How to ignore empty dataseries in prometheus
12,433
I didn't try this one with NaN
, but you can simply filter by values with binary operators. Since NaN
mathematically doesn't equal NaN
you could try this trick (since a response time should be always positive):
avg(http_response_time{job=~"^(x|y)$",...} >= 0)

Calculating the maximum quantile over all dataseries is a problem for me:
query
http_response_time{job=~"^(x|y)$", quantile="0.95",...}
result
http_response_time{job="x",...} 0.26 http_response_time{job="y",...} NaN
This is how I would try to calculate the maximum:
avg(http_response_time{job=~"^(x|y)$",...})
Now the result will be "NaN". How can I ignore the "NaN" result (from the result section)?
UPDATE 0
The metric is a self made summary-metric.
UPDATE 1
Using prometheus version 1.8.
