The pve-exporter is scraped via all 3 PVE nodes and each scrape returns the
full cluster view, so every series exists in triplicate. All stat counts were
3x too high (Online Nodes showed 39 instead of 3) and every bargauge/table
row appeared three times. Wrap all queries in max by (id) / count by (id).
- Online Nodes: count unique node/* ids with pve_up==1 (was 39, now 3);
threshold green at 3 so a lost node turns red
- Total VMs: count unique qemu guests excluding templates (was 12, now 3)
- Total LXC: count unique ids (was 9, now 3)
- Running Guests: pve_guest_info has no status label in this exporter
version (panel showed No data); derive from pve_up==1 per guest instead
- Node CPU/Memory bargauges + timeseries: filter to id=~"node/.*" — they
showed every guest (mostly lxc rows), not nodes
- Guest Status table: dedupe rows, add Status column from pve_up (color
mapped 1=Running/0=Stopped), drop useless Info column, migrate
custom.displayMode -> custom.cellOptions (schemaVersion 38 skips the
Grafana 10 migration, so gradient gauges/color background were silently
ignored)
- Node Disk I/O -> Guest Disk I/O: pve_disk_read/write metrics only exist
for qemu/lxc guests, never node/* (panel was permanently No data); use
the *_total counters with rate()
