Measures reported by SolrSearcherTest

The Searcher (or IndexSearcher) is the Solr internal backend component which performs the core function of indexing and searching. When the new documents or location are added to Solr, Solr searcher starts indexing and the documents are visible and are available for search only when the commit operation is completed. Since searcher is key to overall search efficiency of Solr, it is important for administrators that indexing is working at optimal levels and any issues are reported as soon as possible.

This test monitors the Solr Searcher and collects key metrics related to it's performance like number of documents indexed, commit size etc. These metrics provide valuable insights into searcher efficiency and allows administrators to take prompt action if its performance is below par.

Outputs of the test: One set of results for each Solr core in Apache Solr setup.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
numDocs Indicates the total number of documents indexed during the last measurement period. Number Ideally the value of this measure should be 0.
maxDocs Indicates the largest possible number of documents which can be handled by Solr Server. Number It depends on the current setup of Solr server, RAM availability, storage and compute capability.
indexCommitsize Indicates the size of last document index commit. MB Large commit size is preferable as it means a lot of documents will be available for search quickly.
deletedDocs Indicates the total number of documents deleted. Number
