SYS.Monitor.Health.Control
hidden class SYS.Monitor.Health.Control extends %SYS.Monitor.AbstractSubscriber
Registered as a Subscriber to the System Monitor to handle all of the Health Monitor Sensors. This may create Charts for a Sensor (for multiple periods) if the Sensor is evaluated based on deviation from normal values.Method Inventory

Methods
classmethod CalcChartStats(ByRef Readings As %List, ByRef Mean As %String, ByRef Sigma As %String, ByRef HighValue As %String, ByRef WarnValue As %String, ByRef stat As %Integer) as %Status
Calculate mean and standard deviation based on list of values
stat returns error code:
-1 - too few samples. 13 is minimum.
0 - success
classmethod CalcHigh(Mean As %Integer, Sigma As %Integer, High As %Integer, ByRef HighValue, ByRef WarnValue) as %Status
Calculate alert value and warning value given high, mean, and sigma
classmethod CalcShiftedMean(Samples As %List, ByRef Z As %String, ByRef Trend As %Integer = 0) as %Status
Calculate Shifted Mean.
The first element is the historic base value. The remainder are samples. A minimum of 5 samples is required
to compute a meaningful statistic.
Trend: 0: No trend, +1: Rising shifted mean, -1: Lowering shifted mean
Return code: 0 - insufficient data, 1 sufficient data, -1 an error: test $ze
Calculate Trend statistic z based on list of samples.
The first element is the historic base value. The remainder are samples. A minimum of 5 samples is required
to compute a meaningful statistic.
Trend: 0: No trend, +1: Rising trend, -1: Lowering trend, +2: Rising shifted mean, -2: Lowering shifted mean
Return code: 0 - insufficient data, 1 sufficient data, -1 an error: test $ze
method HealthAlert(sensor As %String, item As %String, rule As %Integer, severity As %Integer, valuelist As %List) as %Status
Save all readings after an out of bounds
classmethod InitializeDB() as %Status
final classmethod InitializeSensor(Sensor As %String, Threshold As %Integer = 0, MaxVal As %Integer = 0, MaxMult As %Integer = 0, WarnVal As %Integer = 0, WarnMult As %Integer = 0) as %Status
This method is called to set details of a sensor.
Name, type, threshold, max value, max multiplier
Returns 0 if already exists, 1 if ok, status code if problem saving the sensor object.
method LoadSensors() as %Status
Randomness test.
Calculate trends from the Median. In a normally distributed sample, there should not be significant rise or lowering from the median. Return code: 0 - insufficient data, 1 sufficient data, -1 an error: test $ze
Evaluate running averages
