Period definition
Period captures definition
Analysis period start marker event name
Analysis period end marker event name (requires --period-begin)
Optional, list of event field names used to match period markers (default: cpu_id)
Optional, list of event field names used to match period marker. If none specified, use the same --period-begin-key
Optional, define a fixed key value to which a period must correspond to be considered.
