Hi, We have found that application teams often fire ad-hoc queries, some of these are very expensive queries and can bring the solr cluster down. Some times they just build custom scripts which does some offline analytics by firing expensive queries, the solr cluster was originally not sized for executing such queries.
When an issue happens we identify from the solr logs the query which is taking long time. But some times we do not even know who is firing these queries and hence it takes a while to stop them. We would like be able to identify the source of the solr queries. Is there a way to tag the solr queries? Can we associate some tags or query identifier with the query? These tags should be made mandatory without which the solr query should fail? We would like to build a custom component which logs the query, the query identifier (the tag which user provides) and the IP address of the client machine which fired this query. Thanks Suresh
