Netscaler Application Firewall & Splunk Netscaler App

[gnanasekar6914]

Hi,
we have configured Netscaler Application Firewall to send logs via syslog to Splunk Netscaler App.
We can see correctly the logs on Splunk general search dashboard (under ns_log), but unfortunatly using the "Netscaler App" > "Web Application Firewall" we receive this message below.

Can you help me to understand what can be done to solve the issue? The objective is to use the predefined graphs and searchs.

Thanks.
