Kapacitor - convert value from decimal to percentage

InfluxDB 1 Kapacitor

Hello,

I’m having trouble converting a value from a decimal (formatted like 0.35) to a percentage (formatted like 35). It works when I set the crit = 0.5

dbrp "telegraf"."autogen"
var db = 'telegraf'
var rp = 'autogen'
var measurement = 'mesos'
var groupBy = ['datacenter']
var whereFilter = lambda: TRUE
var period = 10s
var every = 30s
var name = 'Mesos Slave Pool CPU'
var idVar = name + '-{{.Group}}'
var message = 'Mesos CPU pool low on `{{ index .Tags "datacenter" }}` (Current value: {{ index .Fields "value" }})'
var idTag = 'alertID'
var levelTag = 'level'
var messageField = 'message'
var durationField = 'duration'
var outputDB = 'chronograf'
var outputRP = 'autogen'
var outputMeasurement = 'alerts'
var triggerType = 'threshold'
var crit = 0.5

var data = stream
    |from()
        .database(db)
        .retentionPolicy(rp)
        .measurement(measurement)
        .groupBy(groupBy)
        .where(whereFilter)
    |window()
        .period(period)
        .every(every)
        .align()
    |last('master/cpus_percent')
        .as('value')

var trigger = data
    |alert()
        .crit(lambda: "value" > crit)
        .stateChangesOnly()
        .message(message)
        .id(idVar)
        .idTag(idTag)
        .levelTag(levelTag)
        .messageField(messageField)
        .durationField(durationField)
        .slack()
        .workspace('myworkspace')
        .channel('@me')

trigger
    |eval(lambda: float("value"))
        .as('value')
        .keep()
    |influxDBOut()
        .create()
        .database(outputDB)
        .retentionPolicy(outputRP)
        .measurement(outputMeasurement)
        .tag('alertName', name)
        .tag('triggerType', triggerType)

trigger
    |httpOut('output')

However, I’d really like to be able to set crit = 50 and convert the value to a whole number. I have tried setting it in the data portion

    |eval(lambda: last('master/cpus_percent') * 100)
        .as('value')

as well as the trigger portion, but it doesn’t work

trigger
    |eval(lambda: float("value") * 100)
        .as('value')
        .keep()
    |influxDBOut()

Is this possible? Cheers

Hi ,

the trigger should be
trigger
|eval(lambda: float(“value”) * 100.0)
.as(‘value’)
.keep()
|influxDBOut()
