Anomaly - Amazon CloudWatch Logs

Anomaly

This structure represents one anomaly that has been found by a logs anomaly detector.

For more information about patterns and anomalies, see CreateLogAnomalyDetector.

Contents

active

Specifies whether this anomaly is still ongoing.

Type: Boolean

Required: Yes

anomalyDetectorArn

The ARN of the anomaly detector that identified this anomaly.

Type: String

Length Constraints: Minimum length of 1.

Pattern: [\w#+=/:,.@-]*

Required: Yes

anomalyId

The unique ID that CloudWatch Logs assigned to this anomaly.

Type: String

Length Constraints: Fixed length of 36.

Required: Yes

description

A human-readable description of the anomaly. This description is generated by CloudWatch Logs.

Type: String

Length Constraints: Minimum length of 1.

Required: Yes

firstSeen

The date and time when the anomaly detector first saw this anomaly. It is specified as epoch time, which is the number of seconds since January 1, 1970, 00:00:00 UTC.

Type: Long

Valid Range: Minimum value of 0.

Required: Yes

histogram

A map showing times when the anomaly detector ran, and the number of occurrences of this anomaly that were detected at each of those runs. The times are specified in epoch time, which is the number of seconds since January 1, 1970, 00:00:00 UTC.

Type: String to long map

Key Length Constraints: Minimum length of 1.

Required: Yes

lastSeen

The date and time when the anomaly detector most recently saw this anomaly. It is specified as epoch time, which is the number of seconds since January 1, 1970, 00:00:00 UTC.

Type: Long

Valid Range: Minimum value of 0.

Required: Yes

logGroupArnList

An array of ARNS of the log groups that contained log events considered to be part of this anomaly.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 2048.

Pattern: [\w#+=/:,.@-]*

Required: Yes

logSamples

An array of sample log event messages that are considered to be part of this anomaly.

Type: Array of LogEvent objects

Required: Yes

patternId

The ID of the pattern used to help identify this anomaly.

Type: String

Length Constraints: Fixed length of 32.

Required: Yes

patternString

The pattern used to help identify this anomaly, in string format.

Type: String

Length Constraints: Minimum length of 1.

Required: Yes

patternTokens

An array of structures where each structure contains information about one token that makes up the pattern.

Type: Array of PatternToken objects

Required: Yes

state

Indicates the current state of this anomaly. If it is still being treated as an anomaly, the value is Active. If you have suppressed this anomaly by using the UpdateAnomaly operation, the value is Suppressed. If this behavior is now considered to be normal, the value is Baseline.

Type: String

Valid Values: Active | Suppressed | Baseline

Required: Yes

isPatternLevelSuppression

If this anomaly is suppressed, this field is true if the suppression is because the pattern is suppressed. If false, then only this particular anomaly is suppressed.

Type: Boolean

Required: No

patternRegex

The pattern used to help identify this anomaly, in regular expression format.

Type: String

Length Constraints: Minimum length of 1.

Required: No

priority

The priority level of this anomaly, as determined by CloudWatch Logs. Priority is computed based on log severity labels such as FATAL and ERROR and the amount of deviation from the baseline. Possible values are HIGH, MEDIUM, and LOW.

Type: String

Length Constraints: Minimum length of 1.

Required: No

suppressed

Indicates whether this anomaly is currently suppressed. To suppress an anomaly, use UpdateAnomaly.

Type: Boolean

Required: No

suppressedDate

If the anomaly is suppressed, this indicates when it was suppressed.

Type: Long

Valid Range: Minimum value of 0.

Required: No

suppressedUntil

If the anomaly is suppressed, this indicates when the suppression will end. If this value is 0, the anomaly was suppressed with no expiration, with the INFINITE value.

Type: Long

Valid Range: Minimum value of 0.

Required: No
