UpdateLogAnomalyDetector

Updates an existing log anomaly detector.

Request Syntax

{ "anomalyDetectorArn": "string", "anomalyVisibilityTime": number, "enabled": boolean, "evaluationFrequency": "string", "filterPattern": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

anomalyDetectorArn

The ARN of the anomaly detector that you want to update.

Type: String

Length Constraints: Minimum length of 1.

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

Required: Yes

anomalyVisibilityTime

The number of days to use as the life cycle of anomalies. After this time, anomalies are automatically baselined and the anomaly detector model will treat new occurrences of similar event as normal. Therefore, if you do not correct the cause of an anomaly during this time, it will be considered normal going forward and will not be detected.

Type: Long

Valid Range: Minimum value of 7. Maximum value of 90.

Required: No

enabled

Use this parameter to pause or restart the anomaly detector.

Type: Boolean

Required: Yes

evaluationFrequency

Specifies how often the anomaly detector runs and look for anomalies. Set this value according to the frequency that the log group receives new logs. For example, if the log group receives new log events every 10 minutes, then setting evaluationFrequency to FIFTEEN_MIN might be appropriate.

Type: String

Valid Values: ONE_MIN | FIVE_MIN | TEN_MIN | FIFTEEN_MIN | THIRTY_MIN | ONE_HOUR

Required: No

filterPattern

A symbolic description of how CloudWatch Logs should interpret the data in each log event. For example, a log event can contain timestamps, IP addresses, strings, and so on. You use the filter pattern to specify what to look for in the log event message.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 1024.

Required: No
