This database object in icinga2 for connecting database and fetch data. They use adapter but pdo is empty. Can A add here my pdo? Is it right with icniga2 framework?

ipl\Sql\Connection Object
(
    [config:protected] => ipl\Sql\Config Object
        (
            [db] => mysql
            [host] => localhost

            [charset] => utf8
            [options] => 
            [type] => db
            [persistent] => 0
        )

    [pdo:protected] => 
    [queryBuilder:protected] => 
    [adapter:protected] => ipl\Sql\Adapter\Mysql Object
        (
            [quoteCharacter:protected] => Array
                (
                    [0] => `

                    [17] => 
                )

        )

Answer 1

You can use PDO .

Very Nice article to get started with PDO.

1. How to connect to MySQL using PDO
2. Select query with PDO

$strQuery = "SELECT 
   `user`,
   COUNT(0) as Total_Count,
   MAX(range_count) Max_Range_Count
FROM (
   SELECT
       a.`user`, 
       a.change_time, 
       COUNT(0) range_count
   FROM audit_log a
   INNER JOIN audit_log b ON a.`user` = b.`user` 
   WHERE b.change_time BETWEEN a.change_time AND a.change_time + INTERVAL 30 MINUTE
   GROUP BY a.`user`, a.change_time
) AS user_range_count
GROUP BY `user`";

foreach ($conn->query($strQuery) as $row) {
    print_r($row);
}

First Install any database resource module in incinga like Icinga Web 2 - IPL it will help us to call pdo queries in incinga then you can check its documentation how to run any statement with binding parameter. example:

use ipl\Sql\Select;
use PDO;
$stmt = 'Select * from table where id=?';
$id=1;
$execute=$this->dbConnection->fetchAll($stmt,[$id]);
