Controlling the Message Statistics Facility

The Message Statistics facility allows accumulation and display of statistics for the messages or commands issued by the system on which Control‑O is active.

The Message Statistics facility counts messages and commands by message or command ID. Each time a message or command is displayed, the counter for the corresponding entry in the Statistics file is incremented. When a new message ID or %%$STATID value is detected, a new entry is opened in the Statistics file.

Statistics accumulation is normally started automatically when Control‑O is brought up. However, when necessary, accumulation of statistics can be controlled by the following operator commands:

• Stop statistics accumulation

  F CONTROLO,STOPSTAT

• This command can be used if statistical accumulation is no longer required or if it becomes necessary to reformat the Statistics file without bringing down Control‑O.
• Start statistics accumulation

  F CONTROLO,STARTSTAT

• Reset statistics for all messages and commands

  F CONTROLO,RESETSTAT

  Note: All of the Control‑O modify commands and their parameters are listed in Control-O Monitor and CMEM Modify Commands.
