function Disable-JS7Subagent
{
<#
.SYNOPSIS
Disables a Subagent in the JS7 Controller
 
.DESCRIPTION
This cmdlet disables a Subagent. A disabled Subagent is not considered for job execution
by the Director Agent in a Subagent Cluster. Note that the Subagent remains dedicated
to its Controller. Disabling Subagents can be useful for example in case of maintenance windows
on the Subagent's computer.
 
The following REST Web Service API resources are used:
 
* /agents/inventory/cluster/subagents/disable
 
.PARAMETER SubagentId
Specifies the unique identifier of the Subagent.
 
More than one Subagent can be specified by separating Subagent IDs by a comma.
 
.PARAMETER ControllerId
Specifies the identification of the Controller to which the Subagent is dedicated.
 
.PARAMETER AuditComment
Specifies a free text that indicates the reason for the current intervention, e.g. "business requirement", "maintenance window" etc.
 
The Audit Comment is visible from the Audit Log view of the JOC Cockpit.
This parameter is not mandatory. However, the JOC Cockpit can be configured to require Audit Log comments for all interventions.
 
.PARAMETER AuditTimeSpent
Specifies the duration in minutes that the current intervention required.
 
This information is shown in the Audit Log view. It can be useful when integrated
with a ticket system that logs the time spent on interventions with JS7.
 
.PARAMETER AuditTicketLink
Specifies a URL to a ticket system that keeps track of any interventions performed for JS7.
 
This information is shown in the Audit Log view of JOC Cockpit.
It can be useful when integrated with a ticket system that logs interventions with JS7.
 
.INPUTS
This cmdlet accepts pipelined input.
 
.OUTPUTS
This cmdlet returns no output.
 
.EXAMPLE
Disable-JS7Subagent -SubagentId 'subagent_001'
 
Disables the indicated Subagent.
