Hi all,
I’m pretty new to Grafana and I’ve been stuck on this problem for a while now.
I have an alert rule that sends an email alert to a contact point when the “oneminavg” of a CPU slot passes a certain threshold
Purpose: to print all values of the CPU slots from the queries and send them to the email notification.
I have 5 similar queries for the 5 slots of CPU :
I also have reduce expressions for each of the queries
And finally I used a math and a Threshold expression to combine all the reduce expressions
I have also tried where the math formula is :
$F > 0 || $G > 0 || $H > 0 || $I > 0 || $J > 0 || or ($F > 0) || ($G > 0) || ($H > 0) || ($I > 0) || ($J > 0) ||
This is the annotations that I used to send the email notification to test whether all values are printed or not :
But in the end it always results as :
in the email notification.
and in the math expression, it says that “Expression Warning: 4 items dropped from union(s)”
Can anyone explain?
Help is much appreciated!!
