### Question:
TelemetryCommonConfigService { @VisibleForTesting void resolveLogPathReferences(Telemetry telemetry, List<VmLog> logs) { Map<String, Object> fluentAttributes = telemetry.getFluentAttributes(); if (CollectionUtils.isNotEmpty(logs)) { Properties props = new Properties(); props.setProperty(SERVER_LOG_FOLDER_PREFIX, fluentAttributes.getOrDefault(SERVER_LOG_FOLDER_PREFIX, LOG_FOLDER_DEFAULT).toString()); props.setProperty(AGENT_LOG_FOLDER_PREFIX, fluentAttributes.getOrDefault(AGENT_LOG_FOLDER_PREFIX, LOG_FOLDER_DEFAULT).toString()); props.setProperty(SERVICE_LOG_FOLDER_PREFIX, fluentAttributes.getOrDefault(SERVICE_LOG_FOLDER_PREFIX, LOG_FOLDER_DEFAULT).toString()); PropertyPlaceholderHelper propertyPlaceholderHelper = new PropertyPlaceholderHelper("${", "}"); for (VmLog log : logs) { String resolvedPath = propertyPlaceholderHelper.replacePlaceholders(log.getPath(), props); log.setPath(resolvedPath); } } } TelemetryCommonConfigService(AnonymizationRuleResolver anonymizationRuleResolver,
            @Value("${info.app.version:}") String version); TelemetryCommonConfigView createTelemetryCommonConfigs(Telemetry telemetry, List<VmLog> logs,
            String clusterType, String clusterCrn, String clusterName, String clusterOwner, String platform);  }### Answer:
