Installing the PCI Compliance for Linux App

Now that you have set up collection, install the Sumo Logic App for PCI Compliance for Linux to use the preconfigured searches and dashboards that provide insight into your data.

To install the app:

1. From the left nav, select App Catalog.
   
2. Search for your app name and select it.
3. When you get to your app page:
   • If you want to see a preview of the dashboards included with the app before installing, scroll down to Dashboard Preview.
   • If your Sumo Logic app has multiple versions (not all apps do), select the version of the service you're using.
     
   • Click Add Integration.
     
4. On the next configuration page, Select Data Source for your App, complete the following fields:
   • Data Source. Select one of the following options:
     • Choose Source Category, and select a source category from the list; or
     • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. For example, _sourceCategory=MyCategory.
   • Folder Name. You can retain the existing name or enter a custom name of your choice for the app.
   • All Folders (optional). Default location is the Personal folder in your Library. If desired, you can choose a different location and/or click New Folder to add it to a new folder.
5. Click Next.
   
6. You'll see a dialog confirming that the app was installed successfully.
   

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 be available immediately, but within 20 minutes, you'll see full graphs and maps.
