> If you have a lot of collections, like 50 or more, the new metrics page in
> version 7.5 can't run its queries because the default
> solr.jetty.request.header.size and solr.jetty.response.header.size values are
> too small.
> If I up the header values from 8192 to 65536 the commands will work.
> command to change the defaults:
> {code:java}
> sed -i 's/\"solr.jetty.request.header.size\"
> default=\"8192\"/\"solr.jetty.request.header.size\" default=\"65536\"/g'
> /opt/solr/server/etc/jetty.xml
> sed -i 's/\"solr.jetty.response.header.size\"
> default=\"8192\"/\"solr.jetty.response.header.size\" default=\"65536\"/g'
> /opt/solr/server/etc/jetty.xml
> {code}
> before changing the header size log:
> {code:java}
