Collection configuration and app installation

Depending on the set up collection method, you can configure and install the app in three ways:

Create a new collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under a new Sumo Logic Collector and later install the app; Or
Use an existing collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under an existing Sumo Logic Collector and later install the app; Or
Use existing source and install the app. Use your existing configured Sumo Logic Cloud-to-Cloud (C2C) source and install the app.

info

Use the Cloud-to-Cloud Integration for CrowdStrike FDR Host Inventory to create the source and use the same source category while installing the app. By following these steps, you can ensure that your CrowdStrike FDR Host Inventory app is properly integrated and configured to collect and analyze your CrowdStrike FDR Host Inventory data.

Create a new collector and install the app

To set up collection and install the app, do the following:

Select App Catalog.
In the 🔎 Search Apps field, run a search for your desired app, then select it.
Click Install App.
note
Sometimes this button says Add Integration.
In the Set Up Collection section of your respective app, select Create a new Collector.
1. Collector Name. Enter a Name to display for the Source in the Sumo Logic web application. The description is optional.
2. Timezone. Set the default time zone when it is not extracted from the log timestamp. Time zone settings on Sources override a Collector time zone setting.
3. (Optional) Metadata. Click the +Add Metadata link to add custom log Metadata Fields. Define the fields you want to associate, each metadata field needs a name (key) and value.
  - A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
  - An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
4. Click Next.
Use the new Cloud-to-Cloud Integration to configure the source.
In the Configure section of your respective app, complete the following fields.
1. Key. Select either of these options for the data source.
  - Choose Source Category and select a source category from the list for Default Value.
  - Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, but will update with full graphs and charts over time.

Use an existing collector and install the app

To setup source in the existing collector and install the app, do the following:

Select App Catalog.
In the 🔎 Search Apps field, run a search for your desired app, then select it.
Click Install App.
note
Sometimes this button says Add Integration.
In the Set Up Collection section of your respective app, select Use an existing Collector.
From the Select Collector dropdown, select the collector that you want to setup your source with and click Next.
Use the new Cloud-to-Cloud Integration to configure the source.
In the Configure section of your respective app, complete the following fields.
1. Key. Select either of these options for the data source.
  - Choose Source Category and select a source category from the list for Default Value.
  - Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Use an existing source and install the app

To skip collection and only install the app, do the following:

Select App Catalog.
In the 🔎 Search Apps field, run a search for your desired app, then select it.
Click Install App.
note
Sometimes this button says Add Integration.
In the Set Up Collection section of your respective app, select Skip this step and use existing source and click Next.
In the Configure section of your respective app, complete the following fields.
1. Key. Select either of these options for the data source.
  - Choose Source Category and select a source category from the list for Default Value.
  - Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Viewing CrowdStrike FDR Host Inventory dashboards

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.

Overview

The CrowdStrike - FDR Host Inventory Overview dashboard offers a comprehensive view of the devices monitored by CrowdStrike Falcon Data Replicator (FDR) to enhance the environment’s security posture. It provides key insights into the total number of devices categorized by platform, status, and manufacturer. This dashboard also highlights the geographical distribution of devices and risky devices. Additionally, it provides critical information on device operating systems, latest-seen devices, software details, network configurations, and policy details.
