Pika

Lightweight probe monitoring — Go + PostgreSQL/SQLite + VictoriaMetrics

English | 简体中文 · Website · Docs

Overview

Pika is a lightweight probe monitoring system. Probes push metrics to the server over WebSocket; VictoriaMetrics stores time-series while PostgreSQL/SQLite stores business data. Beyond monitoring, it provides Linux incident response and baseline checks to surface security risks early.

Features

• 📊 Real-time metrics — CPU / Memory / Disk / Network / GPU / Temperature, with multi-range history
• 🔍 Service checks — HTTP(S) / TCP / ICMP, including cert expiry detection
• 🛡️ Tamper protection — fsnotify watch, immutable attribute patrol, and alerting
• 🔒 Security audit — asset inventory, risk grading (Critical/High/Medium/Low), and audit history
• 🔐 Auth — Basic Auth (bcrypt) / OIDC / GitHub OAuth
• 📦 One-command deploy — Docker Compose, SQLite or PostgreSQL

See Features for details.
