I have an incoming event (to a spring boot application)in json format that contains a field called "component". I need to create a metrics counter and push to prometheus pushgateway per-component. There should be individual counters for every type of component. How to achieve this?

You can use a hashmap for this. hashmap.put(component.name(), counter++) will solve it. – ozkanpakdil Feb 27 '20 at 12:33

How do you use prometheus pushgateway to implement a counter metric? What is the curl command? Thanks – Michael JDI Jun 23 '20 at 17:56

You can implement component for that. Autowire MeterRegistry
private MeterRegistry registry;
And put map of counters inside.
private Map<String, Counter> counters = new ConcurrentHashMap<>();
add method:
public void increment(String componentName){
Counter counter = counters.get(componentName);
if(counter == null) {
counter = Counter.builder("your.metrics.name").tags("component", componentName).register(registry);
counters.put(tagValue, counter);
}
counter.increment();
}
