/spanio, /spanblock, /spansched, /spansyscall provide the pprof-style summary of span execution's io, block, scheduling, syscall latency distributions respectively. The computation logic for /io, /block, /sched, /syscall analysis was refactored and extended for reuse in these new types of analysis. Upon the analysis query, we create a map of goroutine id to time intervals based on the query parameter, that represents the interesting time intervals of matching goroutines. Only the events from the matching goroutines that fall into the intervals are considered in the pprof computation. The new endpoints are not yet hooked into other span analysis page (e.g. /userspan) yet.
