我想使用 elastcisearch 在 kibana 中显示 jmx 指标。我在 jar 下面起诉以在某些端口中公开 tomcat 指标“jmx_prometheus_javaagent-0.6.jar”，例如。9999 我正在使用以下配置 metricbeat.yml

metricbeat.modules:
- module: prometheus
  metricsets: ["collector"]
  period: 10s
  hosts: ["tomcat_ip:port"]
  metrics_path: /metrics
  namespace: example

我收到以下错误：
