Hi, I am following the instructions from https://lucene.apache.org/solr/guide/7_1/metrics-reporting.html in order to expose the Index merge related metrics.
The document says that we have to add the below snippet in order to expose the merge metrics <config> ... <indexConfig> <metrics> <majorMergeDocs>524288</majorMergeDocs> <bool name="mergeDetails">true</bool> </metrics> ... </indexConfig> ...</config> I would like to know why is this metrics not exposed by default just like all the other metrics? Is there any performance overhead that we should be concerned about it? If there was no particular reason, then can we expose it by default? Regards Suresh
