Netdata real-time infrastructure monitoring on Ubuntu 24.04 LTS by cloudimg. Thousands of per-second metrics (CPU, memory, disks, network, applications) auto-discovered into a live dashboard that updates every second, with health alerting built in. The agent is bound to loopback and fronted by nginx on port 80 with a per-VM HTTP Basic Auth password generated on first boot; Netdata Cloud phone-home and anonymous statistics are disabled by default. Metrics database on a dedicated Azure data disk. GPL-3.0 licensed.
Netdata is an open source, real-time infrastructure monitoring agent. It auto-discovers and collects thousands of per-second metrics from the host - CPU, memory, disks, filesystems, network interfaces, systemd services, running applications and containers - and renders them in a rich, interactive dashboard that updates every second, with hundreds of pre-configured health alarms. The cloudimg image installs the pinned Netdata stable 2.10.3 as a native package running under systemd, then locks it down for a marketplace appliance. The Netdata agent is bound to loopback 127.0.0.1:19999 so its normally-open dashboard is never exposed to the network directly, and an nginx reverse proxy on port 80 adds a per-VM HTTP Basic Auth gate in front of it, with the live-update stream proxied and an unauthenticated /healthz endpoint for Azure Load Balancer probes. Netdata Cloud phone-home and anonymous statistics are disabled by default, so this VM monitors itself privately out of the box. A unique dashboard password is generated on the first boot of every VM, and the Netdata dbengine metrics database, the registry and the per-VM machine identity live on a dedicated 20 GiB Azure data disk captured into the image and re-provisioned on every VM. Add more nodes or connect Netdata Cloud (optional, off by default) when you are ready. Backed by 24/7 cloudimg support.
