General You can configure the SQL Server Agent service to restart if the SQL Server service stops unexpectedly or if the SQL Server Agent service restarts unexpectedly You can also configure where to locate the error logs Advanced If you have a central SQL Server collecting all events, event forwarding can be configured on this page Also, the idle CPU condition is defined here Note that the idle CPU condition is not defined by default
NOTE The idle CPU condition deserves a special note since jobs can be configured to run when the CPU is idle, but will never run if this setting is not defined If you select the check box to Define Idle CPU Condition, by default it defines the CPU as idle if the CPU usage falls below 10 percent for more than 600 seconds (10 minutes) Both the percentage and the timing can be modified if desired
Alert System Use this page to configure mail session information, pager emails, and the fail-safe operator Job System A shutdown time-out interval (how long SQL gives a job to finish before forcibly shutting it down) and a global proxy account can be configured on this page Connection An alias local host server can be configured here History The size of history logs (in rows) can be configured here Additionally, SQL Server Agent can be configured to remove old logs automatically
