Hmm. I am doing the same thing. But, somehow in my browser, after I select the core, it does not stay selected to view the stats/cache. Attaching the gif for when I try it.
Anyway, that is a different issue from my side. Thanks for your input. -Lewin -----Original Message----- From: Shawn Heisey <apa...@elyograg.org> Sent: Tuesday, April 9, 2019 1:52 PM To: solr-user@lucene.apache.org Subject: Re: Solr Cache clear On 4/9/2019 12:38 PM, Lewin Joy (TMNA) wrote: > I just tried to go to the location you have specified.

It will only show up when you select a *core* from the other dropdown. In SolrCloud, collections are made up of one or more shards. Shards are made up of one or more replicas. Every shard replica is a core. Here are some partial screenshots showing what I clicked on to get to the cache stats: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.dropbox.com_s_ked4xe4w45e9qr2_cache-2D1.png-3Fdl-3D0&d=DwICaQ&c=DDPRwrN9uYSNUDpKqPeD1g&r=WMeiuwk_Qf7aOundlWmtZMlairjO8ZQxQpAndx7JD6A&m=9o8kD9YOypvijGkYVvikg-74p2wDw2kblxyrVUijnaI&s=Zr1cZF633BlxWx0semmI-DCywSyOteEEM9_eABk-OrM&e= https://urldefense.proofpoint.com/v2/url?u=https-3A__www.dropbox.com_s_7v630mr2ii0rtee_cache-2D2.png-3Fdl-3D0&d=DwICaQ&c=DDPRwrN9uYSNUDpKqPeD1g&r=WMeiuwk_Qf7aOundlWmtZMlairjO8ZQxQpAndx7JD6A&m=9o8kD9YOypvijGkYVvikg-74p2wDw2kblxyrVUijnaI&s=rCCFdR6yk2ElhXMyxX0LJJoPkymG8Y3rrxCQz3gK8fI&e= https://urldefense.proofpoint.com/v2/url?u=https-3A__www.dropbox.com_s_6czqtxq5qf8vzwz_cache-2D3.png-3Fdl-3D0&d=DwICaQ&c=DDPRwrN9uYSNUDpKqPeD1g&r=WMeiuwk_Qf7aOundlWmtZMlairjO8ZQxQpAndx7JD6A&m=9o8kD9YOypvijGkYVvikg-74p2wDw2kblxyrVUijnaI&s=sA5FxVsaP1M8bGkxUnGdVoW7nLjF7rFthVCG6sKY_po&e= The system where I captured these screenshots was not running in SolrCloud mode, so it did not have the "collections" dropdown that your admin UI will have. When you reload a collection, Solr uses the information in ZooKeeper to locate all of the shard replicas that make up the collection, and reloads all those cores. So a collection reload is basically equivalent to multiple core reloads. Thanks, Shawn
