expose extra statistics like slow queries
------------------------------------------
Key: SOLR-1101
URL: https://issues.apache.org/jira/browse/SOLR-1101
Project: Solr
Issue Type: New Feature
Components: web gui
Reporter: Noble Paul
Fix For: 1.5
Solr Objects may want to expose extra information for diagnostics etc. These
information can be large and we may not wish to show it in the stats page which
can make it unwieldly. I propose an extension of the stats itself which can be
shown separately.
I wish to implement slow queries as a part of this. There is a new interface
which can be implemented by components
{code:java}
public interface StatsDetails {
public interface StatsDetails {
/**The details info is a Map of details name versus description. The details
name must
* return the details when the getDetails() method is invoked on the same
object.
* @return a map of details name vs the description. the description may be
used in a link text
*/
public Map<String ,String> getDetailsInfo();
/**The details key should be known for this Object .
* This key will may be obj=tained by invoking getDetailsInfo()
*
* @param detailsCommand
* @return
*/
public NamedList getDetails(String detailsCommand);
}
{code}
The stats.jsp can be enhanced to show these extra links .
