I need to document our port usage for 3rd party products for both production and R&D LPARs
On our R&D LPAR, we have up to 7 environments, each environment could have its own set of ports, depending on the 3rd party product.

I ran a NETSTAT, F13 sort by local port, F6=Print list, for both LPARs.
Also using NETSTAT interactively, F13 sort by local port,

I then created an Excel spreadsheet, manually populated.

1) One problem is that sometimes I need to see the job, which is only obtained by drilling down, 8=Display jobs
Can't see this on the F6=Print list.

2) Another problem is that some processes do not always appear, port is closed after being used.

Is there another or better way to document port usage?

Small sample below.
