Falcon LogScale data source for Grafana

The CrowdStrike Falcon LogScale data source plugin allows you to query and visualize Falcon LogScale data from within Grafana.

Install the plugin

To install the data source, refer to Installation.

Configure the data source in Grafana

Add a data source by filling in the following fields:

Basic fields

Authentication fields

Custom HTTP Header Data sources managed by provisioning within Grafana can be configured to add HTTP headers to all requests going to that data source. The header name is configured in the jsonData field, and the header value should be configured in secureJsonData. For more information about custom HTTP headers, refer to Custom HTTP Headers.

LogScale Token Authentication

You can authenticate using your personal LogScale token. To generate a personal access token, log into LogScale and navigate to User Menu > Manage Account > Personal API Token. Then, set or reset your token. Copy and paste the token into the token field.

Forward OAuth Identity

Note: The feature is experimental, which means it may not work as expected, it may cause Grafana to behave in an unexpected way, and breaking changes may be introduced in the future.

Prerequisites

OAuth identity forwarding is only possible with a self-hosted LogScale instance appropriately configured with the same OAuth provider as Grafana. Not all OAuth/OIDC configurations may be supported currently.

With this authentication method enabled, a token will not need to be provided to make use of a LogScale data source. Instead, users that are logged in to Grafana with the same OAuth provider as the LogScale instance will have their token forwarded to the data source and that will be used to authenticate any requests.

Note: Some Grafana features will not function as expected e.g. alerting. Grafana backend features require credentials to always be in scope which will not be the case with this authentication method.

Default LogScale Repository

You can set a default LogScale repository to use for your queries. If you do not specify a default repository, you must select a repository for each query.

Configure data links

Data links allow you to link to other data sources from your Grafana panels. For more information about data links, refer to Data links.

To configure a data link, click the add button in the data links section of the data source configuration page. Fill out the fields as follows:

Configure the data source with provisioning

It is possible to configure data sources using configuration files with Grafana’s provisioning system. To read about how it works, including all the settings that you can set for this data source, refer to Provisioning Grafana data sources

Here are some provisioning examples for this data source using basic authentication:

apiVersion: 1
datasources:
  - name: Falcon LogScale
    type: grafana-falconlogscale-datasource
    url: https://cloud.us.humio.com
    jsonData:
      defaultRepository: <defaultRepository or blank>
      authenticateWithToken: true
    secureJsonData:
      accessToken: <accessToken>

Query the data source

The query editor allows you to write LogScale Query Language (LQL) queries. For more information about writing LQL queries, refer to Query Language Syntax. Select a repository from the drop-down menu to query. You will only see repositories that your data source account has access to.

Selecting $defaultRepo from the Repository dropdown automatically maps to the default repository configured for the datasource which enables switching between multiple LogScale datasources.

You can use your LogScale saved queries in Grafana. For more information about saved queries, refer to User Functions.

Here are some useful LQL functions to get you started with Grafana visualizations:

Explore view

The Explore view allows you to run LQL queries and visualize the results as logs or charts. For more information about Explore, refer to Explore. For more information about Logs in Explore, refer to Explore logs.

Grafana v9.4.8 and later allows you to create data links in Tempo, Grafana Enterprise Traces, Jaeger, and Zipkin that target Falcon LogScale.

Templates and variables

To add a new Falcon LogScale query variable, refer to Add a query variable. Use your Falcon LogScale data source as your data source. Fill out the query field with your LQL query and select a Repository from the drop-down menu. The template variable will be populated with the first column from the results of your LQL query.

After creating a variable, you can use it in your Falcon LogScale queries using Variable syntax. For more information about variables, refer to Templates and variables.

Import a dashboard for Falcon LogScale

Follow these instructions for importing a dashboard.

You can find imported dashboards in Configuration > Data Sources > select your Falcon LogScale data source > select the Dashboards tab to see available pre-made dashboards.
