I expect that

```
	|window()
		.period(60s)
		.everyCount(3)

```

would emit data every three points. But I get output on every incoming point.  
What am I missing?

```
dbrp "snmp_trap"."default"

stream
        |from()
                .measurement('snmp_trap')
        |where(lambda: "name" == 'netSnmpExampleHeartbeatNotification')
        |window()
                .period(1m)
                .everyCount(3)
        |alert()
                .info(lambda: TRUE)
                .log('/tmp/chronic.log')
```

@nekrassov,  
Hmm that’s odd. I don’t know. But I’m not a Kapacitor export. I’ll pass your question on. Thank you.

Have you tried aligning the points?
