If monitoring is to be used as a form of heartbeat, the preferred method is to call lbmmon_sctl_sample() from a context thread or event queue timer callback. This ensures that the object actually processing the messages is the one generating the monitoring statistics, guaranteeing that it is truly acting as a heartbeat mechanism.
