The Query Stats plugin tracks database queries.
Use the “queries” helper or controller method to access data on the queries. See the documentation on QueryStats::Holder for functionality.
You can easily display statistics in your page footer, such as:
Queries in Controller: <%= queries.count_with_label :controller %> Queries in View: <%= queries.count_with_label :view %> Query Time: <%= queries.runtime %>
QueryStats adds the number of queries to the log in the DB section:
Completed in 0.00642 (155 reqs/sec) | Rendering: 0.00228 (35%) | DB: 0.00247 (38%) 6 queries | 200 OK [http://test.host/]
X-QueryCount will be set to the number of queries
X-QueryRuntime will be set to the db runtime
Tests pass with:
Rails: 1.2.6, 2.0.2, 2.1.0
Adapters: sqlite3, mysql
