Backend modules beans
Introduction: The beans module is a job scheduler, and is essentially a wrapper around Quartz, which might be described as a beefier, platform-agnostic Cron jobs alternative that can be embedded in a Java project.
The beans module is used extensively when monitoring hosts. The VDSBroker module’s class VdsUpdateRunTimeInfo monitors hosts’ CPU, memory usage and so on. A method of the IRSBrokerCommand class monitors the SPM-host for storage related issues.
