MSSQL – check that the Agent Job have been run as Schedule

I have this problems, that if a schedule inside a Agent job, have not been started for some reason, there will be no errors about this problem.

So Í have created this script, that will give the Status of 1, if the job, haven’t been run for the last two hours.
I used PRTG to check the status.

USE msdb
GO

DECLARE @JobName VARCHAR(1000)
DECLARE @LastRunTime VARCHAR(1000)
DECLARE @LastRunStatus VARCHAR(1000)
DECLARE @CurrentTime VARCHAR(20)

SET @JobName = 'JOBNAME'

SET @CurrentTime = LEFT(REPLACE(CONVERT (time, DATEADD(HOUR, - 2, GETDATE())),':',''),6)

SELECT DISTINCT @LastRunTime = SJH.run_time
FROM sysjobhistory SJH, sysjobs SJ
WHERE SJ.[name] = @JobName AND SJH.job_id = SJ.job_id and SJH.run_date = 
(SELECT MAX(SJH1.run_date) FROM sysjobhistory SJH1 WHERE SJH.job_id = SJH1.job_id)

IF @LastRunTime >= @CurrentTime
	SELECT '0' AS Status
 ELSE
	SELECT '1' AS Status

In line 10, replace – 2 with the number of hours, you want to go back

Below is the same script, just for daily jobs, so it will will check if the job haven’t been run in the last 25 hours (My Schedule is set to run every 24 hours, and i give it an hour to be finish, before i got an alarm.

DECLARE @JobName VARCHAR(1000)
DECLARE @LastRunDate VARCHAR(1000)
DECLARE @LastRunStatus VARCHAR(1000)
DECLARE @CurrentDate VARCHAR(20) -- used for file name

SET @JobName = 'JOBNAME'

SET @CurrentDate = REPLACE(CONVERT (date, DATEADD(HOUR, -25, GETDATE())),'-','') 

SELECT DISTINCT @LastRunDate = SJH.run_date
FROM sysjobhistory SJH, sysjobs SJ
WHERE SJ.[name] = 'Fibia optimering daglig (Batch 2)' AND SJH.job_id = SJ.job_id and SJH.run_date = 
(SELECT MAX(SJH1.run_date) FROM sysjobhistory SJH1 WHERE SJH.job_id = SJH1.job_id)
ORDER BY SJH.run_date desc

IF @LastRunDate >= @CurrentDate
	SELECT '0' as Status
 ELSE
 	SELECT '1' as Status

In line 10, replace – 25 with the number of hours, you want to go back

Implement SQL Server Agent Jobs with AlwaysOn Availability Groups

The function I use fn_hadr_group_is_primary from this post is a UDF (User Defined Function) that we create in the master database. The function gets an Availability Group name as an input parameter and returns a Boolean value indicating weather this instance is a primary replica.

-- fn_hadr_group_is_primary
USE master;
GO
IF OBJECT_ID('dbo.fn_hadr_group_is_primary', 'FN') IS NOT NULL
  DROP FUNCTION dbo.fn_hadr_group_is_primary;
GO
CREATE FUNCTION dbo.fn_hadr_group_is_primary (@AGName sysname)
RETURNS bit
AS
BEGIN;
  DECLARE @PrimaryReplica sysname; 

  SELECT
    @PrimaryReplica = hags.primary_replica
  FROM sys.dm_hadr_availability_group_states hags
  INNER JOIN sys.availability_groups ag ON ag.group_id = hags.group_id
  WHERE ag.name = @AGName;

  IF UPPER(@PrimaryReplica) =  UPPER(@@SERVERNAME)
    RETURN 1; -- primary

    RETURN 0; -- not primary
END; 

Use the fn_hadr_group_is_primary function within a new job step to find if this sql instance is a Primary replica. If this is not a primary replica we issue a stop job request while identifying the current job name using SQL Server Agent Tokens

-- Detect if this instance's role is a Primary Replica.
-- If this instance's role is NOT a Primary Replica stop the job so that it does not go on to the next job step
DECLARE @rc int; 
EXEC @rc = master.dbo.fn_hadr_group_is_primary N'my-ag';

IF @rc = 0
BEGIN;
    DECLARE @name sysname;
    SELECT  @name = (SELECT name FROM msdb.dbo.sysjobs WHERE job_id = CONVERT(uniqueidentifier, '$(ESCAPE_NONE(JOBID))'));
    
    EXEC msdb.dbo.sp_stop_job @job_name = @name;
    PRINT 'Stopped the job since this is not a Primary Replica';
END;

Add Exchange management Shell to “normal powershell

Here are a script, that you can include in yours script, to add Exchange management shell, to “normal” powershell scripts.

$StopWatch = [System.Diagnostics.StopWatch]::StartNew()
Function Test-Command ($Command)
{
    Try
    {
        Get-command $command -ErrorAction Stop
        Return $True
    }
    Catch [System.SystemException]
    {
        Return $False
    }
}

IF (Test-Command "Get-Mailbox") {Write-Host "Exchange cmdlets already present"}
Else {

    $CallEMS = ". '$env:ExchangeInstallPath\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto -ClientApplication:ManagementShell "

    Invoke-Expression $CallEMS
$stopwatch.Stop()
$msg = "`n`nThe script took $([math]::round($($StopWatch.Elapsed.TotalSeconds),2)) seconds to execute..."
Write-Host $msg
$msg = $null
$StopWatch = $null
}
