Detailed Description

Basic detail collection class of System Usage metrics for the Monitor History database.

Properties represent metrics which get collected every few minutes by the MONAPP Application Monitor process when the Monitor.System.HistorySys class is "active".

For details, see History Monitor.

Member Function Documentation

Export()

_.Library.Status Export ( _.Library.String  FileName, _.Library.TimeStamp  Start, _.Library.TimeStamp  End  )

static

Export SystemUsage data for a time range in CSV format.

The default is all of the data

currently in the SysData class.

The default FileName is HistorySys_config_date_time.csv in the MGR directory.
'Start' and 'End' times (if necessary) are in YYYY-MM-DD HH:MM:SS format.

ExportDB()

_.Library.Status ExportDB ( _.Library.String  FileName, _.Library.TimeStamp  Start, _.Library.TimeStamp  End, _.Library.String  Database  )

static

Export Database data for a time range in CSV format.

The default is all of the data

currently in the SysData class.

The default 'FileName' is HistoryDB_config_date_time.csv in the MGR directory.
'Start' and 'End' times (if necessary) are in YYYY-MM-DD HH:MM:SS format.
The 'Database' argument can select (by name) a single database to export. Otherwise, data for all databases is exported and the database name is exported as a column.

Purge()

_.Library.Integer Purge ( _.Library.Integer  Keep )

static

Purge SysData interval data, keeping the last 'Keep' days.

This is typically called at

the start of each day from the Monitor.System.HistorySys 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)

Returns the number of entries purged.

Summary()

_.Library.Status Summary ( _.Library.Integer  Day )

static

Collect summaries of the SysData metrics for a day into the Hourly/Daily database.

This is typically done automatically by Monitor.System.HistorySys 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).
