<p>The service can be used for monitoring system activity and utilization.
|
|
|
43 |
It provides list of running processes, different process attributes like command line, environment, etc.,
|
|
|
44 |
and some resource utilization data. The service can be used by a client to provide functionality
|
|
|
45 |
similar to Unix 'top' utility or Windows 'Task Manager'.</p>
|
|
|
46 |
|
|
|
47 |
<p>Command and event parameters are encoded
|
|
|
48 |
as zero terminated <a href='TCF Specification.html#JSON'>JSON</a> strings.</p>
|
|
|
49 |
|
|
|
50 |
<p>The service uses standard format for error reports,

<p>The command retrieves context info for given context ID.

A context corresponds to an execution thread or process.
|
|

63 |
Context IDs are valid across TCF services, so it is allowed to issue 'SysMonitor.getContext'
|

command with a context that was obtained from another service.</p>
