要获取AWS设备农场中设备的使用洞察,可以使用AWS IoT Core和AWS IoT Analytics服务。以下是一个解决方案的示例代码:
步骤1:设置AWS IoT Core规则 首先,您需要设置一个AWS IoT Core规则,以将设备数据发送到AWS IoT Analytics。
import boto3
iot_client = boto3.client('iot')
# 创建AWS IoT规则
def create_iot_rule():
rule_name = 'deviceFarmInsightsRule'
topic_rule_payload = {
'sql': "SELECT * FROM 'devices/#'",
'actions': [{
'iotAnalytics': {
'channelArn': 'YOUR_IOT_ANALYTICS_CHANNEL_ARN',
'roleArn': 'YOUR_IOT_ANALYTICS_ROLE_ARN'
}
}]
}
response = iot_client.create_topic_rule(
ruleName=rule_name,
topicRulePayload=topic_rule_payload
)
print(response)
create_iot_rule()
步骤2:设置AWS IoT Analytics管道和数据集 接下来,您需要设置AWS IoT Analytics管道和数据集来存储设备数据并生成使用洞察。
import boto3
iot_analytics = boto3.client('iotanalytics')
# 创建AWS IoT Analytics管道
def create_iot_analytics_pipeline():
pipeline_name = 'deviceFarmInsightsPipeline'
pipeline_activities = [
{
'channel': {
'name': 'deviceFarmInsightsChannel',
'channelName': 'deviceFarmInsightsChannel',
'channelStorage': {
'serviceManagedS3': {}
},
'retentionPeriod': {
'unlimited': True
}
}
},
{
'lambda': {
'name': 'deviceFarmInsightsLambda',
'lambdaName': 'deviceFarmInsightsLambda'
}
},
{
'datastore': {
'name': 'deviceFarmInsightsDatastore',
'datastoreName': 'deviceFarmInsightsDatastore'
}
},
{
'dataset': {
'name': 'deviceFarmInsightsDataset',
'actions': [
{
'actionName': 'deviceFarmInsightsDatastore',
'queryAction': {
'filters': [
{
'deltaTime': {
'offsetSeconds': 0,
'timeExpression': 'NOW()'
}
}
],
'sqlQuery': 'SELECT * FROM "deviceFarmInsightsDatastore" LIMIT 100'
}
}
]
}
},
{
'channel': {
'name': 'deviceFarmInsightsOutputChannel',
'channelName': 'deviceFarmInsightsOutputChannel',
'channelStorage': {
'serviceManagedS3': {}
},
'retentionPeriod': {
'unlimited': True
}
}
}
]
response = iot_analytics.create_pipeline(
pipelineName=pipeline_name,
pipelineActivities=pipeline_activities
)
print(response)
# 创建AWS IoT Analytics数据集
def create_iot_analytics_dataset():
dataset_name = 'deviceFarmInsightsDataset'
dataset_actions = [
{
'actionName': 'deviceFarmInsightsPipeline',
'queryAction': {
'filters': [
{
'deltaTime': {
'offsetSeconds': 0,
'timeExpression': 'NOW()'
}
}
],
'sqlQuery': 'SELECT * FROM "deviceFarmInsightsPipeline" LIMIT 100'
}
}
]
response = iot_analytics.create_dataset(
datasetName=dataset_name,
actions=dataset_actions
)
print(response)
create_iot_analytics_pipeline()
create_iot_analytics_dataset()
步骤3:获取设备使用洞察 最后,您可以使用AWS IoT Analytics查询设备使用洞察。
import boto3
iot_analytics = boto3.client('iotanalytics')
def get_device_insights():
dataset_name = 'deviceFarmInsightsDataset'
response = iot_analytics.get_dataset_content(datasetName=dataset_name)
print(response)
get_device_insights()
请注意,以上代码示例中的“YOUR_IOT_ANALYTICS_CHANNEL_ARN”和“YOUR_IOT_ANALYTICS_ROLE_ARN”需要替换为您自己的ARN。此外,您需要确保已正确设置AWS IoT Core和AWS IoT Analytics,并具有适当的权限来执行这些操作。
