Response parameters JSON model

The ServiceAnomalyDetectionConfig object

Dynatrace automatically detects service-related performance anomalies such as response time degradations and failure rate increases. Use these settings to configure detection sensitivity, set alert thresholds, or disable alerting for certain services.

Element	Type	Description
metadata	ConfigurationMetadata
responseTimeDegradation	ResponseTimeDegradationDetectionConfig
loadDrop	LoadDropDetectionConfig
loadSpike	LoadSpikeDetectionConfig
failureRateIncrease	FailureRateIncreaseDetectionConfig

The FailureRateIncreaseDetectionConfig object

Configuration of failure rate increase detection.

Element	Type	Description
detectionMode	string	How to detect failure rate increase: automatically, or based on fixed thresholds, or do not detect. The detectionMode element can hold these values.
automaticDetection	FailureRateIncreaseAutodetectionConfig
thresholds	FailureRateIncreaseThresholdConfig

The FailureRateIncreaseThresholdConfig object

Fixed thresholds for failure rate increase detection.

Required if detectionMode is DETECT_USING_FIXED_THRESHOLDS. Not applicable otherwise.

Element Type Description

threshold

integer

Element	Type	Description
threshold	integer	Failure rate during any 5-minute period to trigger an alert, %.
sensitivity	string	Sensitivity of the threshold. With `low` sensitivity, high statistical confidence is used. Brief violations (for example, due to a surge in load) won't trigger alerts. With `high` sensitivity, no statistical confidence is used. Each violation triggers alert. The sensitivity element can hold these values.

Failure rate during any 5-minute period to trigger an alert, %.

sensitivity

string

Sensitivity of the threshold.

With low sensitivity, high statistical confidence is used. Brief violations (for example, due to a surge in load) won't trigger alerts.

With high sensitivity, no statistical confidence is used. Each violation triggers alert.

The sensitivity element can hold these values.

The FailureRateIncreaseAutodetectionConfig object

Parameters of failure rate increase auto-detection. Required if detectionMode is DETECT_AUTOMATICALLY. Not applicable otherwise.

The absolute and relative thresholds both must exceed to trigger an alert.

Example: If the expected error rate is 1.5%, and you set an absolute increase of 1%, and a relative increase of 50%, the thresholds will be: Absolute: 1.5% + 1% = 2.5% Relative: 1.5% + 1.5% * 50% = 2.25%

Element	Type	Description
failingServiceCallPercentageIncreaseAbsolute	integer	Absolute increase of failing service calls to trigger an alert, %.
failingServiceCallPercentageIncreaseRelative	integer	Relative increase of failing service calls to trigger an alert, %.

The LoadSpikeDetectionConfig object

The configuration of load spikes detection.

Element	Type	Description
enabled	boolean	The detection is enabled (`true`) or disabled (`false`).
loadSpikePercent	integer	Alert if the observed load is more than X % of the expected value.
minAbnormalStateDurationInMinutes	integer	Alert if the service stays in abnormal state for at least X minutes.

The LoadDropDetectionConfig object

The configuration of load drops detection.

Element	Type	Description
enabled	boolean	The detection is enabled (`true`) or disabled (`false`).
loadDropPercent	integer	Alert if the observed load is less than X % of the expected value.
minAbnormalStateDurationInMinutes	integer	Alert if the service stays in abnormal state for at least X minutes.

The ResponseTimeDegradationDetectionConfig object

Configuration of response time degradation detection.

Element	Type	Description
detectionMode	string	How to detect response time degradation: automatically, or based on fixed thresholds, or do not detect. The detectionMode element can hold these values.
automaticDetection	ResponseTimeDegradationAutodetectionConfig
thresholds	ResponseTimeDegradationThresholdConfig

The ResponseTimeDegradationThresholdConfig object

Fixed thresholds for response time degradation detection.

Required if detectionMode is DETECT_USING_FIXED_THRESHOLDS. Not applicable otherwise.

Element	Type	Description
responseTimeThresholdMilliseconds	integer	Response time during any 5-minute period to trigger an alert, in milliseconds.
slowestResponseTimeThresholdMilliseconds	integer	Response time of the 10% slowest during any 5-minute period to trigger an alert, in milliseconds.
loadThreshold	string	Minimal service load to detect response time degradation. Response time degradation of services with smaller load won't trigger alerts. The loadThreshold element can hold these values.
sensitivity	string	Sensitivity of the threshold. With `low` sensitivity, high statistical confidence is used. Brief violations (for example, due to a surge in load) won't trigger alerts. With `high` sensitivity, no statistical confidence is used. Each violation triggers an alert. The sensitivity element can hold these values.

The ResponseTimeDegradationAutodetectionConfig object

Parameters of the response time degradation auto-detection. Required if the detectionMode is DETECT_AUTOMATICALLY. Not applicable otherwise.

Violation of any criterion triggers an alert.

Element	Type	Description
responseTimeDegradationMilliseconds	integer	Alert if the response time degrades by more than X milliseconds.
responseTimeDegradationPercent	integer	Alert if the response time degrades by more than X %.
slowestResponseTimeDegradationMilliseconds	integer	Alert if the response time of the slowest 10% degrades by more than X milliseconds.
slowestResponseTimeDegradationPercent	integer	Alert if the response time of the slowest 10% degrades by more than X %.
loadThreshold	string	Minimal service load to detect response time degradation. Response time degradation of services with smaller load won't trigger alerts. The loadThreshold element can hold these values.

The ConfigurationMetadata object

Metadata useful for debugging

Element	Type	Description
configurationVersions	integer[]	A Sorted list of the version numbers of the configuration.
currentConfigurationVersions	string[]	A Sorted list of string version numbers of the configuration.
clusterVersion	string	Dynatrace server version.
