dbrp “ABC”.“autogen”

var data = stream  
|from()  
.database(“ABC”)  
.retentionPolicy(“autogen”)  
.measurement(memoryUtil)  
.groupBy(host)  
|window()  
.period(1m)  
.every(1m)  
.align()  
|median(‘available\_percent’)  
.as(‘value’)

data  
|alert()  
.warn(lambda: “value” \< warn)  
.crit(lambda: “value” \< crit)  
.stateChangesOnly()  
.message(message)  
.topic(topic)

Let assume at a particular time My data is:

name: memoryUtil  
tags: host=ip-111-111-17-208  
time median

time median

Question: When I set my critical to less that 30%, I am getting only one alert instead of two. How to get alerts for both the hosts.  
e.g. .crit(lambda: “value” \< 30)

Because one of them is 34%, which is greater than 30%. If the samples you provided are real

1528787490000000000 _34.31948838933012_

name: memoryUtil  
tags: host=ip-111-111-53-24  
time median

1528787510000000000 19.15578168915138

name: memoryUtil  
tags: host=ip-111-111-84-49  
time median

So only one will alert. What was the threshold before?

@philb

I set my critical alert to less that 30 e.g. crit(lambda: “value” \< 30). So two machines ip-111-111-53-24 and ip-111-111-84-49 should be generating critical alerts but I get only one.

Sorry i misread your first post.

Have the machines gone into the OK state since generating the first alert? You could try removing the stateChangesOnly and increasing the threshold so they recover - then change the thresholds back.
