Our enterprise utilizes Citrix to deliver applications to our 5000 users. We are looking to upgrade Citrix or change the delivery solution altogether. We want to baseline our current solution and then compare this baseline to any proposed solution. Can Splunk measure the end to end performance of our current solution? We want quantified response time end to end. So, if a user performs a request of the system utilizing a specified application, going through Citrix, how long does it take to perform this action.
Take a look at the newly released preview of http://splunk-base.splunk.com/apps/48390/splunk-app-for-citrix-xenapp I believe it does everything you are asking for.
