我有一个mongodb_exporter的问题（prometheus metrics exporter for mongodb）.我想这是因为我这边的配置问题，但经过2天的搜索，我没有解决方案：）
我在K8S上运行mongodb，并将mongodb_exporter作为边车吊舱运行。（我认为，因为没有错误），显示一些指标，但我的问题是，这只是"执行"指标（见下文），我只有一个"mongodb"指标!!=〉mongodb_up 1.即使我设置了选项"--collect-all"或"--collector. collstats"。我的"config"中没有任何"有用的"指标。数据库，如集合大小等....
连接到数据库是确定的，因为如果我改变用户名/密码/数据库端口，我运行到连接问题。我认为我的用户有正确的权利（在我的文本中更改真实密码为"密码"）：

Successfully added user: {
        "user" : "exporter",
        "roles" : [
                {
                        "role" : "clusterMonitor",
                        "db" : "admin"
                },
                {
                        "role" : "read",
                        "db" : "local"
                }
        ]
}
