Auditd module
editAuditd module
editThe auditd
module collects and parses logs from the audit daemon
(auditd
).
Although Filebeat is able to parse logs by using the auditd
module,
Auditbeat offers more advanced
features for monitoring audit logs.
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

Compatibility
editThe auditd
module was tested with logs from auditd
on OSes like CentOS
6 and CentOS 7.
This module is not available for Windows.
Configure the module
editYou can further refine the behavior of the auditd
module by specifying
variable settings in the
modules.d/auditd.yml
file, or overriding settings at the command line.
The following example shows how to set paths in the modules.d/auditd.yml
file to override the default paths for logs:
- module: auditd log: enabled: true var.paths: ["/path/to/log/audit/audit.log*"]
To specify the same settings at the command line, you use:
-M "auditd.log.var.paths=[/path/to/log/audit/audit.log*]"
Variable settings
editEach fileset has separate variable settings for configuring the behavior of the
module. If you don’t specify variable settings, the auditd
module uses
the defaults.
For advanced use cases, you can also override input settings. See Override input settings.
When you specify a setting at the command line, remember to prefix the
setting with the module name, for example, auditd.log.var.paths
instead of log.var.paths
.
log
fileset settings
edit-
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.
Example dashboard
editThis module comes with a sample dashboard showing an overview of the audit log data. You can build more specific dashboards that are tailored to the audit rules that you use on your systems.
