这是当前Jmx导出器模式：
pattern: 'metrics<name=resilience4jCircuitbreakerState.name.(.*).state.(.*), type=gauges><>Value'
name: 'x.y.z.resilience4j.circuitbreaker.state'
labels: {name: "$1", kind: "$2" }
type: GAUGE
电流输出：
x_y_z_resilience4j_circuitbreaker_state{kind="open",name="a",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="b",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="half_open",name="c",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="half_open",name="d",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="forced_open",name="e",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="disabled",name="f",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="disabled",name="g",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="forced_open",name="h",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="i",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="j",} 1.0
实际上效果很好。但是为了提高基数，我们决定不公开0.0值来修改Yml(如果有的话(。
上述样品的预期输出为
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="b",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="i",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="j",} 1.0
请随时在下面发表评论。
看起来每个name都有5个x_y_z__resilience4j_circuitbreaker_state度量，每个度量都有不同的kind标签，一个标签的值为1.0，另一个则为0.0。
在这种情况下，如果您不公开0.0，并且断路器在所有状态下发生变化，则所有度量都将报告1.0。
要减少基数，应该删除kind标签并将值设置为状态。
取而代之的是：
x_y_z__resilience4j_circuitbreaker_state{kind="disabled",name="a",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="a",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="open",name="a",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="half_open",name="a",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="forced_open",name="a",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="disabled",name="b",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="b",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="open",name="b",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="half_open",name="b",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="forced_open",name="b",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="disabled",name="c",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="closed",name="c",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="open",name="c",} 0.0
x_y_z__resilience4j_circuitbreaker_state{kind="half_open",name="c",} 1.0
x_y_z__resilience4j_circuitbreaker_state{kind="forced_open",name="c",} 0.0
你应该报告这样的事情：
x_y_z__resilience4j_circuitbreaker_state{name="a"} 1.0 # 1 represents "closed"
x_y_z__resilience4j_circuitbreaker_state{name="b"} 2.0 # 2 represents "open"
x_y_z__resilience4j_circuitbreaker_state{name="c"} 3.0 # 3 represents "half_open"
最后，下面的regex对我有效，
^(?!0(.0)?$)
