collective.catalogtrace

Log details about ZCatalog query performance

Features

Logs details about each ZCatalog query:

• Query parameters
• Where the query was called
• Detailed execution:
  • Index name
  • Elapsed time
  • Count of persistent objects loaded
  • Count of new objects tracked by the Python GC

This information can be used to troubleshoot poor query performance.

There is some overhead to recording these measures.

Tracing is enabled for all queries if the TRACE_CATALOG_QUERIES environment variable is set.

Tracing can be enabled for specific requests by setting the catalogtrace cookie.
