---------------------------------------
[~DineshkumarK] were you able to find a fix for this. ? We are running
Solrcloud 7.5.0 and facing the same issue. Metrics endpoint is taking too long
to respond.
The Solr admin page displays "connection to Solr lost" due to this.
> Timeout Issue with Solr Metrics API

> Hi Team,
> We are facing a "Connection to Solr lost" error on the Solr admin page. While
> debugging, we found an issue with the admin/metrics API.
> *Detail Analysis:*
> We have around 200+ collections on a Solr cloud cluster which is having 4
> Solr nodes among which 3 are zookeeper+Solr nodes. Whenever we try to hit the
> "cloud" page on the Solr admin UI it results in a "Connection to Solr lost"
> error within few seconds.
> When we tried to debug the same, we found Solr admin/metrics API that is
> called internally is taking *20K ms* and leads to time out which results in
> Connection to Solr lost error. On the other hand, we tried to hit the same
> query separately on a browser which still takes *20K ms* but we get a proper
> response.
> When the admin/metrics API call is happening from the admin console, the
> first call is taking a long time and finally fails to load the response. As a
> result, *concurrent multiple calls were made for the same API* and throws
> "Connection to Solr lost"
> We tried a few ways to disable this API call and to increase the timeout, but
> nothing works.
> We could see the AdminHandlerProxy timeout warning in Solr logs. Attached the
> error msg from Solr logs.
