    • Method Detail

      • getCpuAcctControlGroup

        public java.lang.String getCpuAcctControlGroup()
        The control group for the cpuacct subsystem.
        Returns:
        the control group
      • getCpuAcctUsageNanos

        public long getCpuAcctUsageNanos()
        The total CPU time consumed by all tasks in the cpuacct control group from cpuAcctControlGroup.
        Returns:
        the total CPU time in nanoseconds
      • getCpuControlGroup

        public java.lang.String getCpuControlGroup()
        The control group for the cpu subsystem.
        Returns:
        the control group
      • getCpuCfsPeriodMicros

        public long getCpuCfsPeriodMicros()
        The period of time for how frequently the control group from cpuControlGroup has its access to CPU resources reallocated.
        Returns:
        the period of time in microseconds
      • getCpuCfsQuotaMicros

        public long getCpuCfsQuotaMicros()
        The total amount of time for which all tasks in the control group from cpuControlGroup can run in one period as represented by cpuCfsPeriodMicros.
        Returns:
        the total amount of time in microseconds
      • getMemoryControlGroup

        public java.lang.String getMemoryControlGroup()
        The control group for the memory subsystem.
        Returns:
        the control group
      • getMemoryLimitInBytes

        public java.lang.String getMemoryLimitInBytes()
        The maximum amount of user memory (including file cache). This is stored as a String because the value can be too big to fit in a long. (The alternative would have been BigInteger but then it would not be possible to index the OS stats document into Elasticsearch without losing information, as BigInteger is not a supported Elasticsearch type.)
        Returns:
        the maximum amount of user memory (including file cache).
      • getMemoryUsageInBytes

        public java.lang.String getMemoryUsageInBytes()
        The total current memory usage by processes in the cgroup (in bytes). This is stored as a String for consistency with memoryLimitInBytes.
        Returns:
        the total current memory usage by processes in the cgroup (in bytes).
