A method for managing a GRID network. The method includes performing trend analysis of a job type repeatedly processed by the GRID network to anticipate a future load on the GRID network associated with the job type. The job type is associated with a service level agreement (SLA). At least one internal performance metric of the GRID network is measured to monitor current GRID network status. The future load that is anticipated is compared with the at least one performance metric to predict future satisfaction of the SLA.
