Host Group Configuration

The following API commands enable you to configure host groups:

config server:hostgroups::get

The config server:hostgroups::get command enables you to get a list of host groups defined in the Control-M/Server. Each entry is a host group name. The list includes only those host groups that you are authorized to manage.

CLI Syntax

Copy 
ctm config server:hostgroups::get <server>

Where server is the name of the Control-M/Server.

REST API Syntax

cURL:

Copy 
server=controlm
AuthHeader="x-api-key: $token"
# AuthHeader="Authorization: Bearer $token"  #for a session token

curl -H "$AuthHeader" "$endpoint/config/server/$server/hostgroups"

To determine the correct AuthHeader value—"Authorization: Bearer $token" or "x-api-key: $token"—see Authentication Tokens.

config server:hostgroup::update

The config server:hostgroup::update command enables you to update the list of Agents that are in a host group. This overwrites the current list of Agents. If the specified host group does not exist, a new host group is created.

This API command is especially useful if you want to add or remove multiple Agents in a host group all at once, or create a new host group with multiple associated Agents.

For more information about host group definitions, including participation rules, see Host Group Data File.

CLI Syntax

Copy 
ctm config server:hostgroup::update <server> <hostgroup> -f <configuration file>

The following table describes the config server:hostgroup::update command parameters.

Parameter

Description

server

Name of Control-M/Server.

hostgroup

Name of host group.

configuration file

JSON file that contains definitions and participation rules of Control-M/Agents within the host group, as described in Host Group Data File.

The configuration file must contain definitions of at least one agent.

Participation rules limit the inclusion of the Agent host in the host group to scheduled dates and times or in response to events.

The hostgroupAgentParticipation object, which was used in the past to define participation rules, has been deprecated and has been replaced by the participationRules object. To support backward compatibility, this API command still recognizes the hostgroupAgentParticipation object.

As your starting point, you can use config server:hostgroup:agents::get to obtain a list of all defined Agents in a host group. Ensure that you edit the output from that command to match the required format described in Host Group Data File.

If annotation is enabled for the Configuration Management category in the CCM, you must also provide an annotation to justify your action. For more information, see Annotation Input.

REST API Syntax

cURL, with one Agent defined in the host group:

Copy 
server=myServer
hostgroup=myHostGroup
AuthHeader="x-api-key: $token"
# AuthHeader="Authorization: Bearer $token"  #for a session token

curl -H "$AuthHeader" -H "Content-Type: application/json" -X POST --data "hostGroupDefinitions.json" "$endpoint/config/server/$server/hostgroup/$hostgroup"

To determine the correct AuthHeader value—"Authorization: Bearer $token" or "x-api-key: $token"—see Authentication Tokens.

config server:hostgroup::delete

The config server:hostgroup::delete command enables you to delete a specified host group from the Control-M/Server, provided that you are authorized to manage this host group.

CLI Syntax

Copy 
ctm config server:hostgroup::delete <server> <hostgroup>

The following table describes the config server:hostgroup::delete command parameters.

Parameter

Description

server

Name of Control-M/Server.

hostgroup

Name of host group.

If annotation is enabled for the Configuration Management category in the CCM, you must also provide an annotation to justify your action. For more information, see Annotation Input.

REST API Syntax

cURL:

Copy 
server=myServer
hostgroup=myHostGroup
AuthHeader="x-api-key: $token"
# AuthHeader="Authorization: Bearer $token"  #for a session token

curl -H "$AuthHeader" -X DELETE "$endpoint/config/server/$server/hostgroup/$hostgroup"

To determine the correct AuthHeader value—"Authorization: Bearer $token" or "x-api-key: $token"—see Authentication Tokens.

config server:hostgroups:agents::get

The config server:hostgroups:agents::get command enables you to get the list of host groups defined in the Control-M/Server, along with the list of Agents in each host group. The list includes only those host groups that you are authorized to manage.

For each Agent, details of the defined participation rules are provided. Participation rules limit the inclusion of the Agent host in the host group to scheduled dates and times or in response to events, as described in Host Group Data File.

The hostgroupAgentParticipation object, which was used in the past to define participation rules, has been deprecated and has been replaced by the participationRules object.

CLI Syntax

Copy 
ctm config server:hostgroups:agents::get <server>

where server is the name of a Control-M/Server.

REST API Syntax

cURL:

Copy 
server=controlm
AuthHeader="x-api-key: $token"
# AuthHeader="Authorization: Bearer $token"  #for a session token

curl -H "$AuthHeader" "$endpoint/config/server/$server/hostgroups/agents"

To determine the correct AuthHeader value—"Authorization: Bearer $token" or "x-api-key: $token"—see Authentication Tokens.

config server:hostgroup:agents::get

The config server:hostgroup:agents::get command enables you to get the list of Agents in a host group, provided that you are authorized to manage this host group. Each entry is the logical name of an Agent.

For each Agent, details of the defined participation rules are provided. Participation rules limit the inclusion of the Agent host in the host group to scheduled dates and times or in response to events, as described in Host Group Data File.

The hostgroupAgentParticipation object, which was used in the past to define participation rules, has been deprecated and has been replaced by the participationRules object.
