Hello !
I’ve just begun with Kapacitor, InfluxDB and Telegraf. I’m trying to implement all little tasks presented in the InfluxData Getting Started (see that link: https://docs.influxdata.com/kapacitor/v1/introduction/getting-started/).
Everything is ok until the Trigger Alert from Stream data paragraph. I followed the instructions but I got the following error message:
“. expected: “number”,“string”,“duration”,“identifier”,“TRUE”,“FALSE”,”==“,”(“,”-“,”!"1 in "stream
Here is my command:
kapacitor define cpu_alert -type stream -tick cpu_alert.tick -dbrp kapacitor_example.autogen
Here is my cpu_alert.tick:
stream
|from()
.measurement(‘cpu’)
|alert()
.crit(lambda: “usage_idle” < 70)
.log(‘/tmp/alerts.log’)
Finally here is my kapacitor.conf (following the instructions I found on the website):

I found the

_kapacitor = [“autogen”]
strange and I removed it but it didn’t change anything.
Thanks for your help!
