Installing the NetScaler web logging (NSWL) client

Last published : Sep 24, 2026
When you install NSWL, the client executable file (NSWL) is installed along with other files. The NSWL executable file provides a list of options that you can use. For details, see Configuring the NSWL Client.
Attention
The version of the NSWL client must be the same as NetScaler. For example, if the version of the NetScaler is 10.1 Build 125.9, the NSWL client must also be of the same version. Also, the web logging (NSWL) client works on both 32 bit and on 64 bit server machines. The download page has only a 32 bit weblog client. The 64 bit weblog client is available on request, and recommends you to contact NetScaler support for more information.
The following table lists the operating systems on which the NSWL client can be installed.
Operating system Version Hardware requirements Remarks
Windows Windows Server 2016 or later Processor - x86/amd64 CPU (1 GHz or higher), RAM - 4 GB (or higher) -
macOS macOS 8.6 or later Not supported on NetScaler 10.1 and later releases -
Linux All Linux distributions that are compatible with GNU C Library (GLIBC) version 2.31 or later Processor - x86/amd64 CPU (1 GHz or higher), RAM - 4 GB (or higher) -
Solaris Solaris Sun OS 5.6 or later Processor - UltraSPARC-IIi 400 MHz, RAM - 512 MB, Controller - SCSI Not supported on NetScaler 10.5 and later releases.
FreeBSD FreeBSD 6.3 or later Processor - x86/amd64 CPU (1 GHz or higher), RAM - 4 GB (or higher) For NetScaler 10.5, use only FreeBSD 8.4.
AIX AIX 6.1 - Not supported on NetScaler 10.5 and later releases.
If the NSWL client system cannot process the log transaction because of a CPU limitation, the Web log buffer overruns and the logging process reinitiates.
Caution
Reinitiation of logging can result in loss of log transactions.
To temporarily solve an NSWL client system bottleneck caused by a CPU limitation, you can tune the Web server logging buffer size on the NetScaler appliance. To solve the problem, you need a client system that can handle the site's throughput.
