Monitoring

Overview

Astradial uses two monitoring layers:

  • Netdata -- Real-time system metrics, alerts, and dashboards
  • Upptime -- Public status page with uptime tracking via GitHub Actions

Netdata

Installations

Location URL Notes
NUC (on-premise) http://192.168.0.13:19999 Installed with --static-only to avoid CPU overheat during build
Cloud server http://89.116.31.109:19999 Standard installation

Both instances are connected to Netdata Cloud under the hari-space-company space.

Monitored Metrics

  • CPU usage and temperature
  • RAM usage
  • Disk usage and I/O
  • Network throughput

Alerts

Alerts are configured in Netdata Cloud with email and mobile push notifications:

Alert Trigger Severity
Node unreachable Agent stops reporting Critical
CPU temperature high Sustained high temp Warning
Disk full Disk usage above threshold Critical
RAM exhausted Memory usage above threshold Warning

NUC Static-Only Install

The NUC uses --static-only Netdata installation. Building Netdata from source caused the NUC to overheat and crash. See Troubleshooting - Error 11.

Upptime

Upptime provides a public-facing status page powered by GitHub Actions. It checks service availability every 5 minutes and publishes results to a static site.

Property Value
Repository astradial/upptime
Status Page status.astradial.com
Config File .upptimerc.yml
Deployment GitHub Pages from gh-pages branch

Monitored Services

Upptime checks 5 services every 5 minutes.

GitHub Actions Workflows

Workflow Schedule Purpose
Uptime CI Every 5 minutes Check service availability
Response Time CI Every 5 minutes Measure response times
Graphs CI Every 5 minutes Generate uptime graphs
Summary CI Daily Generate daily summary
Static Site CI Daily Build and deploy status page

Deployment

The status page is built as a static site and deployed to GitHub Pages using the peaceiris/actions-gh-pages action, which pushes to the gh-pages branch.

# Deployment step in workflow
- uses: peaceiris/actions-gh-pages@v3
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    publish_dir: ./build

Why peaceiris/actions-gh-pages

Without this action, the site builds but never deploys to GitHub Pages, resulting in a 404. See Troubleshooting - Error 12.
