Node.js agent logging settings

Enables or disables agent specific logging.

Defines the level of detail recorded in the agent logs. From least detail to most detail, possible values are fatal, error, warn, info, debug, or trace.

Complete path to the New Relic agent log, including the filename. Defaults to filepath: require('path').join(process.cwd(), 'newrelic_agent.log'). If the agent can't create the log file, then it:

• Logs the New Relic failed to open log file error using console.error.

• Buffers all subsequent log messages in memory.

• When the memory buffer reaches its 128 MiB limit, the agent discards any new log messages and emits the following warning via process.emitWarning: [NRWARN001] NewRelicWarning: Dropping log message, buffer would overflow.

  When creating the log file, the agent sets the file permissions to 0o600 (readable/writable to the owner).

• To write all logging to stdout, set this to stdout.

• To write all logging to stderr, set this to stderr.

  중요

  In agent versions prior to 7.0.0, the agent would shut down the process if it was unable to create this file.

When enabled, the agent logs the payloads it sends to the collector. This data is included in the main log file even when logging level is set to the lowest level.

The agent sends several different types of data to the collector in separate payloads. By default, all of them are included in the log file. This option makes it possible to limit logging only to specific types of data.

Valid values include:

• agent_settings
• analytic_event_data
• connect
• custom_event_data
• error_data
• error_event_data
• metric_data
• preconnect
• shutdown
• span_event_data
• sql_trace_data
• transaction_sample_data
