Closed gitrepocc closed 3 years ago

gitrepocc commented 3 years ago

Hello, I am new to express and node js. can you please tell me whether these requests made to /metrics endpoint asynchronous or synchronous?

which requests?

There is no POST, there is no push. Prometheus server PULLs the metrics by itself using GET. All the library does is it provides this /metrics endpoint for Prometheus. The library doesn't do any requests at all.

See prometheus docs for details: https://prometheus.io/docs/introduction/overview/

POST requests that push metrics to prometheus server from my app. The middleware code, promBundle();
