How to get current value from Prometheus using Grok Exporter

[Akila Jayasinghe]

I have a Grok exporter gauge metric which returning API response time in a audit log file. I'm using grafana dashboard to visualize Prometheus values.

Problem is Prometheus holding last value of metric until a new value come for it. Think if  "XXX" API's response time is 5 second on 08:33 time and when 08:34 time "XXX" API not called again. But Prometheus still holding his last value until getting a new value. My requirement is, only return current values of the API. (Only return called API response time.) 

I need a solution to clear this issue. Please kindly assist.
