> Using API for metrics management developed in SOLR-4735 we should also start collecting metrics for major aspects of {{IndexWriter}} operation, such as read / write IO rates, number of minor and major merges and IO during these operations, etc.
> This will provide a better insight into resource consumption and load at the IO level.
