可以使用名为 CamelMetricsName 的标头来覆盖 URI 中定义的指标名称。
例如：
from("direct:in")
.setHeader(MetricsConstants.HEADER_METRIC_NAME, constant("new.name"))
.to("metrics:counter:name.not.used")
.to("direct:out");
from("direct:in")
.setHeader(MetricsConstants.HEADER_METRIC_NAME, constant("new.name"))
.to("metrics:counter:name.not.used")
.to("direct:out");
将更新名为 new.name 而不是 name.not.used 的计数器。
指标端点完成交换处理后，所有特定于指标的标头都会从消息中删除。在处理交换指标端点时，将使用级别 warn 来捕获所有异常和写入日志条目。
