Google Cloud 日志记录，仅针对新出现的错误发送 Slack 通知

Question

need to send alerts to slack using google cloud logging but send the alert only once, because the alert may be repeated multiple times and this will cause a lot of miss.

Answer 1

I think to resolve your issue, in addition to the filter for the log based metric , you should add labels with extractors.

The metric is checked for each labels and not once.

In my example I added a log based metric with a filter for some error types in Cloud Composer . In order to increment my metric and make be unique, I also added labels on the current Airflow task id and execution date .

Then I just need to create an alerting policy on this log based metric with a treshold.

If I don't add labels and extractor, my alert is fired only once.
