You can use the Netstat VDPT/-O and VCRT/-V report options to verify sysplex distributor workload. See z/OS Communications Server: IP System Administrator's Commands for more information on these commands.
Use the Netstat VDPT/-O report option with the DETAIL modifier on the distributing stack to confirm that there are target stacks available with server applications ready. This display will show only target stacks that are currently up and have joined the sysplex. The RDY field indicates how many, if any, applications the target TCP/IP, identified by its DestXCF Addr, has bound to DPort. If none, then this target TCP/IP will not receive any connection workload. The TotalConn field indicates how many connections this distributing TCP/IP has forwarded to the target TCP/IP. The ActiveConn field indicates how many connections the distributing TCP/IP has forwarded to the target TCP/IP that are currently active.
The following Netstat display command on the distributing stack, TCPCS, shows which target stacks are available with the server applications ready.

system general CP weight. The Proportional value is the Raw value modified by the expected CP usage proportion configured on the VIPADISTRIBUTE PROCTYPE statement for this application. |
The Raw value is the raw WLM
server-specific general CP weight. The Proportional value is the Raw value modified by the proportion of CP capacity that is currently being consumed by the application's workload, as compared to the other processors (zIIP and zAAP). |

system zAAP weight. The Proportional value is the Raw value modified by the expected zAAP usage proportion configured on the VIPADISTRIBUTE PROCTYPE statement for this application. |
The Raw value is the raw WLM
server-specific zAAP weight. The Proportional value is the Raw value modified by the proportion of zAAP capacity that is currently being consumed by the application's workload, as compared to the other processors (CP and zIIP). |
zIIP | The Raw value is the raw WLM
system zIIP weight. The Proportional value is the Raw value modified by the expected zIIP usage proportion configured on the VIPADISTRIBUTE PROCTYPE statement for this application. |
The Raw value is the raw WLM

When weighted active distribution is being used, the configured active connection weight for each target is shown as the WLM value in the Netstat VDPT/-O display. By using the DETAIL modifier on the display, the active connection counts (ActiveConn) are shown. The distributor balances incoming connection requests across the targets with a goal of having the number of active connections on each target proportionally equivalent to the configured active connection weight of each target.
