基于输入遥测数据的 azure 流分析警报

Question

How can we send an alert message to table storage if one of the telemetry inputs is greater than the threshold set in Reference JSON? How would one convert threshold will comparison to "Alert output"?

Answer 1

for this you need to define the telemetry input as stream, and the threshold input as reference data. You can use either blob storage or SQL for reference data Then do a reference data JOIN as specified here: https://docs.microsoft.com/en-us/stream-analytics-query/reference-data-join-azure-stream-analytics Let me know if you have any further question.

假设您的参考 JSON 存储在 SQL 中，您可以使用 GetArrayElements 来转换参考数据。可能这与您正在尝试的最接近，但在这里我使用 SQL 数据库作为参考而不是 blob 存储。
