Hi, I have just started exploring Splunk. My requirement is to capture metrics from the a set of micro services running in our environment. I see splunk provides multiple options for this. I am not clear which one is the right one to use. I see REST API exposed by Splunk with endpoints for both CollectD and StatsD line protocols. Also I see there is a Universal forwarder which needs to be installed in the different host machines and that will forward to splunk indexer. I feel installing a forwarder on all machines might be a constraint but might have better performance but, I am not sure how we can send metrics to Universal Forwarder. Is there a REST API for that. Also, there is an option to use TCP instead of HTTP. I am also not sure how I can send using TCP. Also, would TCP give better performance than HTTP. Can someone please guide me on the right approach for the right scenario? ... View more
