Subject: [PATCH datacenter-manager v4 11/12] ui: node status: add RRD graphs for PDM host metrics
Date: Wed, 15 Apr 2026 15:20:12 +0200 [thread overview]
Message-ID: <20260415132013.440581-12-l.wagner@proxmox.com> (raw)
In-Reply-To: <20260415132013.440581-1-l.wagner@proxmox.com>
This adds RRD graphs in the existing node status panel. We add graphs
for
- CPU/IOWait
- Load-Avg
- Memory usage
- Network utilization
- Pressure (CPU, memory, IO)
