# Invalid Tick script

#1

Hi,

I have this TICK script but i couldn’t find the error. I have added some [[httppost]] to the kapacitor.config for endpoint “onoff”

``````batch
|query('SELECT mean(usage_idle) as usage_idle FROM "telegraf"."autogen".cpu')
.period(5m)
.every(1m)
|influxDBOut()
.database('telegraf')
.retentionPolicy('autogen')
.measurement('cpu_idle_1hour')
.precision('s')
.info(lambda: "usage_idle" > 80)
.warn(lambda: "usage_idle" > 90)
.crit(lambda: "usage_idle" > 95)
.post()
.endpoint('onoff')``````

You can use “kapacitor show < task name >” to see the output from the task itself. I tend to do that, then tail my kapacitor logs for the taskname so i can see when it runs.

Have you tried swapping the |influxDBOut and |Alert nodes around?

``````|alert()
.info(lambda: "usage_idle" > 80)
.warn(lambda: "usage_idle" > 90)
.crit(lambda: "usage_idle" > 95)
.post()
.endpoint('onoff')

|influxDBOut()
.database('telegraf')
.retentionPolicy('autogen')
.measurement('cpu_idle_1hour')
.precision('s')
``````

Also, i think you have a typo. Should you be specifying .httpPost(), instead of .post()?

``````|alert()
.info(lambda: "usage_idle" > 80)
.warn(lambda: "usage_idle" > 90)
.crit(lambda: "usage_idle" > 95)
.httpPost()
.endpoint('onoff')
``````

Thanks @philb ,

I was trying different permutations and combinations yesterday and it worked when i moved the alert above the influxDBOut. But Unfortunately, i couldn’t figure out the reason behind and hence kept the question opened.

Thanks for sharing tips for debugging.
