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

| <p>The command retrieves context info for given context ID. |
| A context corresponds to an execution thread or process. |
| 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> |
