lib/vmselectapi: limit the number of concurrently executed requests
This should prevent from out of memory errors when big number of vmselect
nodes send many concurrent requests to vmstorage

The limit can be controlled at vmstorage via the following command-line flags:
- search.maxConcurrentRequests
- search.maxQueueDuration

vmselect performs the following tasks:

  • Splits incoming selects to tasks for vmstorage nodes and issues these tasks to all the vmstorage nodes in the cluster.

  • Merges responses from all the vmstorage nodes and returns a single response.

The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
