VCS attributes enabling agent statistics

This topic describes the attributes that enable VCS agent statistics.

MonitorStatsParam

A resource type-level attribute, which stores the required parameter values for calculating monitor time statistics.

static str MonitorStatsParam = { Frequency = 10, 
ExpectedValue = 3000, ValueThreshold = 100, 
AvgThreshold = 40 }

  • Frequency: Defines the number of monitor cycles after which the average monitor cycle time should be computed and sent to the engine. If configured, the value for this attribute must be between 1 and 30. It is set to 0 by default.

  • ExpectedValue: The expected monitor time in milliseconds for all resources of this type. Default=3000.

  • ValueThreshold: The acceptable percentage difference between the expected monitor cycle time (ExpectedValue) and the actual monitor cycle time. Default=100.

  • AvgThreshold: The acceptable percentage difference between the benchmark average and the moving average of monitor cycle times. Default=40

MonitorTimeStats

Stores the average time taken by a number of monitor cycles specified by the Frequency attribute along with a timestamp value of when the average was computed.

str MonitorTimeStats{} = { Avg = "0", TS = "" }

This attribute is updated periodically after a number of monitor cycles specified by the Frequency attribute. If Frequency is set to 10, the attribute stores the average of 10 monitor cycle times and is updated after every 10 monitor cycles.

The default value for this attribute is 0.

ComputeStats

A flag that specifies whether VCS keeps track of the monitor times for the resource.

boolean ComputeStats = 0

The value 0 indicates that VCS will not keep track of the time taken by the monitor routine for the resource. The value 1 indicates that VCS keeps track of the monitor time for the resource.

The default value for this attribute is 0.
