Back
appender (clj)
(source)function
(appender {:keys [logger-provider]})
Returns a `com.github.steffan-westcott/clj-otel-api` appender.
For use WITH OpenTelemetry Java Agent-
Setup a Java Agent appender, e.g.:
(otlp/appender {:logger-provider (.getLogsBridge (GlobalOpenTelemetry/get))})
For agent v1.x: enable the logs exporter with `OTEL_LOGS_EXPORTER=otlp`.
For agent v2.x: the logs exporter should be enabled by default [1].
For use WITHOUT OpenTelemetry Java Agent-
Setup an "autoconfiguration" appender, e.g.:
(otlp/appender
{:logger-provider
(.getSdkLoggerProvider
(.getOpenTelemetrySdk
(.build (AutoConfiguredOpenTelemetrySdk/builder))))})
You'll need the following on your classpath:
`io.opentelemetry/opentelemetry-sdk-extension-autoconfigure`,
`io.opentelemetry/opentelemetry-exporter-otlp`.
If you already have an instance of `GlobalOpenTelemetry` (e.g. created
by agent), you'll need to prevent setting the newly-created SDK as the
global default:
(.build
(doto (AutoConfiguredOpenTelemetrySdk/builder)
(.setResultAsGlobal false)))
