Review request for mesos, Alexander Rukletsov and Ben Mahler.


Used stringify instead of string::to_string.

Repository: mesos


Added benchmark test for the allocator metrics endpoint.

Diffs (updated)

  src/tests/hierarchical_allocator_tests.cpp 459e02576f6d05abbbcc83ae5cabac5c66e93f05 



The benchmark uses the same parametrized setup as other `HierarchicalAllocator_BENCHMARK_Tests`
which already elsewhere take considerable time. The reason for covering the same parameter
space here was the assumption that that parameter space does capture the relevant scenarios.

The benchmark shows that the time needed to obtain the metrics has a linear relationship with
the number of registered frameworks, roughly independent of the number of slaves. With my
setup, the time per framework was well below 1 ms after already a few frameworks.
