NXLog TLS Configuration

You can securely send your logs to Loggly using TLS encryption. This guide shows you how to set it up for nxlog and is tested on Windows Server 2012.

NXLog TLS Configuration Setup

1. Install necessary security Certificates

Download the certificate file https://logdog.loggly.com/media/logs-01.loggly.com_sha12.crt

Then place it into C:\Program Files*\nxlog\cert directory.

copy logs-01.loggly.com_sha12.crt C:\Program Files*\nxlog\cert

2. Update the NXLog Configuration file

Open your configuration file (nxlog.conf) and update the output module by replacing the configuration given below.

<Output out>
   Module om_ssl
   Host logs-01.loggly.com
   Port 6514
   CAFile %CERTDIR%/logs-01.loggly.com_sha12.crt
   AllowUntrusted FALSE
   Exec to_syslog_ietf(); $raw_event = replace($raw_event, 'NXLOG@14506', 'TOKEN@41058 tag="windows"] [', 1);
</Output>

Replace:

Restart NXLog after saving changes and send some Windows logs.

3. Verify Events

Search Loggly for events with the tag as windows over the past hour. It may take few minutes to index the event. If if doesn’t work, see the troubleshooting section below.
