Juniper module

edit

This is a module for ingesting data from the different Juniper Products. Currently supports these filesets:

  • srx fileset: Supports Juniper SRX logs

Read the quick start to learn how to configure and run modules.

Configure the module

edit

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

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

Variable settings

edit

Each fileset has separate variable settings for configuring the behavior of the module. If you don’t specify variable settings, the juniper 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, juniper.{fileset_ex}.var.paths instead of {fileset_ex}.var.paths.

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

srx fileset settings

The Juniper-SRX module only supports syslog messages in the format "structured-data + brief" JunOS Documentation structured-data

Compatibility

edit

This module has been tested against JunOS version 19.x and 20.x. Versions above this are expected to work but have not been tested.

- module: juniper
  junos:
    enabled: true
    var.input: udp
    var.syslog_host: 0.0.0.0
    var.syslog_port: 9006
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.input
The input to use, can be either the value tcp, udp or file.
var.syslog_host
The interface to listen to all syslog traffic. Defaults to localhost. Set to 0.0.0.0 to bind to all available interfaces.
var.syslog_port
The port to listen for syslog traffic. Defaults to 9006.
