Parameter	Mandatory	Type	Description
appRules	No	Array of AppRules objects	Service parameters.

**Table 4** AppRules
Parameter	Mandatory	Type	Description
createTime	No	String	Creation time. When creating an application discovery rule, leave this parameter blank. When modifying an application discovery rule, enter the returned createTime.
enable	Yes	Boolean	Whether a rule is enabled. Value: true or false.
eventName	Yes	String	aom_inventory_rules_event Rule event name. For application discovery, the fixed value is aom_inventory_rules_event. Enumeration values: aom_inventory_rules_event
hostid	No	Array of strings	Host ID (not used currently and can be left empty).
id	Yes	String	Rule ID. When creating an application discovery rule, leave this parameter blank. When modifying an application discovery rule, enter a rule ID.
name	Yes	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.
projectid	Yes	String	Project ID obtained from IAM. Generally, a project ID contains 32 characters.
spec	Yes	AppRulesSpec object	Rule details.

**Table 5** AppRulesSpec
Parameter	Mandatory	Type	Description
appType	No	String	Service type, which is used only for rule classification and UI display. You can enter any field. For example, enter Java or Python by technology stack. You can also enter collector or database by function.
attrList	No	Array of strings	Attribute list (not used currently and can be left empty). Value: cmdLine or env.
detectLog	No	String	Whether to enable log collection. Value: true or false.
discoveryRule	Yes	Array of DiscoveryRule 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.
isDefaultRule	Yes	String	Whether the current rule is the default one. Value: true or false.
isDetect	Yes	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. Value: true or false.
logFileFix	No	Array of strings	Log file suffix. Value: log, trace, or out.
logPathRule	No	Array of LogPathRule 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.
nameRule	Yes	NameRule object	Naming rules for discovered services and applications.
priority	Yes	String	Rule priority. An integer ranging from 1 to 9999. The default value is 9999.

**Table 6** DiscoveryRule
Parameter	Mandatory	Type	Description
checkContent	Yes	Array of strings	Matched value.
checkMode	Yes	String	Match condition. Value: contain or equals.
checkType	Yes	String	Match type. Value: cmdLine, env, or scope.

**Table 7** LogPathRule
Parameter	Mandatory	Type	Description
args	No	Array of strings	Command.
nameType	No	String	Value type. Option: cmdLineHash.
value	No	Array of strings	Log path.

**Table 8** NameRule
Parameter	Mandatory	Type	Description
appNameRule	Yes	Array of AppNameRule objects	Service name rule. If there are multiple objects in the array, the character strings extracted from these objects constitute the service name. If the value of nameType is cmdLine, args is in the format of ["start", "end"], indicating that the characters between start and end in the command are extracted. If the value of nameType is cmdLine, args is in the format of ["aa"], indicating that the environment variable named aa is extracted. If the value of nameType is str, args is in the format of ["fix"], indicating that the service name is suffixed with fix. If the value of nameType is cmdLineHash, args is in the format of ["0001"] and value is in the format of ["ser"], indicating that the service name is ser when the startup command is 0001.
applicationNameRule	Yes	Array of ApplicationNameRule objects	Application name rule. If the value of nameType is cmdLine, args is in the format of ["start", "end"], indicating that the characters between start and end in the command are extracted. If the value of nameType is cmdLine, args is in the format of ["aa"], indicating that the environment variable named aa is extracted. If the value of nameType is str, args is in the format of ["fix"], indicating that the service name is suffixed with fix. If the value of nameType is cmdLineHash, args is in the format of ["0001"] and value is in the format of ["ser"], indicating that the application name is ser when the startup command is 0001.
