    • getCpuCount

      int getCpuCount()
      Number of CPU cores that the media server can use.

      Linux processes can be configured to use only a subset of the cores that are available in the system, via the process affinity settings (sched_setaffinity(2)). With this method it is possible to know the number of cores that the media server can use in the machine where it is running.

      For example, it's possible to limit the core affinity inside a Docker container by running with a command such as docker run --cpuset-cpus='0,1'.

      Note that the return value represents the number of logical processing units available, i.e. CPU cores including Hyper-Threading.

      Returns:
      Number of CPU cores available for the media server. *

    • getCpuCount

      void getCpuCount(Continuation<Integer> cont)
      Asynchronous version of getCpuCount: Continuation.onSuccess(F) is called when the action is done. If an error occurs, Continuation.onError(java.lang.Throwable) is called.
      See Also:

    • getCpuCount

      TFuture<Integer> getCpuCount(Transaction tx)
      Number of CPU cores that the media server can use.

      Returns:
      Number of CPU cores available for the media server. *

    • getUsedCpu

      float getUsedCpu(int interval)
      Average CPU usage of the server.

      This method measures the average CPU usage of the media server during the requested interval. Normally you will want to choose an interval between 1000 and 10000 ms.

      The returned value represents the global system CPU usage of the media server, as an average across all processing units (CPU cores).

      Parameters:
      interval - Time to measure the average CPU usage, in milliseconds.
      Returns:
      CPU usage %. *

    • getUsedCpu

      void getUsedCpu(int interval, Continuation<Float> cont)
      Asynchronous version of getUsedCpu: Continuation.onSuccess(F) is called when the action is done. If an error occurs, Continuation.onError(java.lang.Throwable) is called.
      Parameters:
      interval - Time to measure the average CPU usage, in milliseconds.
      See Also:

    • getUsedCpu

      TFuture<Float> getUsedCpu(Transaction tx, int interval)
      Average CPU usage of the server.

      This method measures the average CPU usage of the media server during the requested interval. Normally you will want to choose an interval between 1000 and 10000 ms.

      The returned value represents the global system CPU usage of the media server, as an average across all processing units (CPU cores).
