DubboProvider Monitoring

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

Table 1 DubboProvider collection parameters

Parameter	Data Type	Application Type	Default Value	Start Agent Version	End Agent Version	Description
Slow Request Threshold	integer	JAVA	800	2.0.0	-	Threshold for determining that a request is slow (unit: ms).
Sampling Ratio Configuration upon Slow Trace Detection	string	JAVA	100,50,10,2	2.0.0	-	Sampling ratio configuration to be applied when a slow request is detected (Example: For "100,50,10,2", the first three values respectively indicate the sampling ratio (%) under low, medium, and high CPU loads, and the last value indicates the minimum number of samples to be collected for each method.)
Sampling Ratio Configuration upon Error Trace Detection	string	JAVA	100,50,10,2	2.0.0	-	Sampling ratio configuration to be applied when an error trace is detected (Example: For "100,50,10,2", the first three values respectively indicate the sampling ratio (%) under low, medium, and high CPU loads, and the last value indicates the minimum number of samples to be collected for each method.)
Default Sampling Ratio Configuration	string	JAVA	20,10,5,1	2.0.0	-	Default sampling ratio configuration (Example: For "20,10,5,1", the first three values respectively indicate the sampling ratio (%) under low, medium, and high CPU loads, and the last value indicates the minimum number of samples to be collected for each method.)
Excluded Method	string	JAVA	[{"group":"mock"},{"service":"mock*"}]	2.0.0	-	Method not to be traced.
Method Match Rule	string	JAVA	{{"group":"mock"}:{"percentage":10,"periodCount":1000,"sampleType":"4","slowRequestThreshold":800}}	2.0.0	-	Only call information about the methods that match the rule is collected.
Default Sampling Configuration	string	JAVA	{"percentage":10,"periodCount":1000,"sampleType":"4","slowRequestThreshold":800}	2.0.0	-	Default sampling configuration (If you customize Dubbo sampling, your configuration will overwrite the global configuration of APM.)
Collect Call Details	radio	JAVA	false	2.0.0	-	Whether to collect call details such as parameters and return values (Default: not collect).
Call Length	integer	JAVA	1000	2.0.0	-	Length of the call details to be collected (Default: 1,000 bytes).
Collect Attachment	radio	JAVA	false	2.0.0	-	Whether to collect attachment (Default: not collect).
Attachment Length	integer	JAVA	1000	2.0.0	-	Length of the attachment to be collected (Default: 1,000 bytes).
Attachment Key	array	JAVA	-	2.0.0	-	Key to be collected from Dubbo attachment.
Filter Key	array	JAVA	-	2.0.0	-	Sensitive information key to be filtered from Dubbo call parameters and returned information.
