Send Your Logs to Loggly

Loggly supports any text-based log data. The most common way to send system and application logs to Loggly is using a local syslog agent. Below are the instructions to send system and application logs using a local syslog agent. For other methods of sending log data to Loggly, see Logging Setup.

Sending Logs from a Linux Syslog Agent

The following script run in just a few seconds and will perform several system compatibility checks, configure rsyslog using best practices, and verify the logs reach to our system. It assumes you have sudo access, you’re on a common linux distribution with rsyslog 5.8 or higher, it receives local system logs, and port 514 (insecure logging port) 6514 (secure logging port) is open to outbound connections. For more detailed information about this script, to configure rsyslog for other logging scenarios, or for rsyslog troubleshooting tips, see Syslog Configuration Scripts.

Configure-linux script

This script sends the system logs to Loggly. The script by default send the logs securely but if package manager (rsyslog-gnutls) could not be installed in your distribution then it will ask to switch to the insecure mode in order to send logs successfully. Run the automatic configure-linux bash script below to setup rsyslog. Alternatively, you can manually configure rsyslog.

curl -O


  • SUBDOMAIN: your account subdomain that you created when you signed up for Loggly
  • TOKEN (optional): your customer token from the source setup page
  • USERNAME: your Loggly username

Script Usage

configure-linux [-a loggly auth account or subdomain] [-t loggly token (optional)] [-u username] [-p password (optional)] [-s suppress prompts (optional)] [--insecure {Insecure mode} (optional)] [--force-secure {Force Secure Mode} (optional)]


  • Configures rsyslog to send logs to Loggly

Suppress prompts

  • Suppressing the interactive prompts allows you to run it automatically using default settings

Insecure Mode

  • Insecure mode allows you to send your logs insecurely on port 514

Force Secure Mode

  • Force secure will send the logs forcefully to secure mode. It prevents swiching to insecure mode even if package rsyslog-gnutls could not be downloaded. This will set the TLS configurations. On manually installing the rsyslog-gnutls package, secure sending will be started.

The script will perform over 10 system checks below to make sure your system is compatible with Loggly and that it can successfully send logs to Loggly. It also logs the status of your setup experience to Loggly so our support team can help if you have trouble.

Sending Logs from a Windows Syslog Agent

Make sure to replace the CUSTOMER_TOKEN in the config file with your specific token found under Source Setup > Customer Tokens.

1. Install Nxlog

Download the latest version of nxlog. It’s probably easiest to choose the Windows msi file which includes an installer.

2. Copy the Configuration

Open the Nxlog configuration file at:

C:\Program Files (x86)\nxlog\conf\nxlog.conf

Replace the entire configuration file by pasting the following, and replacing the variables below.

## This is a sample NXLog configuration file created by Loggly. June 2013
## See the nxlog reference manual about the configuration options.
## It should be installed locally and is also available
## online at

## Please set the ROOT to the folder your nxlog was installed into,
## otherwise it will not start.
#define ROOT C:\\Program Files\\nxlog
#define ROOT_STRING C:\\Program Files\\nxlog
define ROOT C:\\Program Files (x86)\\nxlog
define ROOT_STRING C:\\Program Files (x86)\\nxlog
define CERTDIR %ROOT%\\cert

Moduledir %ROOT%\\modules
CacheDir %ROOT%\\data
Pidfile %ROOT%\\data\\
SpoolDir %ROOT%\\data
LogFile %ROOT%\\data\\nxlog.log

# Include fileop while debugging, also enable in the output module below
#<Extension fileop>
# Module xm_fileop

<Extension json>
  Module xm_json

<Extension syslog>
  Module xm_syslog

<Input internal>
  Module im_internal
  Exec $Message = to_json(); 

# Windows Event Log
<Input eventlog>
  # Uncomment im_msvistalog for Windows Vista/2008 and later
  Module im_msvistalog

  #Uncomment im_mseventlog for Windows XP/2000/2003
  #Module im_mseventlog
  Exec $Message = to_json();

<Processor buffer>
  Module pm_buffer
  # 100Mb disk buffer
  MaxSize 102400
  Type disk

<Output out>
  Module om_tcp
  Port 514

  Exec to_syslog_ietf(); 
  Exec $raw_event =~ s/(\[.*])//g; $raw_event = replace($raw_event, '{', '[CUSTOMER_TOKEN@41058 tag="windows"] {', 1);
  #Use the following line for debugging (uncomment the fileop extension above as well)
  #Exec file_write("C:\\Program Files (x86)\\nxlog\\data\\nxlog_output.log", $raw_event);

<Route 1>
  Path internal, eventlog => buffer => out

Replace the above variables:

  • CUSTOMER_TOKEN: Replace with your own customer token
  • ROOT and ROOT_STRING: If you are in 32-bit Windows, uncomment the top root path on lines 8 and 9 to use the 32-bit program files folder then comment the two below.

Note: The pm_buffer module supports disk based message buffering and helps in storing logs during network outage, it also send buffered logs when network connection is re-established. You can increase or decrease the MaxSize under the pm_buffer module according to your requirement of disk buffer.

3. Restart Nxlog

Open the Services tool in the Start menu, find nxlog in the list, and then restart the service.
