How the Sybase and SybaseBk agents support intelligent resource monitoring
With intelligent monitoring framework (IMF), VCS supports intelligent resource monitoring in addition to the poll-based monitoring. Poll-based monitoring polls the resources periodically whereas intelligent monitoring performs asynchronous monitoring.
You can enable or disable the intelligent resource monitoring functionality of the VCS agents for Sybase and SybaseBk using haimfconfig script or manually.
See Enabling and disabling intelligent resource monitoring (IMF) for agents.
When an IMF-enabled agent starts up, the agent initializes the asynchronous monitoring framework (AMF) kernel driver. After the resource is in a steady state, the agent registers the details that are required to monitor the resource with the AMF kernel driver. For example, the Sybase agent registers the PIDs of the processes with the AMF kernel driver. The agent's imf_getnotification function waits for any resource state changes. When the AMFkernel driver module notifies the imf_getnotification function about a resource state change, the agent framework runs the monitor agent function to ascertain the state of that resource. The agent notifies the state change to VCS which takes the appropriate action.
