Osquery module

The osquery module collects and decodes the result logs written by osqueryd in the JSON format. To set up osqueryd follow the osquery installation instructions for your operating system and configure the filesystem logging driver (the default). Make sure UTC timestamps are enabled.

When you run the module, it performs a few tasks under the hood:

• Sets the default paths to the log files (but don’t worry, you can override the defaults)
• Makes sure each multiline log event gets sent as a single event
• Uses an Elasticsearch ingest pipeline to parse and process the log lines, shaping the data into a structure suitable for visualizing in Kibana
• Deploys dashboards for visualizing the log data

The osquery module was tested with logs from osquery version 2.10.2. Since the results are written in the JSON format, it is likely that this module works with any version of osquery.

This module is available on Linux, macOS, and Windows.

You can further refine the behavior of the osquery module by specifying variable settings in the modules.d/osquery.yml file, or overriding settings at the command line.

You must enable at least one fileset in the module. Filesets are disabled by default.

The following example shows how to set paths in the modules.d/osquery.yml file to override the default paths for the syslog and authorization logs:

- module: osquery
  result:
    enabled: true
    var.paths: ["/path/to/osqueryd.results.log*"]

To specify the same settings at the command line, you use:

-M "osquery.result.var.paths=[/path/to/osqueryd.results.log*]"

Each fileset has separate variable settings for configuring the behavior of the module. If you don’t specify variable settings, the osquery module uses the defaults.

For advanced use cases, you can also override input settings. See Override input settings.

var.paths

An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.

var.use_namespace

If true, all fields exported by this module are prefixed with osquery.result. Set to false to copy the fields in the root of the document. If enabled, this setting also disables the renaming of some fields (e.g. hostIdentifier to host_identifier). Note that if you set this to false, the sample dashboards coming with this module won’t work correctly. The default is true.

This module comes with a sample dashboard for visualizing the data collected by the "compliance" pack. To collect this data, enable the it-compliance pack in the osquery configuration file.

For a description of each field in the module, see the exported fields section.
