event Log Source.

Installing the Windows JSON App

This section has instructions for installing the Sumo Logic JSON App for Windows and descriptions of each of the app dashboards.

To install the app:

Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.

1. From the App Catalog, search for and select the app.
2. Select the version of the service you're using and click Add to Library. Version selection is applicable only to a few apps currently. For more information, see the Install the Apps from the Library.
3. To install the app, complete the following fields.
   • App Name. You can retain the existing name, or enter a name of your choice for the app.

   • Data Source. Select either of these options for the data source.

     • Choose Source Category, and select a source category from the list.

     • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (_sourceCategory=MyCategory).

   • Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
4. Click Add to Library.

Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization.

Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps.

Viewing Windows JSON Dashboards

Filter with template variables

Template variables provide dynamic dashboards that can rescope data on the fly. As you apply variables to troubleshoot through your dashboard, you view dynamic changes to the data for a quicker resolution to the root cause. You can use template variables to drill down and examine the data on a granular level. For more information, see Filter with template variables.
