||
| mongodb 监控采集插件，由mongodb-exporter（https://github.com/percona/mongodb_exporter）封装而来。 | ||
|
|
||
| ## Configuration | ||
|
|
||
|
|
||
|
|
||
| - 配置文件，[参考示例](../../conf/input.mongodb/mongodb.toml) | ||
| - 配置权限，至少授予以下权限给配置文件中用于连接 MongoDB 的 user 才能收集指标： | ||
| ``` | ||
| { | ||
| "role":"clusterMonitor", | ||
| "db":"admin" | ||
| }, | ||
| { | ||
| "role":"read", | ||
| "db":"local" | ||
| } | ||
| ``` | ||
| 更详细的权限配置请参考[官方文档](https://www.mongodb.com/docs/manual/reference/built-in-roles/#mongodb-authrole-clusterMonitor) | ||
|
|
||
| ## 监控大盘和告警规则 | ||
|
|
||
| 同级目录下的 dashboard.json、alerts.json 可以直接导入夜莺使用。 |
