What are Slow Lucene Operations?

Plumbr monitors Lucene indexes being used via instrumenting and monitoring all implementations of org.apache.lucene.search.IndexSearcher and org.apache.lucene.index.IndexWriter interfaces. Doing so allows Plumbr to track all the operations modifying the index or reading from the index. This support is implemented and tested on Lucene 4 and 5 releases.

By monitoring the behavior of said interfaces, Plumbr is capable of exposing:

• The impact poorly performing Lucene indexes have on your end users
• Actual root cause, down to a single line in source code accessing the index
• Information about the index accessed, including the index size, accessed fields, accessor methods and more.
