rule={
'samplingConfig': {
'samplingPercentage': 123.0
},
'filters': [
{
'key': 'string',
'operator': 'Equals'|'NotEquals'|'GreaterThan'|'LessThan'|'GreaterThanOrEqual'|'LessThanOrEqual'|'Contains'|'NotContains',
'value': {
'stringValue': 'string',
'doubleValue': 123.0,
'booleanValue': True|False
}
},
],
'sessionConfig': {
'sessionTimeoutMinutes': 123
}
},
dataSourceConfig={
'cloudWatchLogs': {
'logGroupNames': [
'string',
],
'serviceNames': [

}
},
evaluators=[
{
'evaluatorId': 'string'
},
