Juniper moduleedit

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

  • srx fileset: Supports Juniper SRX logs
  • junos fileset: Supports Juniper JUNOS logs
  • netscreen fileset: Supports Juniper Netscreen logs

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

Configure the moduleedit

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.

Variable settingsedit

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 settingsedit

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

To configure a remote syslog destination, please reference the SRX Getting Started - Configure System Logging.

The following processes and tags are supported:

JunOS processes JunOS tags

RT_FLOW_SESSION_CREATE

RT_FLOW_SESSION_CLOSE

RT_FLOW_SESSION_DENY

The syslog format choosen should be Default.

Compatibilityedit

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: sophosxg
  firewall:
    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.

junos fileset settingsedit

This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features.

This was converted from RSA NetWitness log parser XML "junosrouter" device revision 134.

var.input
The input from which messages are read. One of file, tcp or udp.
var.syslog_host
The address to listen to UDP or TCP based 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 9513

Ports below 1024 require Filebeat to run as root.

var.tz_offset
By default, datetimes in the logs will be interpreted as relative to the timezone configured in the host where Filebeat is running. If ingesting logs from a host on a different timezone, use this field to set the timezone offset so that datetimes are correctly parsed. Valid values are in the form ±HH:mm, for example, -07:00 for UTC-7.
var.rsa_fields
Flag to control the addition of non-ECS fields to the event. Defaults to true, which causes both ECS and custom fields under rsa to be added.
var.keep_raw_fields
Flag to control the addition of the raw parser fields to the event. This fields will be found under rsa.raw. The default is false.
