  • Services Running
    (see: sys.dm_server_services)

    (see: sp_spaceused and sp_MSforeachtable / sys.master_files + sys.databases / msdb.sys.dm_io_virtual_file_stats)
  • Error Log (Agent and DB)
    (see: xp_readerrorlog)

  • overview of sessions (users)
    (see: sys.dm_exec_sessions, kill)
