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
