I’m have 3 queries (A, B, C) getting messages per second metrics from 3 nodes (node1, node2, node3). Then my query D, Id is total, Expression is node1+node2+node3, and Alias is TOTAL. Simply the addition of those metrics, and it graphs fine.
Although the legend shows the Id, not the Alias (not sure that matters)
I want to set an alert if the total messages is below a threshold. But when I create the alert on query D it always returns no_data. Any idea what I am doing wrong?
