Hi,
I have the following :
Kapacitor, v1.1.1
InfluxDB, v 1.1.1
Telegraf, v1.1.2
I am having a little bit of trouble with the |last() function. (Or maybe my
understanding of it)
My TICK script gets loaded into Kapacitor with out any error.
After some time the "kapacitor show tasks" command lists the task as
"Executing:false".
I guess this is when the task has its first match on the incoming data
stream.
I have this in my TICK script :
----------------
var window = 1m
var every = 1m
var data = stream
|from()
.measurement('system')
.groupBy('host')
|window()
.period(window)
.every(every)
|last('uptime')
.as('last_uptime')
----------------
"system" is my measurement in InfluxDB.
"host" is a tag value in InfluxDB.
"uptime" is a field("integer") in InflxuDB.
I use the following to mach :
----------------
var crit = lambda: "last_uptime" < 300
var critReset = lambda: "last_uptime" >= 300
----------------
If I remove the "|Last()" function than the TICK scrip stays enabled, but
gives the wrong outcome.
IE; I get alerts for all points when "uptime" is from 0 to 300.
I just want to match on the last value.
Thanks for your help
Brendan
