Hi Shawn, Thanks for replying to my questions. So is it correct to assume that exposing merge metrics is not known to cause any performance degradation? -suresh On Wed, Jan 10, 2018 at 5:40 PM, Shawn Heisey wrote: > On 1/10/2018 11:08 AM, S G wrote: > >> Last comment by

Re: regarding exposing merge metrics

Thanks Shalin for sharing the link. However if I follow the thread then it seems like there was no conclusive evidence found that the performance degradation was due to the merge or index related metrics. If that is the case then can we just get rid of the config and publish these metrics by

Re: regarding exposing merge metrics

The merge metrics were enabled by default in 6.4 but they were turned off in 6.4.2 because of large performance degradations. For more details, see https://issues.apache.org/jira/browse/SOLR-10130 On Tue, Jan 9, 2018 at 9:11 AM, S G wrote: > Yes, this is actually

Re: regarding exposing merge metrics

Yes, this is actually confusing and the documentation ( https://lucene.apache.org/solr/guide/7_2/metrics-reporting.html) does not help either: *Index Merge Metrics* : These metrics are collected in respective registries for each core (e.g., solr.core.collection1…​.), under the INDEX category.
