Hi,
@nathaniel Thanks very much.
I find out some issues when use the mean function or sum funciton, alert is ok,
but the trigger events output to influxdb may loss some tags.
My tick script:
stream
|from()
.database('monitor')
.measurement('system_memory')
.where(lambda: "host" == 'dev1' AND "type_instance" == 'memory.used')
|window()
.period(1m)
.every(1m)
|mean('value')
.as('value')
|window()
.period(2m)
.every(2m)
|alert()
.id('{{index .Tags "host"}}.{{index .Tags "instance"}}')
.message('{{.TaskName}}')
.crit(lambda: "value" >= float(4200))
.all()
.levelTag('level')
.stateChangesOnly()
.log('/tmp/memoty-alert.log')
|influxDBOut()
.database('monitor')
.measurement('triggers_system')
.tag('id', 'memory-used-too-high')
Influxdb data:(use mean function)(I want get tags, e.g. 'type_instance',
'unit', 'host' .etc)
time host
id level type_instance unit
value
2016-09-23T08:46:30Z memory-used-too-high
CRITICAL 6134.3671875
2016-09-23T08:44:30Z memory-used-too-high
CRITICAL 6131.887890625
When I use max function: (the data in Influxdb are OK)
time host
id level type_instance unit
value
2016-09-23T09:03:40Z dev1 memory-used-too-high
CRITICAL memory.used MB 6123.87109375
2016-09-23T09:02:40Z dev1 memory-used-too-high
CRITICAL memory.used MB 6136.53125
[NOTE]: function of sum also have this issue.
Did I do something wrong??

Three consecutive times means for 6 minutes total so:
stream
|from()
.measurement('m')
|window()
.period(2m)
.every(2m)
|max('value')
|window()
.period(6m)
.every(6m)
|alert()
.crit(lambda: "max" >= threshold)
// mark that all points need to match the criteria
// in order to trigger the alert.
.all()

I have a scenario like the next:
Evaluate the max value every 2 minutes, if the max value greater than a
threshold three consecutive times, alert will be triggered.
How can I write the tick script?
Thanks!

All data that is within the time now - period will be emitted into the
pipeline. This means data can be emitted more than once if the period is longer
than every.

Hi all,
I have some confusions when I use kapacitor window node,
1. the every property define how ofen the data is emitted into the pipeline.
But, I want to know whether all data during the time will be emitted into
the pipeline, or is it just a data will be emitted into the pipeline.
Thanks!
