The Scenario

There are certain SQL Agent Jobs that are scheduled to run every few minutes throughout the day.

There are legitimate times when it

    /**** FOR CURRENTLY RUNNING JOBS ****/
    SELECT j.name AS Job_Name,DATEDIFF(ss,a.start_execution_date ,GETDATE ())   
    FROM msdb.dbo.sysjobactivity a INNER JOIN msdb.dbo.sysjobs j 
    ON a.job_id =j.job_id
    WHERE CONVERT(DATE,a.start_execution_date )=CONVERT(DATE,GETDATE ())
    AND a.stop_execution_date IS NULL
    
    
    /*This code will give u the Name of currently running jobs and for how much time it is running & after that u can add filters to it as u wish*/
    /*Thanks in advance*/

    This solution would work:

    SELECT DATEDIFF(SECOND,aj.start_execution_date,GetDate()) AS Seconds
    FROM msdb..sysjobactivity aj
    JOIN msdb..sysjobs sj on sj.job_id = aj.job_id
    WHERE aj.stop_execution_date IS NULL -- job hasn't stopped running
    AND aj.start_execution_date IS NOT NULL -- job is currently running
    AND sj.name = 'JobX'
    and not exists( -- make sure this is the most recent run
        select 1
        from msdb..sysjobactivity new
        where new.job_id = aj.job_id
        and new.start_execution_date > aj.start_execution_date
    )
    

    This a more general check dependent on system tables. If you'd prefer a custom route, you could have the job insert into a job log table you created instead.

    What you're doing manually sounds like what's known as a "watch dog loop". Basically, an SQL job that starts and/or monitors agent jobs, killing them if need be.

    The code below was taken from here, and should help, removing the need for you to manually monitor and kill jobs if they've been running for a lengthy period of time:

    /****************************************************************
    --This SQL will take a list of SQL Agent jobs (names must match),
    --start them so they're all running together, and then
    --monitor them, not quitting until all jobs have completed.
    --
    --In essence, it's an SQL "watchdog" loop to start and monitor SQL Agent Jobs
    --
    --Code from http://cc.davelozinski.com/code/sql-watchdog-loop-start-monitor-sql-agent-jobs

    --Should be in hh:mm:ss format. 
    DECLARE @WaitDelay VARCHAR(8) = '00:00:20'
    
    --Job timeout. Eg, if the jobs are running longer than this, kill them.
    DECLARE @TimeoutMinutes INT = 240

    --Insert the names of the SQL jobs here. Last two values should always be NULL at this point.
    --Names need to match exactly, so best to copy/paste from the SQL Server Agent job name.
