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.)

Call Length

integer

JAVA

1000

2.0.0

-

Key to be collected from Dubbo attachment.

Filter Key

JAVA

-

2.0.0

-

Sensitive information key to be filtered from Dubbo call parameters and returned information.
