Response body objects

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.

ElementTypeDescription
metadataConfigurationMetadata

Metadata useful for debugging

responseTimeDegradationResponseTimeDegradationDetectionConfig

Configuration of response time degradation detection.

loadDropLoadDropDetectionConfig

The configuration of load drops detection.

loadSpikeLoadSpikeDetectionConfig

The configuration of load spikes detection.

failureRateIncreaseFailureRateIncreaseDetectionConfig

Configuration of failure rate increase detection.

The ConfigurationMetadata object

Metadata useful for debugging

ElementTypeDescription
configurationVersionsinteger[]

A sorted list of the version numbers of the configuration.

currentConfigurationVersionsstring[]

A sorted list of version numbers of the configuration.

clusterVersionstring

Dynatrace version.

The ResponseTimeDegradationDetectionConfig object

Configuration of response time degradation detection.

ElementTypeDescription
detectionModestring

How to detect response time degradation: automatically, or based on fixed thresholds, or do not detect.

The element can hold these values
  • DETECT_AUTOMATICALLY
  • DETECT_USING_FIXED_THRESHOLDS
  • DONT_DETECT
automaticDetectionResponseTimeDegradationAutodetectionConfig

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.

thresholdsResponseTimeDegradationThresholdConfig

Fixed thresholds for response time degradation detection.

Required if detectionMode is DETECT_USING_FIXED_THRESHOLDS. Not applicable otherwise.

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.

ElementTypeDescription
responseTimeDegradationMillisecondsinteger

Alert if the response time degrades beyond X milliseconds.

responseTimeDegradationPercentinteger

Alert if the response time degrades beyond X %.

slowestResponseTimeDegradationMillisecondsinteger

Alert if the response time of the slowest 10% degrades beyond X milliseconds.

slowestResponseTimeDegradationPercentinteger

Alert if the response time of the slowest 10% degrades beyond X %.

loadThresholdstring

Minimal service load to detect response time degradation.

Response time degradation of services with smaller load won't trigger alerts.

The element can hold these values
  • FIFTEEN_REQUESTS_PER_MINUTE
  • FIVE_REQUESTS_PER_MINUTE
  • ONE_REQUEST_PER_MINUTE
  • TEN_REQUESTS_PER_MINUTE

The ResponseTimeDegradationThresholdConfig object

Fixed thresholds for response time degradation detection.

Required if detectionMode is DETECT_USING_FIXED_THRESHOLDS. Not applicable otherwise.

ElementTypeDescription
responseTimeThresholdMillisecondsinteger

Response time during any 5-minute period to trigger an alert, in milliseconds.

slowestResponseTimeThresholdMillisecondsinteger

Response time of the 10% slowest during any 5-minute period to trigger an alert, in milliseconds.

loadThresholdstring

Minimal service load to detect response time degradation.

Response time degradation of services with smaller load won't trigger alerts.

The element can hold these values
  • FIFTEEN_REQUESTS_PER_MINUTE
  • FIVE_REQUESTS_PER_MINUTE
  • ONE_REQUEST_PER_MINUTE
  • TEN_REQUESTS_PER_MINUTE
sensitivitystring

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 element can hold these values
  • HIGH
  • LOW
  • MEDIUM

The LoadDropDetectionConfig object

The configuration of load drops detection.

ElementTypeDescription
enabledboolean

The detection is enabled (true) or disabled (false).

loadDropPercentinteger

Alert if the observed load is less than X % of the expected value.

minAbnormalStateDurationInMinutesinteger

Alert if the service stays in abnormal state for at least X minutes.

The LoadSpikeDetectionConfig object

The configuration of load spikes detection.

ElementTypeDescription
enabledboolean

The detection is enabled (true) or disabled (false).

loadSpikePercentinteger

Alert if the observed load is more than X % of the expected value.

minAbnormalStateDurationInMinutesinteger

Alert if the service stays in abnormal state for at least X minutes.

The FailureRateIncreaseDetectionConfig object

Configuration of failure rate increase detection.

ElementTypeDescription
detectionModestring

How to detect failure rate increase: automatically, or based on fixed thresholds, or do not detect.

The element can hold these values
  • DETECT_AUTOMATICALLY
  • DETECT_USING_FIXED_THRESHOLDS
  • DONT_DETECT
automaticDetectionFailureRateIncreaseAutodetectionConfig

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%

thresholdsFailureRateIncreaseThresholdConfig

Fixed thresholds for failure rate increase detection.

Required if detectionMode is DETECT_USING_FIXED_THRESHOLDS. Not applicable otherwise.

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%

ElementTypeDescription
failingServiceCallPercentageIncreaseAbsoluteinteger

Absolute increase of failing service calls to trigger an alert, %.

failingServiceCallPercentageIncreaseRelativeinteger

Relative increase of failing service calls to trigger an alert, %.

The FailureRateIncreaseThresholdConfig object
