[Question] Is it possible to support streaming monitoring?

### Question

Thank you very much for providing such an easy-to-use monitoring system. I would like to ask a question about the usage we encountered ourselves. Thank you!

Our system service triggers alerts when logging keywords like XXXException. However, at this moment, the data is in the Kafka stream. I would like to trigger alerts directly upon encountering these keywords, that is, instantaneous alerts instead of a continuous increase in metrics. Is there a way to achieve this?

Start by reviewing HertzBeat's Kafka integration and alerting entry points to determine whether log streams can be consumed as alert events rather than metric updates. The issue provides no file or test names; done would require a confirmed supported configuration or a clearly scoped design for streaming keyword alerts.
