How to determine MySQL queries per day?

For SELECTs:

show global status like "Com_select";

UPDATEs:

show global status like "Com_update";

INSERTs: 

show global status like "Com_insert";

DELETEs:

show global status like "Com_delete";

ALl values are "cumulativ" since MySQL last restart.

So to get your SELECTs in one hour:

At 9pm:

[21:00:00] [DEV\(none)] mysql> show global status like "Com_select";
+---------------+--------+
| Variable_name | Value  |
+---------------+--------+
| Com_select    | 671664 |
+---------------+--------+
1 row in set (0.00 sec)

At 10pm:

[22:00:00] [DEV\(none)] mysql> show global status like "Com_select";
+---------------+--------+
| Variable_name | Value  |
+---------------+--------+
| Com_select    | 672363 |
+---------------+--------+
1 row in set (0.00 sec)

The number of SELECT in the past hour : 672363 - 671664 = 699

Best Regards


I use this view to keep an eye on the number of queries per second, minute, hour and day:

create or replace view _dba_query_stats as
select 
  SUBSTRING(VARIABLE_NAME, 5) as query_type, 
  VARIABLE_VALUE as total_count, 
  round(VARIABLE_VALUE / ( select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status'), 2) as per_second,
  round(VARIABLE_VALUE / ((select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status') / (60)))       as per_minute,
  round(VARIABLE_VALUE / ((select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status') / (60*60)))    as per_hour, 
  round(VARIABLE_VALUE / ((select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status') / (60*60*24))) as per_day,
  FROM_UNIXTIME(round(UNIX_TIMESTAMP(sysdate()) - (select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status'))) report_period_start,
  sysdate() as report_period_end,
  TIME_FORMAT(SEC_TO_TIME((select VARIABLE_VALUE from information_schema.GLOBAL_STATUS where VARIABLE_NAME = 'Uptime_since_flush_status')),'%Hh %im') as report_period_duration
from 
  information_schema.GLOBAL_STATUS 
where 
  VARIABLE_NAME in ('Com_select', 'Com_delete', 'Com_update', 'Com_insert');

Sample output:

query_type total_count per_second per_minute per_hour per_day report_period_start report_period_end   report_period_duration
