Log Format

CLI REPL listens to a few events via a message bus that are then logged to user's local log file in ~/.mongodb/mongosh/ in ndjson format using pino.

bus.on('mongosh:connect', connectEvent)

Where connectionInfo is an object with the following interface:

interface ConnectEvent {
  driverUri: string;
}

Used to log and send telemetry about connection information. Sensitive information is stripped beforehand.

Example:

bus.emit('mongosh:connect', {
  driverUri: 'mongodb://192.168.0.5:9999/ships',
});

bus.on('mongosh:new-user', telemetryUserIdentity, enableTelemetry)

Where telemetryUserIdentity is userId and anonymousId which are both a BSON ObjectID. And enableTelemetry is a boolean flag. This is used internally to update telemetry preferences.

Example:

bus.emit(
  'mongosh:new-user',
  { userId: '12394dfjvnaw3uw3erdf', anonymousId: '12394dfjvnaw3uw3erdf' },
  true
);

bus.on('mongosh:update-user', telemetryUserIdentity, enableTelemetry)

Where telemetryUserIdentity is userId and anonymousId which are both a BSON ObjectID. And enableTelemetry is a boolean flag. This is used internally to update telemetry preferences.

Example:

bus.emit(
  'mongosh:update-user',
  { userId: '12394dfjvnaw3uw3erdf', anonymousId: null },
  false
);

bus.on('mongosh:error', error)

Where error is an Error Object. Used to log and send telemetry about errors that are thrown.

Example:

bus.emit('mongosh:error', new Error('Unable to show collections'));

bus.on('mongosh:rewritten-async-input', inputInfo)

Used for internal debugging of async-rewriter. inputInfo is an object with the following interface:

interface AsyncRewriterEvent {
  original: string;
  rewritten: string;
}

Example:

bus.emit('mongosh:rewritten-async-input', {
  original: 'db.coll.find().forEach()',
  rewritten: 'await db.coll.find().forEach();',
});

bus.on('mongosh:use', args)

Used for recording information about use. args has the following interface:

interface UseEvent {
  db: string;
}

Example:

bus.emit('mongosh:use', { db: 'cats' });

bus.on('mongosh:show', args)

Used for recording information about show command. args has the following interface:

interface ShowEvent {
  method: string;
}

Example:

bus.emit('mongosh:show', { method: 'dbs' });

bus.on('mongosh:it')

Used for recording when it command was called.

Example:

bus.emit('mongosh:it');

bus.on('mongosh:api-call', args)

Used for recording information when API calls are made. args has the following interface:

interface ApiEvent {
  method?: string;
  class?: string;
  db?: string;
  coll?: string;
  arguments?: ApiEventArguments;
}

interface ApiEventArguments {
  pipeline?: any[];
  query?: object;
  options?: object;
  filter?: object;
}

arguments may contain information about the API call. As a rule, we don't emit information containing documents coming from API calls such as db.coll.insert() or db.coll.bulkWrite() to keep cleaner logs.

aggregate Event Example:

this.messageBus.emit('mongosh:api-call', {
  method: 'aggregate',
  class: 'Collection',
  db,
  coll,
  arguments: { options, pipeline },
});

runCommand Event Example:

this.messageBus.emit('mongosh:api-call', {
  method: 'runCommand',
  class: 'Database',
  db,
  arguments: { cmd },
});

createIndex Event Example:

this.messageBus.emit('mongosh:api-call', {
  method: 'createIndex',
  class: 'Collection',
  db,
  coll,
  arguments: { keys, options },
});
