Example using Pushgateway and Prometheus
Boot the contianers:
docker-compose up -d
Seed prometheus, by pushing metrics to pushgateway, so that prometheus can scrape pushgateway:
bash write.sh
Access prometheus:
open http://localhost:9090/graph?g0.expr=heartrate&g0.tab=0&g0.stacked=0&g0.show_exemplars=0&g0.range_input=15m
