- Dashboard loading on 400 node clusters takes forever.
- Investigation shows that the culprit is the following API call:

{code}
- Among the requested metrics FLUME_HANDLER is on all hosts and this API calls results in requesting all metrics on all hosts for Flume.
- Request is to remove the following from the requested properties: _"host_components/metrics/flume/flume"_. This results in API call returning in 2-3 seconds.
- It is required to analyze impact of this change from UI side and making the change.
