System Requirements

The WinSyslog Service has minimal system requirements. The actual minimum requirements depend on the type of installation. If the Client is installed, they are higher. The service has very minimal requirements, enabling it to run on a large variety of machines - even highly utilized ones.


  • The client can be installed on Windows 2003 and above. This includes Windows XP, Windows 2008/2012/2016/2019 servers, Windows Vista, and Windows 7/8/10. The operating system variant (Workstation, Server …) is irrelevant.
  • The client is suited for 32bit and 64bit operating systems. It runs automatically on each platform in 32Bit or 64Bit mode.
  • The client uses Microsoft .Net Framework technology. The Installer will automatically install the necessary .Net Framework components before installation. A network connection maybe required in order to download additional components.
  • The client requires roughly 8 MB RAM in addition to the operating system minimum requirements. It also needs around 5 MB of disk space.


  • The service has fewer requirements.
  • It works under the same operating system versions.
  • At runtime, the base service requires 5 MB of main memory and less than 5 MB of disk space. However, the actual resources used by the agent largely depend on the services configured.
  • If the RSyslog Windows Agent shall just monitor the local systems event log, impact on the monitored system is barely noticeable, if at all visible.
  • If the RSyslog Windows Agent acts as a central Syslog server receiving hundreds of messages per second, it needs many more resources. Even then, the actual load is depending on the actions carried out. As such, there is no single guideline for hardware sizing. It needs to be adapted to the expected workload. We have created an article on performance optimization for syslog server operations, which you may want to read.
  • Please note however, that the service is specifically optimized to handle high throughput including message bursts (for example received via syslog).
  • If you expect high volume burst and carry out time consuming actions (for example database writes), we highly recommend adding additional memory to the machine. Please note that the 32Bit Service is limited to 2GB of usable memory. The 64Bit version does not have any limit. A typical Syslog message (including overhead) takes roughly 4-8 KB. With 1024 MB, you can buffer up to 100,000-200,000 messages in 1024 MB.
  • Please note that the RSyslog Windows Agent is capable of storing such bursts temporarily in memory even if the machine would otherwise be too slow to process the messages.

Adiscon LogAnalyzer

  • Adiscon LogAnalyzer requires a local webserver installed. Microsoft Internet Information Server (IIS) version 4 (or higher) or Apache is possible as Adiscon LogAnalyzer is a PHP based application. Adiscon LogAnalyzer is an optional component and not mandatory. We recommend to use it on Apache in conjuction with PHP5 such as included in the package WAMP.
