Citrix Insight Services Citrix self support tool called CIS, formerly known as Tools-as-a Service (TaaS). Insight Services takes a XenServer status report, and analyses it to determine if there are any operational issues present in the deployment. A best practice is to upload a report after installing a XenServer host to determine if any issues are present which can result in latent performance or stability problems. CIS is used extensively by the Citrix support teams, but doesn't require a commercial support contract for end users link for the tool https://taas.citrix.com/AutoSupport/

The quick reference guide below will help diagnose and rule out some common issues experienced in the 3PAR arrays.  CLI COMMAND – “STATVLUN” measures the round trip time of an IO as seen by the system. Running STATVLUN in the following order should lead to the resolution of a few performance issues: 1)      “statvlun –ni”   – The STATVLUN command without any switches will show the round trip time of IO on each path for exported Virtual Volumes. This is helpful to determine if there is a multipathing issue. The “-ni” flag will eliminate any inactive volumes. 2)      “statvlun –vvsum –ni –rw”   This will show you the round trip time of the IO to each volume with the paths condensed for consolidated reporting.  This is great to see an overall picture of what is going on The “-rw” flag will break the IO down into Reads & Writes. 3)      “statvlun –hostsum –ni –rw”   The output of this command will show you the round trip time of the IO organized to the host le
