Service level indicators

Sloth is a plugin-extensible reliability engine that translates concise service level objective specifications into production-ready alerting rules and monitoring dashboards. It automates the generation of multi-window, multi-burn-rate alert rules alongside visual dashboards for metrics platforms like Prometheus and Grafana, establishing uniform monitoring outputs from simple definition formats. The tool provides static definition validation to inspect service configuration files for semantic and structural errors prior to rule generation, enforcing correctness early. It supports an abstract

This library is an instrumentation framework for Rust applications designed to record and expose performance metrics compatible with the Prometheus monitoring system. It provides tools for tracking custom application state and host-level system resource usage, such as CPU and memory consumption, to ensure operational visibility. The framework is built for high-throughput environments, utilizing thread-local storage and atomic operations to minimize synchronization overhead during data collection. It leverages compile-time metric definitions and static typing to eliminate dynamic lookups, ensu

This is a Prometheus Python client library used for instrumenting Python applications. It provides the tools necessary to record counters, gauges, and histograms within a process to monitor application health and expose that data as a Prometheus exposition format provider. The library enables cloud native observability by allowing developers to define custom telemetry and track internal application events. It transforms internal application data into a standardized text format required by Prometheus scrapers for collection. The project covers a variety of monitoring and observability capabil

Giropops-monitoring is an integrated observability platform designed to monitor the health and performance of containerized infrastructure. It provides a containerized suite that orchestrates the deployment of monitoring services, enabling the collection, storage, and visualization of system metrics across distributed environments. The platform utilizes a pull-based approach to scrape performance data from target nodes, storing these metrics in a specialized time-series database for long-term analysis. Users can inspect this data through interactive, web-based dashboards that render real-time

This library provides a framework for instrumenting Java applications to track performance and system-level statistics. It enables the definition and collection of metrics such as counters, gauges, and histograms, while automatically capturing runtime health indicators like memory usage, thread activity, and garbage collection performance. The project distinguishes itself through a registry-based aggregation model that decouples metric recording from data exposition. It supports thread-safe atomic instrumentation for high-frequency data collection and offers flexible export mechanisms, includ

Healthchecks is a heartbeat monitoring service and cron job monitoring tool designed to track the execution and success of scheduled tasks and systemd timers. It functions as a dead man switch, alerting users when expected periodic signals from remote processes fail to arrive. The system accepts health signals via HTTP and SMTP, allowing it to track infrastructure heartbeats from sources ranging from CI/CD workflows to network routers. It distinguishes itself by supporting the capture of diagnostic data, including exit codes and execution logs, and by calculating the duration between start an

Alertmanager is a monitoring notification gateway and routing service that deduplicates, groups, and directs alerts to the correct receivers. It functions as a central manager for Prometheus alerts, using a hierarchical routing tree and label-based matchers to dispatch notifications to external services. The system employs a peer-to-peer mesh network to coordinate multiple instances in a high availability cluster, ensuring continuous alert processing. It features a dedicated inhibition engine and grouping mechanisms to reduce notification noise by suppressing redundant alerts when related iss

Fourkeys is a software delivery analytics platform designed to track, calculate, and display core DevOps performance indicators and metrics. It ingests development and deployment events from version control, continuous integration, incident management, and deployment systems through authorized webhook endpoints, custom data parsers, and pluggable adapters. The platform processes incoming events using serverless functions and populates a data warehouse to measure engineering speed and reliability. The system calculates key performance measurements including deployment frequency, lead time for

Scrutiny is a distributed hardware monitoring system and predictive drive failure analyzer. It provides a centralized management platform and web-based dashboard for tracking hard drive health and S.M.A.R.T. metrics across multiple remote servers. The system functions as a S.M.A.R.T. alerting gateway and storage health trend visualizer. It estimates hardware risk by comparing drive attributes against real-world failure thresholds and records historical data to identify gradual degradation patterns that may not trigger immediate alerts. Capabilities include distributed data collection via rem

Coroot is an observability platform and Kubernetes performance monitor that utilizes eBPF to automatically collect metrics, logs, and traces without requiring manual code instrumentation. It functions as an OpenTelemetry trace analyzer and an LLM observability gateway, exposing system health data to large language models through the Model Context Protocol. The platform differentiates itself by combining automated root cause analysis and AI-driven diagnostics to investigate performance regressions. It also includes a cloud cost monitoring tool that attributes infrastructure spending to specifi

Zabbix is an enterprise-grade open-source platform for monitoring IT infrastructure, networks, and applications. It provides real-time metrics, alerts, and dashboards, enabling organizations to track performance and availability across their entire technology stack. The platform collects metrics from virtually any source, including agents, agentless protocols, APIs, containers, databases, and cloud platforms, without requiring custom scripting. It automatically discovers IT resources by scanning network ranges and cloud environments, then applies pre-built templates for immediate monitoring.
