URL Monitoring

This section describes the types, names, and meanings of URL metrics collected by APM.

Table 1 Collection parameters for URL monitoring

Parameter	Data Type	Application Type	Default	Supported Start Agent Version	Supported End Agent Version	Description
Key for Header Value Interception	array	JAVA	-	2.0.0	-	Key based on which header value content is to be intercepted
Key for Parameter Value Interception	array	JAVA	-	2.0.0	-	Key based on which parameter value content is to be intercepted
Key for Cookie Value Interception	array	JAVA	-	2.0.0	-	Key based on which cookie value content is to be intercepted
URL Collection Configuration	obj_array	JAVA	-	2.0.0	-	URL collection configuration, based on which RESTful URLs are normalized. There are four modes: "startwith", "endwith", "include", and "regex".
Blocklist Configuration	obj_array	JAVA	-	2.0.0	-	URLs that match the specified rule will not be collected. There are four modes: "startwith", "endwith", "include", and "regex".
Service Code Length	integer	JAVA	0	2.0.0	-	Maximum length of the body content to be collected for service code parsing
Key for Service Code Interception	array	JAVA	-	2.0.0	-	Specify a key. Then the system parses the key in the body (JSON) and obtains the service status code based on the key.
Normal Service Code	array	JAVA	-	2.0.0	-	Normal service code range. If a service code is not within this range, the corresponding trace is regarded as an error trace.
Slow Request Threshold	integer	JAVA	800	2.0.0	-	Slow request threshold. If the threshold is crossed, the URL is regarded as a slow URL. In that case, the trace sampling ratio will be increased by default.
URL Configuration	obj_array	JAVA	-	2.0.0	-	Configure the slow request threshold and sampling ratio for each URL separately. The following sampling policies can be set: percentage sampling, fixed-quantity sampling per minute, and automatic sampling.
Error Code	radio	JAVA	500	2.0.0	-	Status codes that are counted as errors
Auto URL Normalization	radio	JAVA	false	2.3.11	-	Whether the URL will be automatically normalized
