Accelerate Recovery:Intelligent Monitoring Framework (IMF) Registration, Blocking, Notification andRemediationIntelligent Monitoring Framework (IMF)– Agent registers resource with the AMFKernel Driver and provides it resourcespecific information– Agent blocks and awaits notificationon resource status change– Resource status changeinstantaneously relayed to theblocking agent for handlingHADAgent FrameworkAMF DriverFaulted Enable extremely fast failure detectionand remediation Significant reduction in system resourceutilization thus devoting key resources forother processingRegistering ResourcesIMF: Agents loosely coupled with resources, wait onthe AMF driver for notificationBulletproof Your Linux Environment6
