Unable create Summary

[ArkadySh]

Can you provide working example how create summary family ?

I tried to do something like this :

struct SummaryWithQuantiles {
		prometheus::Family<prometheus::Summary> family;
		std::vector<double> quantiles;

		// Constructor to initialize the family member
		SummaryWithQuantiles(const prometheus::Family<prometheus::Summary>& fam, const std::vector<double>& q)
			: family(fam), quantiles(q) {}
	};

	void PrometheusInterface::CreateSummary(const std::string& name, const std::string& help, const std::vector<double>& quantiles) {
		const std::chrono::milliseconds max_age(3600000);  // 1 hour
		const int age_buckets = 5;

		// Create the summary family
		auto summary_family = prometheus::BuildSummary()
			.Name(name)
			.Help(help)
			.MaxAge(max_age)
			.AgeBuckets(age_buckets)
			.Register(*mRegisterShPtr);

		// Create a custom structure to hold the summary family and quantiles
		SummaryWithQuantiles summaryWithQuantiles(summary_family, quantiles);

		// Store the summary with quantiles in the map
		mSummaries[name] = summaryWithQuantiles;
	}
		void PrometheusInterface::ObserveSummary(const std::string& name, double value, const std::map<std::string, std::string>& labels) {
		if (mSummaries.find(name) != mSummaries.end()) {
			auto& summaryWithQuantiles = mSummaries[name];
			for (double quantile : summaryWithQuantiles.quantiles) {
				summaryWithQuantiles.family.Add(labels).Quantile(quantile).Observe(value);
			}
		}
		else {
			LOG4CXX_ERROR(log4cxx::Logger::getLogger("PrometheusInterface"), Format("Summary metric %s was not created before, so it will not be observed!", name.c_str()));
		}
	}

but it is not compiled .

There is a bug in summary.h:

Class Summary has to be declared as "class Summary : public Metric", not "class Summary : Metric".
