Basic detail collection class of Performance metrics for the Monitor History database.
Properties represent metrics which get collected every few seconds by the %MONAPP
Application Monitor process when the %Monitor.System.HistoryPerf class is "active".
The values stored for most properties are deltas calculated from the last interval.
Export PerfData data for time range in CSV format. The default is all of the data
currently in the PerfData class. Note that Write Daemon cycle properties are exported
as the high-water mark for the cycles during an interval.
The default FileName is HistoryPerf_config_date_time.csv in the MGR directory.
'Start' and 'End' times (if necessary) are in YYYY-MM-DD HH:MM:SS format.
Purge PerfData interval data, keeping the last 'Keep' days. This is typically called at
the start of each day from the %Monitor.System.HistoryPerf class, using the current
system default for 'Keep' (see the SetPurge() method). The 'Keep' argument allows
you to over ride the system default (a value of "0" or "" uses the system default)
Set the system parameter for the number of days of detail data to keep.
Initial system default is 7 days. Return value is the previous setting, and executing
this method with a "" argument will return the current setting without modifying it.
Collect summaries of the PerfData metrics for a day into the Hourly/Daily database.
This is typically done automatically by %Monitor.System.HistoryPerf at the
beginning of each day (for the previous day), but could be called manually
if there's a problem.
The 'Day' argument sets the end date of the collection, with the default
of "0" being the start of today (i.e. $H+Day), which would collect everything for
yesterday. A "-1" would collect the day before yesterday; a "1" would collect
today (as much as there is).
