[Question] Deserialize metrics from the file

[zavodnyuk]

Hi, in my app I don't use any kind of DB, but I want to serialize metrics to the file using getMetricsAsJSON every minute or after each event. Then in case I need to release a new version or restart my app I want read data from the file and continue count metrics. I found that I can use registerMetric and pass instance of Counter/Gauge/etc class but not the data from the file right away. Any elegant way I can de-serialize data on restart? Or the only option I have is read from the file, loop through the data and create instances and push them to registerMetric?
Thank you

There's indeed no way to do this current, and it sounds out of scope. Does pushGateway + using rates instead of absolute counts address your use case?

I decided to revamp my app and to add db as well. So no longer a case, thank you
