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	Supported Start Agent Version	Supported End Agent Version	Description
invocationDetail	radio	JAVA	false	2.0.0	-	Whether to collect call details such as parameters and return values (Default: not collect)
invocationLength	integer	JAVA	1000	2.0.0	-	Length of the call details to be collected (Default: 1000 bytes)
attachmentDetail	radio	JAVA	false	2.0.0	-	Whether to collect attachment (Default: not collect)
attachmentLength	integer	JAVA	1000	2.0.0	-	Length of the attachment to be collected (Default: 1000 bytes)
attachmentKeys	array	JAVA	-	2.0.0	-	Key to be collected from Dubbo attachment
fieldFilterKeys	array	JAVA	-	2.0.0	-	Sensitive information key to be filtered from Dubbo call parameters and returned information
slowRequestThreshold	integer	JAVA	800	2.0.0	-	Threshold for determining that a request is slow (unit: ms)
slowTraceCountStats	string	JAVA	100,50,10,2	2.0.0	-	Sampling 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.)
errorTraceCountStats	string	JAVA	100,50,10,2	2.0.0	-	Default sampling ratio configuration when an error call 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.)
traceCountStats	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.)
excludeMethods	string	JAVA	[{"group":"mock"},{"service":"mock*"}]	2.0.0	-	Method not to be traced
specMethods	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.
DefaultSampleConfig	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.)
