alertmanager vs Glances
Side-by-side comparison of features, pricing, ratings, and alternatives.
Alertmanager is a tool that handles alerts sent by Prometheus, a monitoring system and time series database. It takes care of deduplicating, grouping, and routing them to the correct receiver integration such as email, PagerDuty, or Slack. It also takes care of silencing and inhibition of alerts.
Glances is an open‑source, cross‑platform monitoring tool that provides a concise, real‑time view of system resources such as CPU, memory, disk I/O, network, and processes. It runs on Linux, Windows, macOS and can be accessed via a web interface, making it ideal for both local and remote monitoring. Designed for system administrators and DevOps teams, Glances aggregates metrics into a single dashboard, supports customizable alerts, and integrates with scripts or APIs for automated workflows. Its lightweight design ensures minimal overhead while delivering comprehensive performance insights.
