Useful extensions for using swift-log together with Clairvoyant.
Clairvoyant can be used as a logging backend for swift-log, so that all logs are made available as String metrics.
To forward logs as metrics, add a dependency for ClairvoyantLogging and import the required module:
import Clairvoyant
import ClairvoyantLoggingNow, simply set an observer as the backend:
let observer = MetricObserver(...)
let logging = MetricsLogging(observer: observer)
LoggingSystem.bootstrap(logging.backend)Each logging entry will then be timestamped and added to a metric with the same ID as the logger label.
let logger = Logger(label: "my.log")
logger.info("It works!")The logging metrics are made available over the API in the same way as other metrics, and can also be accessed directly.
let metric = observer.getMetric(id: "my.log", type: String.self)It's possible to change the logging format by setting the loggingFormat property on MetricLogging before creating a logger.
The property applies to each new logger, but changes are not propagated to existing ones.
logging.outputFormat = .full
