Configuring Citrix NetScaler

To configure the Citrix NetScaler to send logs to the LCP, follow the steps below.

  1. Verify if the hostname is configured.

  • Login to the NetScaler Web interface as an Administrator.

  • Navigate to Configuration > Settings.

  • Click on Host Name, DNS IP Address and Time Zone.

  • In the Host Name text box, verify if the host name is present.

a) If the host name is configured already, no action is required.

b) If the text box is empty, type a host name without space.

c) In the DNS IP Address text box, verify if the local DNS IP address is added.

d) In the Time Zone text box, type your time zone.

2. Configure the Syslog server action.

  • Login to the NetScaler Web interface as an Administrator.

  • Go to Configuration > System > Auditing > Syslog > Servers.

3. Do the following steps to Create Auditing Server window. 

  • Enter the Syslog details like Name, Server Type, IP address of the LCP and Port.

  • Select Log Levels as Custom.

  • Enable all checkboxes except DEBUG level in the configuration.

  • Select LOCAL0 from Log Facility drop-down.

  • Select MMDDYYYY from Date Format drop-down.

  • Select Time Zone as GMT.

  • Uncheck all the check boxes as per below screenshot.

  • Click OK to create the auditing server.

4. Binding the created audit policy to the server.

  • Go to Configuration > System > Auditing > Syslog and click the Policies tab.

  • In the Name* text box, type a name for the policy.

  • In the Server* drop-down list, select the policy from the previous section and click Create.

5. Right-click the created Auditing Policy and go to Action > Global Bindings and click Add Binding

6. In the Policy Binding window,

  • In the Select Policy* text box, type the created audit policy.

  • In the Binding Details section, in the Priority* text box type 120 as it is the default priority and click Bind.

 Note: Priority is a numeric value that indicates when this policy is evaluated relative to other policies. Access Gateway gives precedence to a policy with lower priority.
