Hi, I'm brand new to Splunk coming from a background using Prometheus metrics. I've been reading through Splunk docs but I'm struggling to get some of the basics down. I was looking at https://docs.splunk.com/Documentation/Splunk/8.1.1/Metrics/GetMetricsInOther which talks about HTTP/JSON but is this saying my application would offer an HTTP endpoint for polling/pulling, or my application needs to call an endpoint on the Splunk server? I've always worked using the poll paradigm before and one thing I can't seem to find are examples of how to instrument metrics in my own code. In particular, 90% of our system (which comprises dozens of modules) is written in C++ and I would really love to see a code example of instrumenting and exposing a metric (e.g. number of calls to MyMethod() in C++, for consumption by Splunk Enterprise. Many thanks for any help.
