/debug/pprof/trace, runs a trace profile for 30 seconds/debug/pprof/profile, runs a pprof profile for 30 seconds/debug/pprof/heap, runs aheapmemory profile for 30 seconds
Only one prof will be allowed to run at any point, and requesting multiple will block until the previous has completed.
/expvar, routes directly to the expvar handler
/healthcheck, reports if the server is internally healthy. This is what should be used for health checking by an LB./deepcheck, reports the status of downstream services. This should not be used for system healthcheck, as a bad dependency should not cause an otherwise healthy server to cycle, because it will likely fail again.

/vN/rawand/vN/event, takes in protobuf formatted raw metrics. This endpoint is intended for gostatsd to gostatsd communication only, and thus not documented. This is to deter a service which may not bother to consolidate metrics, which would be detrimental to the health of the aggregation service. The version spoken by a forwarding instance is not configurable.The compatibility guarantee is:
- A bump of N will be a major bump of the service version
- A bump of N will retain support for N-1, dropping N-2 if present.
- A major bump of the service version may not increase N.
- A major bump of the service version may drop N-1 support without adding N+1.
- There will never be more than N-1 and N.
All changes of N will be documented in the CHANGELOG.md. N is currently 2.
