// Creates an anomaly detector that regularly scans one or more log groups and
// look for patterns and anomalies in the logs. An anomaly detector can help
// surface issues by automatically discovering anomalies in your log event traffic.
// An anomaly detector uses machine learning algorithms to scan log events and find
// patterns. A pattern is a shared text structure that recurs among your log
// fields. Patterns provide a useful tool for analyzing large sets of logs because
// a large number of log events can often be compressed into a few patterns. The
// anomaly detector uses pattern recognition to find anomalies , which are unusual
// log events. It uses the evaluationFrequency to compare current log events and
// patterns with trained baselines. Fields within a pattern are called tokens.
// Fields that vary within a pattern, such as a request ID or timestamp, are
// referred to as dynamic tokens and represented by <> . The following is an
// example of a pattern: [INFO] Request time: < > ms This pattern represents log
// events like [INFO] Request time: 327 ms and other similar log events that
// differ only by the number, in this csse 327. When the pattern is displayed, the
// different numbers are replaced by <*> Any parts of log events that are masked
// as sensitive data are not scanned for anomalies. For more information about
// masking sensitive data, see Help protect sensitive log data with masking (https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/mask-sensitive-log-data.html)
