Question

我使用node-opcua包对几个nodeIds进行了设置监控。它工作正常一段时间，但后来开始打印一些超时消息。

以下是我服务的journalctl输出：

基本上我希望永远保持监控，每15分钟发布一次。因此，如果有人能够帮助我完成这些参数，那将会非常棒。

如果您有权访问服务器，可以查看此post。

在帖子中，他们声明，当您设置客户端时，requestedLifetimeCount * requestedPublishingInterval应设置为至少PublishRequest.RequestHeader.timeoutHint：

＆＃13;

var options = {
  requestedPublishingInterval: 1000, // check on server
  requestedMaxKeepAliveCount: 2,
  requestedLifetimeCount: 100, // check on server
  maxNotificationsPerPublish: 10,
  publishingEnabled: true,
  priority: 10,
}

var subscription = new opcua.ClientSubscription(opcSession, options);
