Introduction to Linux Syslog and What it Does

Because of its versatility, reliability, and security, Linux has emerged as the most powerful and well-liked platform in the era of operating systems. The Syslog system is a crucial part of the Linux operating system but is frequently overlooked by end users. Syslog is an essential component that saves and manages log messages produced by running services and other installed programs in a Linux system. In this post, we’ll talk about Linux Syslog’s creation and examine its purpose and features.


For application messages and logging systems, Syslog is recognized as a standard protocol in Linux. It enables the transmission of log messages from numerous services and applications to a single, central place. Those central locations are referred to as Syslog servers. These log messages must be gathered and stored by it for further troubleshooting and analysis. Other operating systems, including BSP, macOS, and numerous more, now frequently use Syslog.

How does Syslog Work?

Introduction to Linux Syslog and What it Does

Syslog consists of three vital components:

  • Syslog Server
  • Syslog Client
  • Syslog Protocol

Syslog Server

The Syslog server, often known as syslogd, collects all incoming log messages from a certain port while running in the background. Receiving messages from various syslog clients, processing them, and then storing them in log files for particular services or applications are its duties.

Syslog Client

This component works for generating and sending log messages to a Syslog server. Services and applications running on Linux systems can use system calls or syslog libraries to transmit log messages to the syslog server (syslogd). The Syslog client is responsible for transmitting crucial details such as hostname, actual log content, timestamp, and severity level. 

Syslog Protocol

The Syslog protocol contains a set of rules that are defined for effective communication between the Syslog server and the client. It also defines the format of log messages that can be stored in the Syslog server, responsible for specifying different severity levels such as starting from debugging to emergency, allows the admin to prioritize and filter the log messages based on their need and importance.

Key functionalities

Syslog is equally important for both system administrators and developers. Here are some of its key benefits and functionalities


The Syslog is flexible enough that it allows the administrators to configure the log actions and destinations as per desire and need. Log messages can be stored in files locally, transmitted to servers, trigger notifications, forward the log files to other Syslog servers, and can also work on scripts containing specific conditions.

Centralized Logging

Syslog offers a centralized approach to log management. This centralized-based approach helps the administrator to access the log messages and analyze them for multiple services and applications from a single place because all the log messages are stored in a single server. Therefore, it makes troubleshooting easier along with auditing and monitoring the activity.


Syslog is extremely scalable when it comes to scalability, which makes it more appropriate for a large number of devices and systems within an environment. Syslog is capable of handling many clients’ including services and applications log messages simultaneously and ensuring that no logs are lost or missed.

Long term Storage

The Syslog authorizes long-term storage and log file archiving. Administrators can easily control the size of log files by configuring log rotation policies and also retention periods, which can ensure the logs are properly retained for historical analysis and compliance.

Prioritization and Filtering

The Syslog enables the administrators to apply filters on log messages based on sources, severity levels, and other criteria. This prioritization and filtering allow the administrators to focus on critical events and reduce the number of less important logs.

Crestron Virtual Processors running on Linux with VC4

Crestron’s VC 4 documentation provides some guidance (and a configuration example) for non-Linux experts on how to filter entries from the main syslog into a dedicated Crestron log file. While this is useful information, users of VC4 in a server environment will soon find that this level of filtering is not suitable for quick review and the resultant logs are still too noisy to be useful.

The team at LCD has some hints and tips below as to how to make the syslog filtering work for your vc4 architecture.

Filtering for Logic Engine and SimplPlus

Log entries coming from simpl Windows programs running on VC4 have two patterns, One is logging from the program Logic Engine and the 2nd is from the Simpl+ process. The entries below in the config file create two filtered log files and filter entries for each of the processes into the respective files.

The log entries below are from a room named “55” which is running a Simpl Windows program.

We can use the naming of different entries in the syslog to filter into more granular log files.

See the example below for details of how to create a single log file for Logic engine and Simpl Plus Logs.

The code below shows a snippet from the  /etc/rsyslog.d/ conf file.

Filtering per Room or Group of Rooms

One step further you can create a dedicated log with messages from the specific room logic engine or group of Engines you want to capture.

For example, if your rooms have a standard naming pattern in VC4 then you can leverage this to filter log messages from them into a single file.

In Summary

Setting up granular logging can make a great difference in the time to diagnosis. If you need help configuring your systems to make the most of modern logging then contact us to find out more.

JetBrains Rider vs. Microsoft Visual Studio – The IDE Battle for Audio Visual Programmers

Once upon a time, in the realm of .NET development, a titan named Visual Studio stood a shoulder above the rest. Visual Studio was the supreme go-to tool for a long time, offering a vast and robust Integrated Development Environment (IDE) that even audio-visual programmers couldn’t resist in the epic showdown of JetBrains Rider vs. Microsoft Visual Studio – The IDE Battle for Audio Visual Programmers.

Seemingly, the honeymoon was over when a new contender emerged from the depths of innovation—JetBrains Rider! An upstart IDE shook the very dominance of Microsoft Visual Studio in the .NET world.

JetBrains Rider emerged as a worthy adversary, boasting a sleek interface, lightning-fast performance, and a host of cutting-edge tools.

Suddenly, developers were at a crossroads between loyalty to the tried-and-true Visual Studio and the allure of Rider’s modern charm. So, which side of the IDE battle should audio-visual programmers lean on?

While both IDEs are powerful and capable, distinctive differences can be a dealbreaker for some of us audio-visual programmers.

Microsoft Visual Studio: The Industry Standard

JetBrains Rider vs. Microsoft Visual Studio - The IDE Battle for Audio Visual Programmers

Microsoft Visual Studio has been a long-standing industry-standard IDE catering to a wide range of developers, including audio-visual programmers. Visual Studio Code is also a powerful tool in its own right!

One of Visual Studio’s key strengths lies in its robust ecosystem and vast community support. Its extensive documentation and tutorials make it easier for audio-visual programmers to find resources and solutions to common challenges.

Microsoft actively maintains and updates Visual Studio for compatibility with the latest technologies and frameworks. This is in addition to support for various programming languages, such as JavaScript, HTML, C#, C, C++, .NET, and others. Unfortunately, Microsoft removed the support for Java in 2017.

Visual Studio offers seamless integration with platforms like Crestron, and the developers can leverage the platform’s full potential.

JetBrains Rider: Unleashing Cross-Platform Power

JetBrains Rider vs. Microsoft Visual Studio - The IDE Battle for Audio Visual Programmers

JetBrains Rider, on the other hand, is a robust IDE with cross-platform capabilities. It is versatile to support various programming languages, including C#, C++, JavaScript, and more.

Rider supports plugins developed by ReSharper and IntelliJ platform and others, but the standout feature is Rider’s seamless integration with the JetBrains ecosystem.

This provides a consistent experience across the brand’s suite of tools.

A more notable advantage is Rider’s advanced code analysis and refactoring capabilities. The IDE bundles debugging tools, intelligent code completion, and a powerful search engine, allowing you, as the developer, more straightforward navigation through large projects.

Rider’s excellent support for Git version control is really usable (although we complement it with a tool called gitkracken), as it simplifies workgroup collaboration. But it’s not so simple as Visual Studio is the defacto standard Rider suffers.

The reason is that the majority of learning platforms and example code videos all use visual studio as their IDE and the same is true for audio-visual programming might fall short. Official documentation and support for specific platforms, like Crestron, may be lacking. These can cause issues with the development process for applications meant for those platforms.

The Showdown

Both Rider and Visual Studio allow the consumption of privately hosted NuGet packages in the epic showdown of JetBrains Rider vs. Microsoft Visual Studio – The IDE Battle for Audio Visual Programmers – which is beneficial for audio-visual programmers relying on customized project packages. Such flexibility enhances productivity by enabling efficient management of dependencies.

This broad support helps automate the programming process and extend the feature list – invaluable for audio-visual coding.

But that doesn’t mean Visual Studio falls short regarding plugins. It has its bunch to enhance the coding process, even though it may struggle to match Visual Studio in that way. Check your current project requirements before migrating.

Rider takes the day when it comes to code inspection. No doubt Microsoft Visual Studio can detect issues with a handful of languages, but JetBrains Rider stretches this to multiple languages. For instance, Rider’s code inspections are over 1600 compared to 800 for Visual Studio.

Rider also gallops ahead regarding user experience with a clean, intuitive, and responsive interface. Users can choose keyboard bindings and color schemes, among other customizing features. Rider is also a savvy pick for those that prioritize performance. The JetBrains IDE starts and codes faster than Visual Studio. On the other hand, there have been reports of a freezing Visual Studio, especially in the face of solutions with many projects.

Microsoft Visual Studio shines with its extensive documentation, robust ecosystem, and strong support for platform support with edge case examples ( which is where we sit in the Audio Visual world). But Rider gets one over Visual Studio for its compatibility with Linux.

Ultimately, the choice between Rider and Visual Studio boils down to individual preferences, specific project requirements, and the targeted audio-visual platforms. Performance and familiarity with the IDE also significantly influence your choice.

But whether you prioritize cross-platform power or comprehensive manufacturer support, both IDEs offer robust features that can fuel your audio-visual programming endeavors.
