Features at a glance
Key features include a modular design, support for on-demand disk buffering, email alerting, on-the-wire message compression, support for all GNU/Linux operating systems, support for mainstream architectures, state-of-the-art security, high-performance, as well as the ability to convert text files to the syslog format.
Among other features we can mention multi-threading support, the ability to filter any part of a syslog message, and support for syslog over the TCP (Transmission Control Protocol), TLS (Transport Layer Security), SSL (Secure Sockets Layer) and RELP (Reliable Event Logging Protocol) protocols.
In addition, the program supports the MySQL, Oracle and PostgreSQL database servers, provides a fully configurable output format, and it is suitable for enterprise-class relay chains. It is dubbed by its developers as a swiss army knife of logging.
Delivers over one million messages per second
When limited processing is in effect, the rsyslog software is capable of delivering over one million messages per second to local destinations. Remote destinations are also supported and rsyslog those a stunning good job.
Getting started with rsyslog
To use the application, you will have to first install it on your GNU/Linux system, either by using the universal sources archive distributed for free on Softpedia or the pre-built binary packages from the default software repositories of your distribution.
After installation, you can start the rsyslog daemon by running the “rsyslogd” command (without quotes) in a terminal emulator, follow by one of the available options. To see the supported options, run the “rsyslogd --help” command, without quotes.

- behaviour change: "msg" of messages with invalid PRI set to "rawmsg". When the PRI is invalid, the rest of the header cannot be valid. So we move all of it to MSG and do not try to parse it out. Note that this is not directly related to the security issue but rather done because it makes most sense.
