Count missing data for metric with label

[Yaron B]

Hello, I have a metric that checks the lag of a consumer group.

 from time to time, the metric is missing for a specific label, as shown in the image attached.

I would like to get a graph that counts whenever there is a missing data point.

for example , for the image attached I would like to get 0 until 

6:50,

then 1 until 7:50, 0 again until 8:05, and then 1 until 8:58

is there a way to write a query to this metric to get the graph that I need?

thanks!

ok got it, ignore the dollar sign, its from grafana

count(sum(kafka_consumergroup_lag{consumergroup="$consumergroup"}) by (consumergroup)) -1 or on() vector(1)
