## Introduction[​](#introduction "Direct link to Introduction")

This document explains how to configure rsyslog to support TLS connections, which is necessary for sending logs to Coralogix syslog endpoints.

## Prerequisites[​](#prerequisites "Direct link to Prerequisites")

* Ubuntu 22.04 (or newer)

## Configuration[​](#configuration "Direct link to Configuration")

**STEP 1**. Install the `gtls driver` and `ca-certificates`:

```
sudo apt update -y

sudo apt install rsyslog-gnutls ca-certificates
```

**STEP 2**. Modify the rsyslog configuration file:

```
$DefaultNetstreamDriver gtls $DefaultNetstreamDriverCAFile /etc/ssl/certs/ca-certificates.crt $ActionSendStreamDriverMode 1 $ActionSendStreamDriverAuthMode x509/name $ActionSendStreamDriverPermittedPeer *.coralogix.com $template CoralogixSyslogFormat,"{\"fields\": {\"private_key\":\"xxxx\",\"application_name\":\"vagrant\",\"subsystem_name\":\"syslog\"},\"message\": {\"message\":\"%msg:::json%\"}}\n" *.* @@syslog.eu2.coralogix.com:6514;CoralogixSyslogFormat
```

**STEP 3**. Restart rsyslog:

```
sudo systemctl restart rsyslog
```

## Troubleshooting[​](#troubleshooting "Direct link to Troubleshooting")

**STEP 1**. Check the status of the rsyslog service:

```
sudo systemctl status rsyslog
```

**STEP 2**. Check for any errors in the journalctl logs:

```
sudo journalctl -f -u rsyslog
```
