Method Details

unapply

public scala.Option<scala.Tuple6<Address,Object,scala.Option<Object>,scala.Option<Object>,scala.Option<Object>,Object>> unapply(NodeMetrics nodeMetrics)

Given a NodeMetrics it returns the Cpu data if the nodeMetrics contains necessary cpu metrics.

Returns:

if possible a tuple matching the Cpu constructor parameters

apply

public StandardMetrics.Cpu apply(Address address,
 long timestamp,
 scala.Option<Object> systemLoadAverage,
 scala.Option<Object> cpuCombined,
 scala.Option<Object> cpuStolen,
 int processors)

Parameters:

address - pekko.actor.Address of the node the metrics are gathered at

timestamp - the time of sampling, in milliseconds since midnight, January 1, 1970 UTC

systemLoadAverage - OS-specific average load on the CPUs in the system, for the past 1 minute, The system is possibly nearing a bottleneck if the system load average is nearing number of cpus/cores.

cpuCombined - combined CPU sum of User + Sys + Nice + Wait, in percentage ([0.0 - 1.0]. This metric can describe the amount of time the CPU spent executing code during n-interval and how much more it could theoretically.

cpuStolen - stolen CPU time, in percentage ([0.0 - 1.0].

processors - the number of available processors

unapply

public scala.Option<scala.Tuple6<Address,Object,scala.Option<Object>,scala.Option<Object>,scala.Option<Object>,Object>> unapply(StandardMetrics.Cpu x$0)
