docker - 无法使用 cassandra 导出器从 Cassandra docker 容器中抓取指标

Question

我正在尝试使用此cassandra-exporter监视在 docker 容器中运行的 Cassandra 。由于某些原因，cassandra-exporter 无法从 cassandra 中抓取指标，如果我使用docker logs -f cassandra-exporter我会得到以下输出：

Waiting for Cassandra JMX to start on  localhost:7199

我认为出口商运行良好。我必须为 cassandra 容器打开其他端口吗？还是我缺少一些环境变量？

这是我正在运行的容器：
