Duplicate series with two Raspberry Pis about grafana-dashboards

[jorti]

I also see this error in my x86_64 servers.

I see the same thing on my x86 servers as well.

I'm having similar issue with another series.
I'm monitoring 2 devices, a rpi and an odroid, both seem to report a thermal_thermal_zone0 leading to duplicate series.
The error is reported by Hardware temperature monitor panel.

found duplicate series for the match group {chip="thermal_thermal_zone0"} on the right hand-side of the operation: [{__name__="node_hwmon_chip_names", chip="thermal_thermal_zone0", chip_name="cpu_thermal", instance="pi.hole:9100", job="node"}, {__name__="node_hwmon_chip_names", chip="thermal_thermal_zone0", chip_name="acpitz", instance="odroid.home:9100", job="node"}];many-to-many matching not allowed: matching labels must be unique on one side

Same for my nas and gateway - both have an nvme0 device and that's enough to trip it over

Huh, it seems like the dashboard listed on Grafana site is not the latest available version. If you import https://github.com/rfmoz/grafana-dashboards/blob/master/prometheus/node-exporter-full.json to Grafana, the issue is resolved
