Citrix Insight Services is a free cloud service from Citrix that allows us to upload detailed logging information and configuration from our NetScaler and scan it against a set of rules to see if there are any issues or best practices that we have not configured. It is also often used in conjunction with Citrix support cases, and Citrix will often tell you to upload data to Insight Services before it can continue troubleshooting.
In order to generate log files for Citrix Insight Services, we need to go into System | Diagnostics, and then from there click on Generate Support File, or use the following command:
Show techsupport
This will generate a tar.gz file under the folder /var/tmp/support/collector_ip_data.tar.gz, which can be downloaded to a local machine using, for instance, winSCP or any other FTP-based client.
You can also enable a feature called Call Home, which will allow NetScaler to automatically upload a tech support tar.gz to insight...
