nexus_semantic_logger

Configures a semantic_logger as required for NexusMods components.

Telemetry

As well as providing a semantic logger, this gem handles datadog telemetry associated with the logging approach:

• logs
• traces
• metrics
  • statsd is automatically attached to datadog runtime metrics and may also be used for custom metrics.
  • ResponseCodeStatsMiddleware is included to capture response code metrics from rack applications

Customise log level per logger

For example, to show debug logging for MySubscriber while having all other logs on info.

# The log level must be set to the lowest level which can be dynamically controlled.
LOG_LEVEL=DEBUG
# The default level for filtered logs.
LOG_NAMES_DEFAULT_LEVEL=INFO
# Per level overrides for filtered logs.
LOG_NAMES_DEBUG=MySubscriber

• Customised log names are available for each level e.g. LOG_NAMES_TRACE
• Log names are matched on prefix.
• Multiple log names are supported via comma separated values.
