Hi,

WLSDM able to monitor AdminServer. Please find the documentation here.

https://wlsdm.com/docs/README#X.MonitoringAdminServer&WL-OPC

You can monitor AdminServer via WLSDM standalone process or WL-OPC. We’re recommending to use WL-OPC for monitoring WebLogic Admin server. https://wlsdm.com/wl-opc

Kind Regards…
