CSEProvider Cluster Monitoring

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

**Table 1** CSEProvider collection parameters
Parameter	Data Type	Application Type	Default	Supported Start Agent Version	Supported End Agent Version	Description
Blocklist Configuration	obj_array	JAVA	-	2.0.0	-	URLs in the blacklist will not be collected. There are four modes: "startwith", "endwith", "include", and "regex".
Max. Status Code Length	integer	JAVA	0	2.0.0	-	The system parses the body content within the specified length and obtains the corresponding service status code.
Key for Status Code Parsing	array	JAVA	-	2.0.0	-	Key based on which the corresponding body content is to be obtained and reported as the service status code
Normal Status Code	array	JAVA	-	2.0.0	-	If the obtained status code is not within the range, the request is regarded as an error trace.
Slow Request Threshold	integer	JAVA	800	2.0.0	-	Slow request threshold. If the threshold is crossed, a URL will be regarded as a slow URL. The system will automatically increase the sampling ratio for it.
Slow URL Threshold	obj_array	JAVA	-	2.0.0	-	Slow request threshold. If this threshold is crossed, the URL is defined as a slow URL. In that case, the system automatically increases the sampling ratio for it. There are four sampling policies: 1. Full sampling; 2. Percentage sampling; 3. Fixed-quantity sampling per minute; 4. Automatic sampling.
Key for Header Value Interception	array	JAVA	-	2.0.0	-	Key based on which header value content is to be intercepted
