SYSVIEW REST API interface allow to obtain same data as 3270 interface. Main requirement would be that SYSVIEW command screen is allowed to be used by XDI interface. Below two sample commands were successfully issue with RC200 but response was blank.
CTRANLOG STREAM GSVX.CICSLOGR.TRAN.SYSA DATE 31-07-2026 LINES 5 LIMIT 50000
CTRANLOG STREAM GSVX.CICSLOGR.TRAN.SYSA DATE 30-07-2026 PROGRAM ppppppp TRAN tttt LINES 100 LIMIT 50000
REST API
Conflicting parameters.
In this specific situation issue appears only when REST API is used, solution would be to use one of the parameters, either LIMIT or LINES.
In 3270 panel same command will return with data even both parameters are used.
