Example 1 with MetricReporterFactory

use of org.apache.flink.metrics.reporter.MetricReporterFactory in project flink by apache.

the class ReporterSetup method setupReporters.

private static List<ReporterSetup> setupReporters(Map<String, MetricReporterFactory> reporterFactories, List<Tuple2<String, Configuration>> reporterConfigurations) {
    List<ReporterSetup> reporterSetups = new ArrayList<>(reporterConfigurations.size());
    for (Tuple2<String, Configuration> reporterConfiguration : reporterConfigurations) {

        Configuration reporterConfig = reporterConfiguration.f1;
        try {
            Optional<MetricReporter> metricReporterOptional = loadReporter(reporterName, reporterConfig, reporterFactories);
            // massage user variables keys into scope format for parity to variable exclusion
            Map<String, String> additionalVariables = reporterConfig.get(ADDITIONAL_VARIABLES).entrySet().stream().collect(Collectors.toMap(e -> ScopeFormat.asVariable(e.getKey()), Entry::getValue));
