OTEL Metrics listing

[deebsr]

I have setup my PVE clusters to send to an OTEL endpoint ( in my case Grafana Alloy and into Mimir ).
I'm trying to build out the Grafana dashboard panels but I'm having issues with figuring out what are the metrics to query.
Some are obvious like CPU usage ( proxmox_node_cpustat_cpu_percent ) or RAM usage ( proxmox_node_memory_memused_bytes ). but I'm trying to figure out how to get IO wait in a panel but there seems to be numerous metrics that sounds like this but are not.

I see

• proxmox_node_cpustat_wait_seconds_total
• proxmox_node_cpustat_iowait_seconds_total
• proxmox_node_cpustat_sum_ratio
• proxmox_node_cpustat_system_seconds_total

What are these values mean? what unit of measurement are they? Is there anywhere that has explanation on what all these metrics are and what they represent?
Is IO wait something that would need to be calculated from a bunch of different metrics?

thanks for your help
