Installing the NetScaler web logging (NSWL) client

August 1, 2023

Contributed by:

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	Ubuntu, SUSE Linux, CentOS, Red Hat Enterprise Linux released in 2016 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.

Download NSWL client

You can obtain the NSWL client package from either the NetScaler product CD or the NetScaler downloads site. Within the package there are separate installation packages for each supported platform.

To download the NSWL client from the Citrix website

Log on to Citrix by accessing the URL https://www.citrix.com/downloads/citrix-adc/.
Navigate to a particular NetScaler release version and look for its Firmware.
Click Firmware (for example, NetScaler Release (Feature Phase) 13.0 Build 52.24).
In the NetScaler Release (Feature Phase) Build page, go to Weblog Clients section.
The section allows you to download Weblog clients for Windows, Linux, and BSD.

Install NSWL client on Solaris

To install the NSWL client, perform the following operations on the system where you downloaded the package.

Extract the nswl_solaris-<release number>-<build number>.tar file from the package.
Copy the extracted file to a Solaris system on which you want to install the NSWL client.
Extract the files from the tar file with the following command:

tar xvf nswl_solaris-9.3-51.5.tar

A directory Weblog is created in the temporary directory, and the files are extracted to the Weblog directory.

Install the package with the following command:

pkgadd -d
The list of available packages appears. In the following example, one Weblog package is shown:

1 NSweblog NetScaler Weblogging (SunOS,sparc) 7.0

You are prompted to select the packages. Select the package number of the Weblog to be installed.

After you select the package number and press Enter, the files are extracted and installed in the following directories:

/usr/local/netscaler/etc
/usr/local/netscaler/bin
/usr/local/netscaler/samples

To check whether the NSWL package is installed, run the following command:

pkginfo | grep NSweblog
To uninstall the NSWL package, run the following command:

pkgrm NSweblog

This command extracts the files and installs them in the following directories.

/usr/local/netscaler/etc
/usr/local/netscaler/bin
/usr/local/netscaler/samples

To uninstall the NSWL package, run the following command:

rpm -e NSweblog
To get more information about the Weblog RPM file, run the following command:
