• naclDebugPort

  number

  The debugging port for Native Client processes. Zero for other process types and for NaCl processes that do not have debugging enabled.

• network

• profile

  string

  The profile which the process is associated with.

• scriptCache

  Cache optional

  The most recent information about the script cache for the process. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.

Enum

Parameters

• tabId

  number

  The ID of the tab for which the renderer process ID is to be returned.

• callback

  function

  A callback to return the ID of the renderer process of a tab.

  The callback parameter should be a function that looks like this:

  • processId

    number

    Process ID of the tab's renderer process.

Parameters

• processIds

  number | number[]

  The list of process IDs or single process ID for which to return the process information. An empty list indicates all processes are requested.

• includeMemory

  boolean

  True if detailed memory usage is required. Note, collecting memory usage information incurs extra CPU usage and should only be queried for when needed.

• callback

  function

  A callback called when the processes information is collected.

  The callback parameter should be a function that looks like this:

  (processes: object) => {...}

  • processes

    object

    A dictionary of Process objects for each requested process that is a live child process of the current browser process, indexed by process ID. Metrics requiring aggregation over time will not be populated in each Process object.

Parameters

• processId

  number

  The ID of the process to be terminated.

• callback

  function

  A callback to report the status of the termination.

  The callback parameter should be a function that looks like this:

  (didTerminate: boolean) => {...}

  • didTerminate

    boolean

    True if terminating the process was successful, and false otherwise.

• listener

  function

  The listener parameter should be a function that looks like this:

  (process: Process) => {...}
