drupal measure author's publication efficiensy drupal 7 - performance

Question

I have made a drupal 7 site.
I'm looking for a solution for measuring the authors (blog writers, article writers) efficiensy.
I would like to see someweher, how many nodes are created by a user (author) per month and how many letters do these nodes contain.
Can you suggest me a modul or something else?
Thanks,
Tamás

Here is my solution:
<?php
/**
* Implements hook_menu().
*/
function authors_efficiency_menu() {
$items = array();
$items['admin/config/authors_efficiency'] = array(
'title' => 'Own Settings',
'description' => 'Parent item',
'position' => 'left',
'weight' => -100,
'page callback' => 'system_admin_menu_block_page',
'page arguments' => array(),
'access arguments' => array('access administration pages'),
'file' => 'system.admin.inc',
'file path' => drupal_get_path('module', 'system'),
);
// Need at least one child item before your section will appear.
$items['admin/config/authors_efficiency/efficiency'] = array(
'title' => 'Authors efficiency',
'description' => 'Authors efficiency',
'page callback' => 'authors_efficiency_page_callback',
'page arguments' => array(),
'access arguments' => array('access administration pages'),
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function authors_efficiency_page_callback($para=array()){
$output= '';
// define number of results per page
$num_per_page = 50;
$header = array('User','Month','Count','Length sum','Avarage length');
// define sql to fetch results
$query= db_select('node','n');
$query->condition('n.status', '1');
$query->condition('n.created', (time()-(120*24*60*60)), '>');
$query->join('field_data_body', 'b', 'n.nid = b.entity_id');
$query->join('users', 'u', 'n.uid = u.uid');
$query->condition('b.entity_type', 'node');
$query->addExpression('CONCAT(YEAR(FROM_UNIXTIME(n.created)),\'-\',LPAD(MONTH(FROM_UNIXTIME(n.created)), 2, \'0\'))', 'node_month');
$query->addExpression('SUM(CHAR_LENGTH(b.body_value))', 'node_char_length');
$query->addExpression('COUNT(*)', 'node_count');
$query->fields('n', array('uid'));
$query->fields('u', array('name'));
$query->groupBy('CONCAT(n.uid, \'#\', node_month)');
$query->orderBy('node_month', 'DESC');
$query->orderBy('u.name', 'ASC');
$count_query= db_select('node','n');
$count_query->condition('n.status', '1');
$count_query->condition('n.created', (time()-(120*24*60*60)), '>');
$count_query->addExpression('COUNT(*)', 'node_count');
$count_query->fields('n', array('uid'));
$count_query->groupBy('CONCAT(n.uid, \'#\', CONCAT(YEAR(FROM_UNIXTIME(n.created)),\'-\',LPAD(MONTH(FROM_UNIXTIME(n.created)), 2, \'0\')))');
$count_query = $count_query->countQuery();
$maxCount = $count_query->execute()->fetchField();;
$page = pager_default_initialize($maxCount, $num_per_page);
$offset = $num_per_page * $page;
$query->range($offset, $num_per_page);
$result= $query->execute()->fetchAll();
$rows = array();
foreach($result as $record){
$row = array(
$record->name,
$record->node_month,
$record->node_count,
$record->node_char_length,
round($record->node_char_length/$record->node_count),
);
$rows[] = $row;
}
// Depending on the context there may be a better choice than this
$output.= theme('table', array('header' => $header, 'rows' => $rows));
$output.= theme('pager');
return($output);
}
?>
