Statistics
Table of Contents
 
  MySQL Native Driver contains support for gathering statistics on the
  communication between the client and the server. The statistics
  gathered are of two main types:
  
   - 
    Client statistics
   
- 
    Connection statistics
   
  When using the mysqli extension,
  these statistics can be obtained through two API calls:
  
   - 
    mysqli_get_client_stats
   
- 
    mysqli_get_connection_stats
   
Note: 
  
   Statistics are aggregated among all extensions that use the MySQL Native
   Driver.
   For example, if the mysqli
   extension and the PDO MySQL driver are both set-up to use MySQLnd,
   then function calls from mysqli
   and method calls from PDO will affect the statistics.
  
  
   There is no way to find out how much a certain API call of any extension
   that has been compiled against MySQL Native Driver has impacted a certain
   statistic.
