hi all
I have written the following tick script
stream
|from()
.database('tech')
.retentionPolicy('autogen')
.measurement('passenger_queue')
|log()
|eval(
lambda: if("host" == '172.30.2.198','true','false')
)
.as('val')
|alert()
.id('kapacitor passenger_queues alert')
.message('{{ .Level }} {{ .ID }} /{{ index .Tags "host" }} has a
queue length :{{ index .Fields "value" }}')
.info(lambda: "value" > 50)
.warn(lambda: "value" > 70)
.crit(lambda: "value" > 80)
.stateChangesOnly()
.email()
|log()
on enbaling the script I get the following results in kapacitor show I GET
THE FOLLOWING RESULT :
DOT:
digraph pass_alert {
graph [throughput="0.00 points/s"];
stream0 [avg_exec_time_ns="0" ];
stream0 -> from1 [processed="160"];
from1 [avg_exec_time_ns="2.856µs" ];
from1 -> log2 [processed="160"];
log2 [avg_exec_time_ns="0" ];
log2 -> eval3 [processed="160"];
eval3 [avg_exec_time_ns="550.728µs" eval_errors="0" ];
eval3 -> alert4 [processed="160"];
alert4 [alerts_triggered="0" avg_exec_time_ns="101.577µs"
crits_triggered="0" infos_triggered="0" oks_triggered="0"
warns_triggered="0" ];
alert4 -> log5 [processed="0"];
log5 [avg_exec_time_ns="0" ];
}
THE PROBLEM IS THAT alerts_triggered are coming 0 while avg exec time is
non zero
as soon I as I remove the eval statement aleerts triggered start coming
