Question

我尝试使用JMX为cassandra集群设置zabbix监控我在节点上收到以下错误。请帮我解决这个问题，

在zabbix ui中，cassandra主持人向我显示了这个错误：

java.lang.SecurityException: Authentication failed! Credentials required

您必须在JMX项目中设置有效的用户名和密码。使用var series1 = new LineSeries { Title = "Stage I", MarkerType = MarkerType.Circle, Smooth = true, TrackerFormatString = "Stage I\nYear: {2:0.0}\n{4:0.0} %" }; //let's say I have a line series like this //I need to enter some sort of text on the plot that has the values of the below points: series1.Points.Add(new DataPoint(0.0, 100.0)); series1.Points.Add(new DataPoint(1, 82.3)); series1.Points.Add(new DataPoint(3, 59.2)); series1.Points.Add(new DataPoint(5, 47.7));测试用户名和密码。

cassandra中的jmx身份验证失败（zabbix）
