SigarMetricsCollector

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.

  11. def cpuCombined: 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 https://bugzilla.redhat.com/show_bug.cgi?id=749121 and several others.

    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. 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.
