Is there a way to retrieve more information about the remote end that initiated the connection using the handle passed into .z.po? I have the .z.a (ip address) and .z.u (user id). I was hoping to find out more about the other end of the connection. If the other end of the connection is a q process, I can determine that by using the handle (h) and requesting .z.X from the handle (h".z.X") to find out what command line was used to initialize the process. But if I use this h".z.X" call on a non q process (maybe c code) handle it doesn’t return. Are there calls I can make to a handle that will reveal more information about the handle.

 

Thank you.

Hi trosales,

You could write a callback function to gather more information from your q process and return the result, or perhaps consider extending the .z functionality, for example see Using modified .z functions to trace, monitor and control execution Knowledge Base kdb+ and q documentation - Kdb+ and q documentation (kx.com)
