class SigarMetricsCollector extends JmxMetricsCollector
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.

Instance Constructors
- new SigarMetricsCollector(system: ActorSystem)
This constructor is used when creating an instance from configured FQCN
- new SigarMetricsCollector(address: Address, settings: ClusterMetricsSettings)
- new SigarMetricsCollector(address: Address, settings: ClusterMetricsSettings, sigar: SigarProxy)
- new SigarMetricsCollector(address: Address, decayFactor: Double, sigar: SigarProxy)
- address
The akka.actor.Address of the node being sampled
- decayFactor
how quickly the exponential weighting of past data is decayed

- def cpuCombined(cpuPerc: CpuPerc): Option[Metric]
(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 749121 and several others.

- def cpuIdle(cpuPerc: CpuPerc): Option[Metric]
(SIGAR) Returns the idle CPU time.
(SIGAR) Returns the idle CPU time. Amount of CPU time left after combined and stolen are removed.

- def cpuStolen(cpuPerc: CpuPerc): Option[Metric]
(SIGAR) Returns the stolen CPU time.
(SIGAR) Returns the stolen CPU time. Relevant to virtual hosting environments. For details please see: Wikipedia - CPU time subdivision and Understanding AWS stolen CPU and how it affects your apps
