SYS.History.Performance

Class SYS.History.Performance Extends %SerialObject [ System = 4 ]

A list of Performance metric properties for the PerfData interval collection class.

These properties are all 'counter' types and the interval data is collected as deltas, which represent the change in the counter over the last interval. When this data is summarized into hourly and daily values, the data is normalized to per-second rates.

For details, see History Monitor.

Methods​

PropList​

ClassMethod PropList() As %String [ Internal ]

Fetch a list of detail properties for this class These are the "counter" type properties for which deltas and totals can be calculated.

SetSummary​

ClassMethod SetSummary(ByRef Function As %String, Period As %String) As %Status

Configure the summary methods for this class for either the Hourly or Daily summaries. This is a comma-delimited list of functions to use for the summary. The available functions are Average, Maximum (high-water mark), Minimum (lowest value), Standard Deviation, Median, and Total. These are abbreviated in the 'Function' argument as "Avg", "Max", "Min", StDev", Med", and "Tot". If nothing is specified, the default is "Avg,Max,StDev". You may also specify the string "None" for a summary period to disable that summary.

A null 'Function' argument will return the current summary setting in the 'Function' variable.

The 'Period' argument can be either "Hourly" or "Daily".
