ClassDescriptionAbstractVeniceAggStats<T extends AbstractVeniceStats>AbstractVeniceAggStoreStats<T extends AbstractVeniceStats>This class is an aggregate place that keeps stats objects for multiple stores.Right now, Venice SN only reports aggregated metrics for RocksDB.
AggServerHttpRequestStatsis the aggregate statistics forServerHttpRequestStatscorresponding to the type of requests defined inRequestType.AggServerQuotaUsageStatsis the aggregate statistics forServerQuotaUsageStatswhich measures requests and quota rejections of each store.BackupVersionOptimizationServiceStatsrecord the statistics for the database optimization done by theBackupVersionOptimizationServiceincluding both successes and failures.DiskHealthStatsmeasures the disk health conditions based on the periodic tests ran by theDiskHealthCheckService.Deprecated.LeakedResourceCleanerStatsrecords the occurrences of store resources get removed byLeakedResourceCleaner.This metric class is to optimize for high write throughput, low read throughput measurement use case instead of real-time measurement.CheckTickerTypeto find more details about RocksDB metrics.ServerHttpRequestStatscontains a list of counters in order to mainly measure the performance of handling requests from Routers.For measuring quota requests and rejections for a given store.This enum tracks the error codes that we use to report anomalies in metrics.StatsSupplier<T extends AbstractVeniceStats>Utils for venice metricsGenerate a ratio stat that is based on two arbitraryRate.Generate a ratio stat that is based on two arbitraryMeasurableStat.Stats used to collect the usage of a thread pool including: 1.Simple class that spins JVM platform stats into Venice stats.Configuration for metrics emitted by Venice: Holds OpenTelemetry as well as Tehuti configs
Configs starting with "otel.venice." are venice specific configs for OpenTelemetry metrics
other configs starting with "otel.exporter." are generic OpenTelemetry exporter configs but are parsed in this class and used setters to configure otel exporter.Repository to hold both tehuti and OpenTelemetry metrics.A host level metric to track number of active venice writers.The stats keep track of ZK Client status changes.
