Marvel Dashboard meaning

Hello everyone,

i was wondring what is the meaning of "search-request-rate" and "indexing-request-rate" graphs. Is it the rate that elasticsearch serves the requests or the rate of requests' arrival?


It's the rate the requests come in.
And (on a high level) unless your cluster has issues causing threadpool backups, it should also be the same rate that they are served.

To be precise, I think indexing rate is the rate at which ES serves reqeusts, ES doesn't keep track of the incoming requests I think (atleast in node stats). Node stats contain the stat "Total documents indexed" .
I guess marvel calculates the indexing rate by doing d(Documents Indexed)/d(Time Interval)
