This is a left aside module that wants to be released.

Write marks to watchdog or devel's query log at the beginning and end of each run stage of page execution.

This is a suite of three modules that compound a instrument to measure Drupal and help in identifying responsibles of time and memory consumption.

Modules implement hooks that just write marks to devel query log and/or the watchdog.

Additionally a set of patches are provided (see patches/*)) to enable measuring at some internal points where we can't hook and patching is the only option.

cd sites/all/modules
git clone https://github.com/jonhattan/drupal-sb_stagemarker.git
drush pm-enable sb_stagemarker, sb_stagemarker_before, sb_stagemarker_after

Configure devel module to display queries and display time and memory consumption.

Add this to settings.php at your convenience:

// Enable devel query log.
$conf['dev_query'] = 1;
$conf['devel_query_display'] = 1;
$conf['devel_query_sort'] = 0;

// Show time and memory consumption.

$conf['dev_mem'] = 1;
$conf['dev_timer'] = 1;

Additionally, if you plan to apply any of the available patches, add this to settings.php:

require_once 'sites/all/modules/sb_stagemarker/sb_stagemarker.module';

• Devel queries log.
• drush wd-show --tail

• Find the other versions I have of this module and push updates
• Find a nice name ('instrument'?)
• Publish to drupal.org
