# Juniper JUNOS module
<admonition title="Prefer to use Elastic Agent for this use case?">
  Refer to the [Elastic Integrations documentation](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2341/reference).
  <dropdown title="Learn more">
    Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to the documentation for a detailed [comparison of Beats and Elastic Agent](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2341/reference/fleet).

This is a module for ingesting data from the different Juniper Products. Currently supports these filesets:
- `srx` fileset: Supports Juniper SRX logs

<tip>
  Read the [quick start](https://www.elastic.co/elastic/docs-builder/docs/2341/reference/beats/filebeat/filebeat-installation-configuration) to learn how to configure and run modules.
</tip>


## Configure the module

You can further refine the behavior of the `juniper` module by specifying [variable settings](#juniper-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

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](https://www.elastic.co/elastic/docs-builder/docs/2341/reference/beats/filebeat/advanced-settings).
<tip>
  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`.
</tip>

<warning>
  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.
</warning>


### `srx` fileset settings

The Juniper-SRX module only supports syslog messages in the format "structured-data + brief" [JunOS Documentation structured-data](https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/structured-data-edit-system.html)
To configure a remote syslog destination, please reference the [SRX Getting Started - Configure System Logging](https://kb.juniper.net/InfoCenter/index?page=content&id=kb16502).
The following processes and tags are supported:

| JunOS processes | JunOS tags                   |
|-----------------|------------------------------|
| RT_FLOW         | RT_FLOW_SESSION_CREATE       |

| RT_SECINTEL     | SECINTEL_ACTION_LOG          |

The syslog format choosen should be `Default`.

## Compatibility

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.
```yaml
- module: juniper
  junos:
    enabled: true
    var.input: udp
    var.syslog_host: 0.0.0.0
    var.syslog_port: 9006
```

<definitions>
  <definition term="var.paths">
    An array of glob-based paths that specify where to look for the log files. All patterns supported by [Go Glob](https://golang.org/pkg/path/filepath/#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.
  </definition>
  <definition term="var.input">
    The input to use, can be either the value `tcp`, `udp` or `file`.
  </definition>
  <definition term="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.
  </definition>
  <definition term="var.syslog_port">
    The port to listen for syslog traffic. Defaults to 9006.
  </definition>
</definitions>
