When a JuiceFS file system is deployed in production, a critical question arises: how to monitor its operational status in real-time? As it may be providing persistent storage support for critical business applications or container workloads, even minor failures or performance degradation can have significant impacts. JuiceFS publishes its oper ...

Overview Prometheus is an open-source systems monitoring and alerting toolkit originally developed at SoundCloud and now a staple within the Cloud Native Computing Foundation (CNCF). It excels at collecting time-series data using a pull-based model, offering a powerful query language (PromQL) and a multi-dimensional data model. Grafana compleme ...

Prometheus Overview Prometheus is an open-source systems monitoring and alerting toolkit designed for reliability and scalability. Originally developed at SoundCloud and now a CNCF project, it excels at recording numeric time-series data. Core Architecture Prometheus Server: The central component that scrapes and stores time-series data. It op ...

Deploying the Node Exporter To begin collecting system-level metrics, deploy the Node Exporter container. This requires mounting host paths to allow the exporter to read proc and sys filesystem statistics. docker run -d \ --name node-metrics \ --restart unless-stopped \ -p 9100:9100 \ -v "/proc:/host/proc:ro" \ -v "/sys:/host/sys:ro" ...

Setting Up Server Performance Monitoring For effective server performance monitoring, implementing specialized tools becomes essential. Two primary approaches were evaluated: InfluxDB + Telegraf + Grafana Prometheus + Node Exporter + Grafana The InfluxDB documentation appeared inconsistent across versions, making Prometheus the preferred choi ...

Introduction to KubeStateMetrics Kube-state-metrics is a service that listens to the Kubernetes API server and generates metrics about the state of various objects like deployments, nodes, and pods. It transforms these object states into metrics that can be consumed by Prometheus. Key capabilities of kube-state-metrics include: Collecting node ...

Grafana Overview Grafana is an open-source visualization and monitoring platform that enables users to create interactive dashboards and analyze real-time data. The platform supports multiple data sources including Prometheus, Graphite, InfluxDB, Elasticsearch, and MySQL, allowing data to be aggregated and displayed through customizable panels ...

Prometheus has become the de facto standard for metrics collection in modern Java-based microservices. Its pull-based architecture, dimnesional data model, and expressive query language make it ideal for observability in dynamic, containerized environments. Core Architecture Overview Prometheus operates by periodically scraping HTTP endpoints e ...

Metrics Monitoring Overview The application monitoring system combines Metrics.NET, InfluxDB, and Grafana. Metrics.NET collects application metrics through code instrumentation, stores data in InfluxDB (version 1.3.1), and visualizes metrics using Grafana (version 4.0.1). Instrumentation Methods Add Metrics.dll reference to your project and con ...

Containerized Runtime Provisioning Deploying a telemetry architecture for OpenTenBase requires a stable container orchestration environment. Initialize the Docker engine on a CentOS-based host by removing legacy installations, configuring repository sources, and activating the daemon. sudo yum remove -y docker-* sudo yum install -y yum-utils su ...
