**Table 4** Response body parameters
Parameter	Type	Description
app_rules	Array of AppRuleV1 objects	Application Discovery Rules

**Table 5** AppRuleV1
Parameter	Type	Description
project_id	String	Project ID obtained from IAM. Generally, a project ID contains 32 characters.
id	String	Rule ID. When creating an application discovery rule, leave this parameter blank. When modifying an application discovery rule, enter a rule ID.
name	String	Rule name. The value can contain a maximum of 64 characters. It must start with a lowercase letter and cannot end with a hyphen (-). Only digits, lowercase letters, and hyphens are allowed.
enable	Boolean	Whether a rule is enabled. Value: true or false.
host_id	Array of strings	Host ID (not used currently and can be left empty).
event_name	String	aom_inventory_rules_event Rule event name. For service discovery, the fixed name is aom_inventory_rules_event.
spec	AppRulesSpecV1 object	Additional information.
create_time	String	Creation time. When creating an application discovery rule, leave this parameter blank. When modifying an application discovery rule, enter the returned createTime.
desc	String	Rule description.

**Table 6** AppRulesSpecV1
Parameter	Type	Description
app_type	String	Service type, which is used only for rule classification and UI display. You can enter any field. For example, enter Java or Python to specify a technology stack. You can also enter collector or database to specify a function.
attr_list	Array of strings	Attribute list (not used currently and can be left empty).
discovery_rule	Array of DiscoveryRuleV1 objects	Discovery rule. When it is an array consisting of multiple conditions, only the processes that meet all the conditions are filtered.If the value of checkType is cmdLine, set the value of checkMode to contain. checkContent is in the format of ["xxx"], indicating that the process must contain the xxx parameter. If the value of checkType is env, set the value of checkMode to contain. checkContent is in the format of ["k1","v1"], indicating that the process must contain the environment variable whose name is k1 and value is v1. If the value of checkType is scope, set the value of checkMode to equals. checkContent is in the format of ["hostId1","hostId2"], indicating that the rule takes effect only on specified nodes. If no nodes are specified, the rule applies to all nodes of the project.
name_rule	NameRuleV1 object	Naming rules for discovered services and applications.
detect_log	String	Whether to enable log collection. Value: true or false
log_file_fix	Array of strings	Log file suffix. Value: log, trace, or out
priority	Integer	Rule priority. Value: 1–9999 (default)
is_detect	String	Whether the scenario is a pre-check scenario. No rules will be saved in the pre-check scenario. This scenario is designed only to check whether a rule can detect node processes before it is delivered. true or false
data_source	String	Data source.
editable	String	Whether a rule can be modified. If editable is set to "false", the rule is a system rule and cannot be deleted.
is_default_rule	String	Whether the current rule is the default one. Value: true or false
log_path_rule	Array of NameRuleContent objects	Log path configuration rule.If cmdLineHash is a fixed string, a log path or log file is specified. Otherwise, only the files whose names end with .log and .trace are collected. If the value of nameType is cmdLineHash, args is in the format of ["00001"] and value is in the format of ["/xxx/xx.log"], indicating that the log path is /xxx/xx.log when the startup command is 00001.
aom_metric_relabel_configs	Array of Map<String,String> objects	Metric configuration.

**Table 7** DiscoveryRuleV1
Parameter	Type	Description
check_type	String	Match type. Value: cmdLine, env, or scope
check_mode	String	Match condition. Value: contain or equals
check_content	Array of strings	Matched value.

**Table 8** NameRuleV1
Parameter	Type	Description
app_name_rule	Array of NameRuleContent objects	Component naming rule.
application_name_rule	Array of NameRuleContent objects	Application naming rule.
environment	Array of NameRuleContent objects	Environment information.

**Table 9** NameRuleContent
Parameter	Type	Description
name_type	String	Value type.
args	Array of strings	Command.
value	Array of strings	Log path.
