Class IndexingStatsManager

java.lang.Object

com.atlassian.jira.issue.index.IndexingStatsManager

public class IndexingStatsManager
extends Object

Responsible for printing to log (periodically, on re-index) indexing statistics.

What can I do with this log?

Run: `grep indexing-stats atlassian-jira.log`

You should see following log messages:

• [indexing-stats] Top 10 addIndex total... - periodic log message shows top 10 most expensive (in therms of indexing/addIndex) fields since last re-index or system start
• [indexing-stats] Top 10 addIndex snapshot... - periodic log message shows top 10 most expensive (in therms of indexing/addIndex) fields since previous snapshot stats
• [indexing-stats] field indexing cost: {order:.. - after full-reindex log message shows all fields indexing cost (in therms of indexing/addIndex)

In general this log is showing you the cost of loading the data (from DB) to index.

See also MonitoringIndexWriter for [lucene-stats] log, which is showing the "lucene" side cost of indexing.
