SYS.History.Performanceserial class SYS.History.Performance
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
ECP App Server database blocks added to cache
ECP App Server database blocks purged by buffer allocation
ECP App Server database blocks purged as requested by a Data Server
ECP App Server bytes received
ECP App Server bytes sent
ECP Data Server active client connections ** DEPRECATED ** This property is not a 'counter' like the rest of this class, and does not produce values suitable for per-second summaries. All values will now be zero.

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".
