beforeSendLog

To filter logs, or update them before they are sent to Sentry, you can use the getLogs().beforeSend option.

import io.sentry.Sentry;

Sentry.init(options -> {
  options.setDsn("___PUBLIC_DSN___");
  options.getLogs().setBeforeSend((logEvent) -> {
    // Modify the event here:
    logEvent.setBody("new message body");
    return logEvent;
  });
});

import io.sentry.Sentry
import io.sentry.SentryOptions.Logs.BeforeSendLogCallback

Sentry.init { options ->
  options.dsn = "___PUBLIC_DSN___"
  options.logs.beforeSend = BeforeSendLogCallback { logEvent ->
    // Modify the event here:
    logEvent.body = "new message body"
    return logEvent;
  }
}

The beforeSend function receives a log object, and should return the log object if you want it to be sent to Sentry, or null if you want to discard it.

contextTags

You can use the contextTags option to include specific properties from the Mapped Diagnostic Context (MDC) as attributes on log entries sent to Sentry.

For detailed configuration examples, see the Advanced Usage documentation for your logging framework.
