This constructor is used when creating an instance from configured FQCN
The akka.actor.Address of the node being sampled
the org.hyperic.Sigar instance
Releases any native resources associated with this instance.
Releases any native resources associated with this instance.
(SIGAR) Returns the combined CPU sum of User + Sys + Nice + Wait, in percentage.
(SIGAR) Returns the combined CPU sum of User + Sys + Nice + Wait, in percentage. This metric can describe the amount of time the CPU spent executing code during n-interval and how much more it could theoretically. Note that 99% CPU utilization can be optimal or indicative of failure.
In the data stream, this will sometimes return with a valid metric value, and sometimes as a NaN or Infinite. Documented bug https://bugzilla.redhat.com/show_bug.cgi?id=749121 and several others.
Creates a new instance each time.
(JMX) Returns the current sum of heap memory guaranteed to be available to the JVM from all heap memory pools (in bytes).
(JMX) Returns the current sum of heap memory guaranteed to be available to the JVM from all heap memory pools (in bytes). Creates a new instance each time.
(JMX) Returns the maximum amount of memory (in bytes) that can be used for JVM memory management.
(JMX) Returns the maximum amount of memory (in bytes) that can be used for JVM memory management. If not defined the metrics value is None, i.e. never negative. Creates a new instance each time.
Current heap to be passed in to heapUsed, heapCommitted and heapMax
Current heap to be passed in to heapUsed, heapCommitted and heapMax
(JMX) Returns the current sum of heap memory used from all heap memory pools (in bytes).
(JMX) Returns the current sum of heap memory used from all heap memory pools (in bytes). Creates a new instance each time.
(JMX) Returns the number of available processors Creates a new instance each time.
(JMX) Returns the number of available processors Creates a new instance each time.
Samples and collects new data points.
Samples and collects new data points. Creates a new instance each time.
(SIGAR / JMX) Returns the OS-specific average load on the CPUs in the system, for the past 1 minute.
(SIGAR / JMX) Returns the OS-specific average load on the CPUs in the system, for the past 1 minute. On some systems the JMX OS system load average may not be available, in which case a -1 is returned from JMX, which means that None is returned from this method. Hyperic SIGAR provides more precise values, thus, if the library is on the classpath, it is the default. Creates a new instance each time.
Loads metrics through Hyperic SIGAR and JMX monitoring beans. This loads wider and more accurate range of metrics compared to JmxMetricsCollector by using SIGAR's native OS library.
The constructor will by design throw exception if org.hyperic.sigar.Sigar can't be loaded, due to missing classes or native libraries.
