> API does not return metrics at the host component level (except for one host).
> STR.
> Make a metrics API against various hosts for a specific metric.
> Example on a 3-node cluster:
> Call 1:
> http://172.22.89.227:8080/api/v1/clusters/c1/hosts/sid-ams-3.novalocal/host_components/DATANODE?fields=metrics/load/load_five[1453147641,1453169241,15]
> This returns the metrics on sid-ams-3.
> Call 2:
> http://172.22.89.227:8080/api/v1/clusters/c1/hosts/sid-ams-2.novalocal/host_components/DATANODE?fields=metrics/load/load_five[1453147641,1453169241,15]
> This returns no metrics data.
> Call 3:
> http://172.22.89.227:8080/api/v1/clusters/c1/hosts/sid-ams-1.novalocal/host_components/DATANODE?fields=metrics/load/load_five[1453147641,1453169241,15]
> This returns no metrics data.
> The example above is for a system metric, but the same behavior is exhibited
> for service metrics.
> For any given host component metric, only one of the hosts returns any
> metric. The *first host that you make a query against* will return the
> metrics data, but none of the other hosts.
> This is because of the cache implementation.
