Bigger installations (>200k services) tend to have a large WATO configuration with thousands of folders and hosts. Finding a host in these configuration took a considerable amount of time on some pages

  • Web API host calls, except add_host
  • Bulk discovery
  • Host diagnose
  • Fetching agent output
  • Service discovery
  • And some other pages, where the actual folder of the host is not known/specified

To fix this problem, a folder lookup index has been introduced to improve the time taken to find a hostname in the configuration.
