Osquery moduleedit

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 ingest node 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

Compatibilityedit

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.

Example dashboardedit

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

Configure the moduleedit

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.

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*]"

Variable settingsedit

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 more information, see Specify variable settings. Also see Advanced settings.

Tip

When you specify a setting at the command line, remember to prefix the

result fileset settingsedit

var.paths
An array of paths that specify where to look for the log files. If left empty, Filebeat will choose the paths depending on your operating systems.
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.
