Thanos is a CNCF cloud native monitoring tool that provides a highly available and scalable extension to the Prometheus ecosystem. It functions as a global query engine, a long-term storage system, and a metric downsampler. The project enables a unified interface to aggregate and query metrics across multiple distributed clusters from a single view. It maintains historical data beyond local retention limits by persisting time-series metrics in object storage and eliminates data gaps by merging metrics from redundant server pairs. The system includes capabilities for reducing the resolution o
Creates lower-resolution versions of historical metrics to accelerate queries over massive datasets.
This project is a comprehensive library of practical Python code examples and patterns. It provides a collection of scripts and snippets designed to demonstrate a wide range of programming tasks, from basic syntax to advanced implementation patterns. The repository focuses on several core domains, including the implementation of concurrency and multithreading examples, data analysis snippets for cleaning and manipulating tabular data, and various data visualization examples. It also covers automation scripts for file system management and a variety of general programming patterns. Additional
Provides a tool to aggregate high-frequency time series data into lower-frequency intervals.
GreptimeDB is a distributed, open-source time-series database built for unified observability. It stores and queries metrics, logs, and traces together in a single columnar engine, supporting both SQL and PromQL for analysis. The database is designed as a Kubernetes-native operator with a decoupled compute and storage architecture, enabling horizontal scaling and multi-region deployment. What distinguishes GreptimeDB is its role as a multi-protocol ingestion gateway, accepting data through OpenTelemetry, Prometheus Remote Write, InfluxDB, Loki, Elasticsearch, Kafka, and MQTT protocols without
Reduces data volume by applying operations like average pooling to stored time-series data for efficient analysis.
OpenTSDB هي قاعدة بيانات موزعة للسلاسل الزمنية ومحرك مقاييس مصمم لتخزين وإدارة أحجام هائلة من مقاييس النظام عالية التباين. تعمل كمخزن بيانات ومنصة تحليلات تتيح استيعاب المقاييس على نطاق واسع ومراقبة أداء البنية التحتية عبر مجموعة موزعة. يتميز النظام بتجريد تخزين موزع يدعم خلفيات متعددة مثل HBase و Cassandra و Google Bigtable. يستخدم شجرة مقاييس هرمية لتنظيم السلاسل الزمنية ويستخدم فهرسة المعرفات الرقمية لتقليل بصمات التخزين وتسريع عمليات البحث للمقاييس الموسومة. يغطي المشروع مجالات قدرات واسعة بما في ذلك تحليل بيانات السلاسل الزمنية مع حسابات النسبة المئوية الموزعة وأخذ العينات الفرعية، بالإضافة إلى إدارة شاملة للبيانات الوصفية. يوفر دمج واجهة برمجة التطبيقات لاستيعاب البيانات والاستعلام، وتخزين مؤقت خارج الكومة (Off-heap) لتحسين الأداء، وأدوات لتدقيق سلامة البيانات وتحليل الشذوذ. يتم إدارة النظام عبر واجهة سطر أوامر لإدارة قاعدة البيانات ومزامنة شجرة المقاييس.
