定义

db.setLogLevel()

为日志消息设置单一详细程度。

db.setLogLevel() 采用以下形式：

db.setLogLevel(<level>, <component>)

db.setLogLevel() 使用以下参数：

Parameter
类型
说明

level

int

日志详细程度。

详细程度级别的范围可以从 0 到 5：

  • 0 是 MongoDB 的默认日志详细程度级别，它包括信息性消息。

  • 1 到 5 提高详细程度级别以包括调试消息。

要继承组件父级的详细程度，也可以指定 -1。

component

字符串

可选。为其指定日志详细程度的组件的名称。组件名称对应于相应 systemLog.component.<name>.verbosity 设置中的 <name>：

省略以指定所有组件的默认详细程度。

兼容性

此方法可用于以下环境中托管的部署：

重要

MongoDB Atlas集群不支持此命令。 有关Atlas支持所有命令的信息，请参阅不支持的命令。

行为

db.setLogLevel() 设置单个详细程度。如要在一次操作中设置多个详细程度，可使用 setParameter 命令设置 logComponentVerbosity 参数。您还可以在配置文件中指定详细程度设置。有关示例，请参阅配置日志详细程度。

注意

从版本 4.2 开始，MongoDB 在日志消息中包含调试详细级别（1 至 5 级）。例如，如果详细级别为 2，则 MongoDB 记录 D2。在以前版本中，MongoDB 日志消息仅为调试级别指定 D。

示例

设置默认详细程度

省略 <component> 参数可为所有组件设置默认详细程度；即 systemLog.verbosity 设置。该操作将默认详细程度设置为 1：

db.setLogLevel(1)
{
   was: {
      verbosity: 1,
      accessControl: { verbosity: -1 },
      assert: { verbosity: -1 },
      command: { verbosity: -1 },
      control: { verbosity: -1 },
      executor: { verbosity: -1 },
      geo: { verbosity: -1 },
      globalIndex: { verbosity: -1 },
      index: { verbosity: -1 },
      network: {
         verbosity: -1,
         asio: { verbosity: -1 },
         bridge: { verbosity: -1 },
         connectionPool: { verbosity: -1 }
      },
      processHealth: { verbosity: -1 },
      query: {
         verbosity: -1,
         optimizer: { verbosity: -1 },
         ce: { verbosity: -1 }
      },
      queryStats: { verbosity: -1 },
      replication: {
         verbosity: -1,
         election: { verbosity: -1 },
         heartbeats: { verbosity: -1 },
         initialSync: { verbosity: -1 },
         rollback: { verbosity: -1 }
      },
      sharding: {
         verbosity: -1,
         rangeDeleter: { verbosity: -1 },
         shardingCatalogRefresh: { verbosity: -1 },
         migration: { verbosity: -1 },
         reshard: { verbosity: -1 },
         migrationPerf: { verbosity: -1 }
      },
      storage: {
         verbosity: -1,
         recovery: { verbosity: -1 },
         journal: { verbosity: 2 },
         wt: {
         verbosity: -1,
         wtBackup: { verbosity: -1 },
         wtCheckpoint: { verbosity: -1 },
         wtCompact: { verbosity: -1 },
         wtEviction: { verbosity: -1 },
         wtHS: { verbosity: -1 },
         wtRecovery: { verbosity: -1 },
         wtRTS: { verbosity: -1 },
         wtSalvage: { verbosity: -1 },
         wtTiered: { verbosity: -1 },
         wtTimestamp: { verbosity: -1 },
         wtTransaction: { verbosity: -1 },
         wtVerify: { verbosity: -1 },
         wtWriteLog: { verbosity: -1 }
         }
      },
      write: { verbosity: -1 },
      ftdc: { verbosity: -1 },
      tracking: { verbosity: -1 },
      transaction: { verbosity: -1 },
      tenantMigration: { verbosity: -1 },
      test: { verbosity: -1 },
      resourceConsumption: { verbosity: -1 },
      streams: { verbosity: -1 }
   },
   ok: 1
}

为组件设置详细程度

指定 <component> 参数可为组件设置详细程度。以下操作可将 systemLog.component.storage.journal.verbosity 更新为 2：

db.setLogLevel(2, "storage.journal" )
{
   was: {
      verbosity: 1,
      accessControl: { verbosity: -1 },
      assert: { verbosity: -1 },
      command: { verbosity: -1 },
      control: { verbosity: -1 },
      executor: { verbosity: -1 },
      geo: { verbosity: -1 },
      globalIndex: { verbosity: -1 },
      index: { verbosity: -1 },
      network: {
         verbosity: -1,
         asio: { verbosity: -1 },
         bridge: { verbosity: -1 },
         connectionPool: { verbosity: -1 }
      },
      processHealth: { verbosity: -1 },
      query: {
         verbosity: -1,
         optimizer: { verbosity: -1 },
         ce: { verbosity: -1 }
      },
      queryStats: { verbosity: -1 },
      replication: {
         verbosity: -1,
         election: { verbosity: -1 },
         heartbeats: { verbosity: -1 },
         initialSync: { verbosity: -1 },
         rollback: { verbosity: -1 }
      },
      sharding: {
         verbosity: -1,
         rangeDeleter: { verbosity: -1 },
         shardingCatalogRefresh: { verbosity: -1 },
         migration: { verbosity: -1 },
         reshard: { verbosity: -1 },
         migrationPerf: { verbosity: -1 }
      },
      storage: {
         verbosity: -1,
         recovery: { verbosity: -1 },
         journal: { verbosity: -1 },
         wt: {
         verbosity: -1,
         wtBackup: { verbosity: -1 },
         wtCheckpoint: { verbosity: -1 },
         wtCompact: { verbosity: -1 },
         wtEviction: { verbosity: -1 },
         wtHS: { verbosity: -1 },
         wtRecovery: { verbosity: -1 },
         wtRTS: { verbosity: -1 },
         wtSalvage: { verbosity: -1 },
         wtTiered: { verbosity: -1 },
         wtTimestamp: { verbosity: -1 },
         wtTransaction: { verbosity: -1 },
         wtVerify: { verbosity: -1 },
         wtWriteLog: { verbosity: -1 }
         }
      },
      write: { verbosity: -1 },
      ftdc: { verbosity: -1 },
      tracking: { verbosity: -1 },
      transaction: { verbosity: -1 },
      tenantMigration: { verbosity: -1 },
      test: { verbosity: -1 },
      resourceConsumption: { verbosity: -1 },
      streams: { verbosity: -1 }
   },
   ok: 1
}

获取部署的全局日志级别

以下操作获取部署的默认日志记录级别详细程度：

db.adminCommand({getParameter: 1, logLevel: 1});
{
logLevel: 0,
ok: 1
}

注意

您还可以获取 MongoDB 组件的日志详细级别。有关详细信息，请参阅db.getLogComponents()。
