Polygon Bor节点 opencollector-endpoint 错误解决

[telemetry]
    metrics = true
    # expensive = false
    # prometheus-addr = ""
    # opencollector-endpoint = ""

如上所示，我启用了普罗米修斯指标。节点启动后，出现错误：

Jun 14 03:13:24 polygon-01 bor[26057]: 2023/06/14 03:13:24 traces exporter is disconnected from the server 127.0.0.1:4317: max retry time elapsed: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:4317: connect: connection refused"

问题原因为：

opencollector-endpoint 参数默认值为 127.0.0.1:4317。节点启动后，我发现4317端口没有打开。但启用指标后，bor 会尝试连接它，所以出现了这个以上这个错误

如果你有一个侦听器监听该端口的跟踪。如果您希望它被禁用，只需取消注释并传递opencollector-endpoint = ""，如下所示：

    metrics = true
    # expensive = false
    # prometheus-addr = ""
    opencollector-endpoint = ""

以上就是今天分享的Polygon 区块生产者层Bor节点出现的节点报错问题，希望可以帮助到你们。
