Javier Jaramago Fernández	100630fba5	Second iteration on PostgreSQL monitoring POC This commit packs multiple fixes/improvements: - Added READONLY support for PostgreSQL. - Major rework for queries and statements used on monitoring checks: + Checks/Actions rewrote for single instance checks. + Reuse of prepared statements instance of re-preparation. - Fixed missing error handling in connection creation state machine. - Fixed connection rotation in connection pool (now FIFO). - Added support for configurable batching in scheduler thread, via '_interval_window' variables. These variables allows to define the burstiness of the scheduling within the processing interval. - Added new config variable 'pgsql-monitor_dbname'. Allows to control which 'db' will be target by monitoring connections. - Several fixes for 'poll' timeout computation for worker threads. - Fixed edge cases for current interval detection. - Reduced deviation in scheduling intervals computation. - Refactored and simplified connection event handling. - Improved error messages for monitoring actions. - Replaced several invalid uses of 'mysql_thread___monitor_' in favor or new 'mysql_thread___monitor_*' variables. - Honor '-M' argument for disabling monitoring support.	2 years ago

Second iteration on PostgreSQL monitoring POC

This commit packs multiple fixes/improvements:

- Added READONLY support for PostgreSQL.
- Major rework for queries and statements used on monitoring checks:
    + Checks/Actions rewrote for single instance checks.
    + Reuse of prepared statements instance of re-preparation.
- Fixed missing error handling in connection creation state machine.
- Fixed connection rotation in connection pool (now FIFO).
- Added support for configurable batching in scheduler thread, via
  '*_interval_window' variables. These variables allows to define the
  burstiness of the scheduling within the processing interval.
- Added new config variable 'pgsql-monitor_dbname'. Allows to control
  which 'db' will be target by monitoring connections.
- Several fixes for 'poll' timeout computation for worker threads.
- Fixed edge cases for current interval detection.
- Reduced deviation in scheduling intervals computation.
- Refactored and simplified connection event handling.
- Improved error messages for monitoring actions.
- Replaced several invalid uses of 'mysql_thread___monitor_*' in
  favor or new 'mysql_thread___monitor_*' variables.
- Honor '-M' argument for disabling monitoring support.
