org.alfresco.heartbeat.SystemUsageDataCollector

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

public class SystemUsageDataCollector
extends HBBaseDataCollector
implements org.springframework.beans.factory.InitializingBean

A collector of data related the Runtime data of the system. Every Java application has a single instance of class Runtime that allows the application to interface with the environment in which the application is running.

• Collector ID: acs.repository.usage.system
• Data:
  • mem: Object which contains memory information:
    • free: Long - The amount of free memory in the Java Virtual Machine. Runtime.freeMemory()
    • max: Long -T he maximum amount of memory that the Java virtual machine will attempt to use. Runtime.maxMemory()
    • total: Long - The total amount of memory in the Java virtual machine. Runtime.totalMemory()
  • openFileDescriptorCount: Long - The number of open file descriptors. UnixOperatingSystemMXBean.getOpenFileDescriptorCount()
  • cpu: Object which contains processor information:
    • percentageProcessLoad: Integer - The "recent cpu usage" for the JVM process (as a percentage). OperatingSystemMXBean.getProcessCpuLoad()
    • percentageSystemLoad: Integer - The "recent cpu usage" for the whole system (as a percentage). OperatingSystemMXBean.getSystemCpuLoad()
    • systemLoadAverage: Double - The system load average as returned by OperatingSystemMXBean.getSystemLoadAverage()
    • availableProcessors: Integer - The number of available processors. Runtime.availableProcessors()
  • db: Object which contains database usage information:
    • idleConnections: Integer - The number of idle connections. BasicDataSource.getNumIdle()
    • activeConnections: Integer - The number of active connections. BasicDataSource.getNumActive()
