VCS performance consideration when a resource goes offline

Similar to the online function, the offline function takes the resource offline and may return before the resource is actually offline. Subsequent monitoring confirms whether the resource is offline. The time it takes to offline a resource equals the time it takes for the resource to go offline, plus the duration of subsequent monitoring and reporting to VCS that the resource is offline. Most resources are typically offline when the offline function finishes. The agent schedules the monitor immediately after the offline function finishes, so the first monitor detects the resource as offline.
