Control‑M allows accumulation of job execution information using its Statistics file. The accumulated information can then easily be viewed using option S in the Active Environment screen or the JOBSTAT command in Scheduling Definition screen.
Control‑M manages statistical information for the most recent job runs, up to a maximum of 200. In a multi‑CPU environment, Control‑M keeps this information for each CPU (SMF ID) in which the job executes.
