Re: How to Take Snapshots of TCP/IP Connection Status info at Predefined Intervals (Monitor TCP/IP Connections)

Have you tried with something like this?

TRCCNN SET(*ON) TRCTYPE(*IP) TRCFULL(*STOPTRC) TRCTBL(IBMi01_TRACE_01) SIZE(1024 *MB)

TRCCNN SET(*OFF) TRCTBL(IBMi01_TRACE_01) OUTPUT(*STMF) TOSTMF('/home/USER/ibmi01_trace_01.pcap' *YES)

The .pcap file works with WireShark

Hello there,



I would like to take snapshots defined at some interval (e.g., every 15
minutes) of the active TCP/IP connections on my system, dumping them to a
spool or stream file. Traditionally, I would go WRKTCPSTS *CNN (or NETSTAT
*CNN) and sort the list to my liking. This is great for one-offs, but I need
to monitor the connections throughout the day, preferably with me not at a
green screen hitting F5 every 15 minutes, followed by F6. The following
archived post bears some similarity:
https://archive.midrange.com/midrange-l/200208/msg01652.html.



I am aware of the "List Network Connections (QtocLstNetCnn) API" found here
(https://www.ibm.com/docs/en/i/7.4?topic=ssw_ibm_i_74/apis/qtoclstnetcnn.htm
) and the QSYS2.NETSTAT_INFO view. The tools are there. What I lack is the
knowledge to use them. Any suggestions?
