HAProxy is a free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers. HAProxy has a lot of features and because it is located between your infrastructure and your clients, it can give you a lot of information about either of them.
This setup guide will show you how to forward your HAProxy logs to SEKOIA.IO by means of an rsyslog transport channel. On most linux servers, two packages need to be installed: rsyslog and rsyslog-gnutls.
1. Download the certificate
In order to allow the connection of your rsyslog server to the SEKOIA.IO intake, please download the SEKOIA.IO intake certificate:
$ wget -O /etc/rsyslog.d/SEKOIA-IO-intake.pem https://app.sekoia.io/assets/files/SEKOIA-IO-intake.pem
2. Configure the Rsyslog server
Open or create a new Haproxy configuration file for rsyslog:
sudo vim /etc/rsyslog.d/49-haproxy.conf
Paste the following rsyslog configuration to trigger the emission of haproxy logs by your rsyslog server to SEKOIA.IO.

In the above
template instruction, please replace
YOUR_INTAKE_KEY variable with your intake key.
3. Restart rsyslog
$ sudo service rsyslog restart
4. Enjoy your events
Go to the events page to watch your incoming events.
