How to find aborted connection day wise

 How to find aborted connection day wise

One important metric to monitor is the aborted connection ration,which indicated number of faild connectionsattempts relative to the total number of connection attempts.


Step.1.Now we are going to create table.

CREATE TABLE `daily_aborted_connections` (

`id` INT(11) NOT NULL AUTO_INCREMENT,

`log_date` DATE NULL DEFAULT NULL,

`aborted_connection_total` INT(11) NULL DEFAULT NULL,

`aborted_connection_yesterday` INT(11) NULL DEFAULT NULL,

`aborted_connection_today` INT(11) NULL DEFAULT NULL,

`connection_total` INT(11) NULL DEFAULT NULL,

`connection_yesterday` INT(11) NULL DEFAULT NULL,

`connection_today` INT(11) NULL DEFAULT NULL,

`aborted_connections_ration_daywise` DECIMAL(10,2) NULL DEFAULT NULL,

`log_inserted_time` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,

`log_time_ist` DATETIME NULL DEFAULT CURRENT_TIMESTAMP,

PRIMARY KEY (`id`) USING BTREE

)

COLLATE='latin1_swedish_ci'

ENGINE=InnoDB

AUTO_INCREMENT=9

;

Step.2.Now we are going to create store procedure .

CREATE DEFINER=`db_user`@`%` PROCEDURE `log_aborted_connection`()

LANGUAGE SQL

NOT DETERMINISTIC

CONTAINS SQL

SQL SECURITY DEFINER

COMMENT ''

BEGIN


DECLARE current_aborted_connections INT;

DECLARE previous_aborted_connections INT DEFAULT 0;

DECLARE daily_aborted_connectionss INT;

DECLARE aboted_connection_yesterday INT DEFAULT 0;


DECLARE current_connection INT;

DECLARE previous_connections INT DEFAULT 0;

DECLARE daily_connections INT;

DECLARE connection_yesterday INT DEFAULT 0;

DECLARE connection_today INT;


####GET the CURRENT aborrted connections.


SELECT variable_value INTO current_aborted_connections FROM performance_schema.global_status WHERE variable_name='aborted_connects';


##get the total aborted connection from the privioud day.

SELECT SUM(aborted_connection_today) INTO previous_aborted_connections FROM daily_aborted_connections;


##calculate the daily aborted connections.

SET daily_aborted_connectionss=current_aborted_connections-IFNULL(previous_aborted_connections,0);

SET previous_aborted_connections=(SELECT aborted_connection_today FROM daily_aborted_connections ORDER BY id DESC LIMIT 1);


##get the current total connection

SELECT variable_value INTO current_connection FROM performance_schema.global_status WHERE variable_name='connections';


###get the total connection from the previous day.

SELECT SUM(connection_today) INTO previous_connections FROM daily_aborted_connections;


##calculate the daily connection

SET daily_connections=current_connection-IFNULL(previous_connections,0);

SET connection_yesterday=(SELECT connection_today FROM daily_aborted_connections ORDER BY id DESC LIMIT 1);


##insert the daily aborted connections and connected into the table.

##INSERT INTO daily_aborted_connections(log_date)

INSERT INTO `daily_aborted_connections` (log_date, aborted_connection_total, aborted_connection_yesterday,aborted_connection_today,connection_total,connection_yesterday,connection_today, aborted_connections_ration_daywise)

VALUES(NOW(),current_aborted_connections,IFNULL(aboted_connection_yesterday,0),daily_aborted_connectionss,current_connection,IFNULL(connection_yesterday,0),daily_connections,

((daily_aborted_connectionss/daily_connections)*100));

END


Step.3.show sample output

 MySQL Point in Time Recovery: How To Configure And How Does it Work? The point-in-time recovery allows you to restore a MySQL database to a specific time in the past. The point-in-time recovery relies on two key components: Full backup: This serves as the foundation for recovery, providing the starting state of the database. Binary logs: These binary log files record all changes made to the database, allowing you to replay those changes to a desired point. If you don’t have a full backup or binary logs enabled, you cannot carry the point-in-time recovery. We’ll illustrate how to perform the point-in-time recovery in MySQL to recover a database to a specific point in time. Checking binar log status:- We need login to mysql server and run given below command:- show global variables like 'log_bin' ; Show output for enable mysql-bin log. Creating a new sample database & taking a full backup:- We are going to login in mysql databse and creating new database and table.given ...

 MySQL Replication Switchover: Step-by-Step Guide MySQL replication is a powerful feature that allows you to create redundant copies of your database for improved availability and scalability. In certain scenarios, it becomes necessary to switch the roles of the master and slave servers in a replication setup. This article will guide you through the process of performing a MySQL replication switchover, ensuring a smooth transition without any data loss. Let’s dive into the step-by-step instructions. I have tow node one is master node and another is slave node.Given below details:- Current Master: 192.168.70.10 Current Slave : 192.168.70.11 Verifying the Replication:- Before initiating the switchover, it’s important to verify that replication is functioning correctly on the current Slave server (192.168.70.11). Execute the following queries to ensure the replication status: mysql> show slave status\G This command displays the slave’s status, including information such as replicat...

Mysql Commercial Mysqlbackup:How to take Differential or Incremental Backup and resotre using mysqlbackup utility in mysql 8.0.37 enterprise edition Incremental vs Differential Backup:- The main difference between incremental and differential backups is how they save space and time by storing only changed files. However, the effectiveness of incremental backups is very different from differential backups. Before we dive into the differences between Incremental and Differential backups let’s review Full Backups.  Are you still using Full Backups? In its simplest form, a full backup is the starting point for both Incremental and Differential backup strategies. A full backup, of course, backs up all the data on a partition or disk by copying all disk sectors with data to the backup image file.  A full backup is time-consuming and requires a lot of space, it’s usually used as part of a backup plan with long intervals, like once a week or a month. During this time, if anything goes...
