-------------------------------------
Summary: Metrics page causing "HttpParser URI is too large >8192"
Key: SOLR-12814
URL: https://issues.apache.org/jira/browse/SOLR-12814
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: metrics, SolrCloud
Affects Versions: 7.5
Environment: 3x zookeeper and 3x solr cloud servers,
50 test collections with 0 data in them
Reporter: matthew medway
Attachments: longmetricsquery.txt
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}
After changing the header size log:
{code:java}
attached as a file because its very long and ugly{code}
Is it possible to break up this command into batches so that it can run without
modifying the header sizes?
Thanks!
