Question

What were the different process ID’s for chrome? Answers will vary.

Answer 1

Types

Cache

Properties

double	size	The size of the cache , in bytes.
double	liveSize	The part of the cache that is utilized, in bytes.

Process

Properties

integer	id	Unique ID of the process provided by the browser.
integer	osProcessId	The ID of the process, as provided by the OS.
enum of "browser" , "renderer" , "extension" , "notification" , "plugin" , "worker" , "nacl" , "service_worker" , "utility" , "gpu" , or "other"	type	The type of process.
string	profile	The profile which the process is associated with.
integer	naclDebugPort	The debugging port for Native Client processes. Zero for other process types and for NaCl processes that do not have debugging enabled.
array of object	tasks	Array of TaskInfos representing the tasks running on this process. Properties of each object string title The title of the task. integer (optional) tabid Optional tab ID, if this task represents a tab running on a renderer process.
double	(optional)cpu	The most recent measurement of the process’s CPU usage, expressed as the percentage of a single CPU core used in total, by all of the process’s threads. This gives a value from zero to CpuInfo.numOfProcessors*100, which can exceed 100% in multi-threaded processes. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
double	(optional)network	The most recent measurement of the process network usage, in bytes per second. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
double	(optional)privateMemory	The most recent measurement of the process private memory usage, in bytes. Only available when receiving the object as part of a callback from onUpdatedWithMemory or getProcessInfo with the includeMemory flag.
double	(optional)jsMemoryAllocated	The most recent measurement of the process JavaScript allocated memory, in bytes. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
double	(optional)jsMemoryUsed	The most recent measurement of the process JavaScript memory used, in bytes. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
double	(optional)sqliteMemory	The most recent measurement of the process’s SQLite memory usage, in bytes. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
Cache	(optional)imageCache	The most recent information about the image cache for the process. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.
Cache	(optional)scriptCache	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.
Cache	(optional)cssCache	The most recent information about the CSS cache for the process. Only available when receiving the object as part of a callback from onUpdated or onUpdatedWithMemory.

Methods

getProcessIdForTab

chrome.processes.getProcessIdForTab(integer tabid , function callback)

Returns the ID of the renderer process for the specified tab.

Parameters

integer	tabid	The ID of the tab for which the renderer process ID is to be returned.
function	callback	A callback to return the ID of the renderer process of a tab. The callback parameter should be a function that looks like this: function(integer processId) {...}; boolean didTerminate Process ID of the tab's renderer process.

terminate

chrome.processes.terminate(integer processId , function callback)

  Terminates the specified renderer process. Equivalent to visiting about:crash, but without changing the tab's URL.

Parameters

integer	processId	The ID of the process to be terminated.
function	(optional) callback	A callback to report the status of the termination. If you specify the callback parameter, it should be a function that looks like this: function(boolean didTerminate) {...}; boolean didTerminate True if terminating the process was successful, and false otherwise.

getProcessInfo

chrome.processes.getProcessInfo(integer or array of integer processIds , boolean includeMemory , function callback)

Retrieves the process information for each process ID specified.

Parameters

integer or array of integer	processIds	The list of process IDs or single process ID for which to return the process information. An empty list indicates all processes are requested.
boolean	includeMemory	True if detailed memory usage is required. Note, collecting memory usage information incurs extra CPU usage and should only be queried for when needed.
function	callback	A callback called when the processes information is collected. The callback parameter should be a function that looks like this: function(object processes) {...}; object processes 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.

Events

onUpdated

Fired each time the Task Manager updates its process statistics, providing the dictionary of updated Process objects, indexed by process ID.

addListener

chrome.processes.onUpdated.addListener(function callback)

function

callback

The callback parameter should be a function that looks like this: function(object processes) {...}; object processes A dictionary of updated Process objects for each live process in the browser, indexed by process ID. Metrics requiring aggregation over time will be populated in each Process object.

onUpdatedWithMemory

Fired each time the Task Manager updates its process statistics, providing the dictionary of updated Process objects, indexed by process ID. Identical to onUpdate, with the addition of memory usage details included in each Process object. Note, collecting memory usage information incurs extra CPU usage and should only be listened for when needed.

addListener

chrome.processes.onUpdatedWithMemory.addListener(function callback)

Parameters

function

callback

The callback parameter should be a function that looks like this: function(object processes) {...}; object processes A dictionary of updated Process objects for each live process in the browser, indexed by process ID. Memory usage details will be included in each Process object.

onCreated

Fired each time a process is created, providing the corrseponding Process object.

addListener

  chrome.processes.onCreated.addListener(function callback)

Parameters

function

callback

The callback parameter should be a function that looks like this: function( Process process) {...}; Process process Details of the process that was created. Metrics requiring aggregation over time will not be populated in the object.

onExited

  Fired each time a process is terminated, providing the type of exit.

  addListener

  chrome.processes.onExited.addListener(function callback)

  Parameters

  

function

callback

The callback parameter should be a function that looks like this: function(integer processId, integer exitType, integer exitCode) {...}; integer processId The ID of the process that exited. integer exitType The type of exit that occurred for the process - normal, abnormal, killed, crashed. Only available for renderer processes. integer exitCode The exit code if the process exited abnormally. Only available for renderer processes.

Hey!! I wrote the answer for you.Kindly read it properly and uprate my ratings if possible as it is the most important thing for me at the moment.
