How do you monitor and troubleshoot SQL Server Agent job performance and failures across an entire server with many scheduled jobs?

You can query the msdb system database's job history tables directly, such as sysjobhistory, to build custom reports showing job success rates, average duration, and failure trends over time, which is especially useful on a server with many jobs where manually checking each one individually through the graphical interface would be impractical.

SELECT j.name, h.run_date, h.run_status, h.run_duration
FROM msdb.dbo.sysjobs j
JOIN msdb.dbo.sysjobhistory h ON j.job_id = h.job_id
WHERE h.step_id = 0
ORDER BY h.run_date DESC;
