When the value of query_result_sys_network_track_error is empty, the result is also empty. I want it to default to 0, regardless of whether the minuend or subtrahend is empty. I tried using vector(0), but when used together with sum by, the same problem occurs. My current query is: ``` (sum by (host)(sum_over_time(query_result_sys_network_track_error[24h]))) - (sum by (host)(sum_over_time(query_result_sys_network_track_error[24h] offset 7d))) ``` I tried using vector(0) to solve this problem but it did not work: ``` (sum by (host)(sum_over_time(query_result_sys_network_track_error)) or vector(0)) - (sum by (host)(sum_over_time(query_result_sys_network_track_error[24h] offset 7d)) or vector(0)) ``` -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
