Hi,

I have written an issue on [Kafka cluster cannot receive alerts · Issue #2017 · influxdata/kapacitor · GitHub](https://github.com/influxdata/kapacitor/issues/2017) with details

I wonder how to send alerts to kafka.  
kapacitor 1.5.1

stream  
|from()  
.measurement(‘win\_cpu’)  
|alert()  
.crit(lambda: “Percent\_Processor\_Time” \> 80)  
.message(‘Hey, check your CPU’)  
.kafka()  
.cluster(‘kafka01’)  
.kafkaTopic(‘cpu-alerts’)

Everything seems OK, but kafka cluster cannot receive messages from my kapacitor.
