After doing some test,
if I understand, the node static infos max-mem, max-cpu are only used
to have percents to be able to compare each node.
and the nodeusage is compute with the sum of static mem/cpu of the
services running on this node.
But I really don't see where it's node in the rust code ?
I see a
+impl StaticNodeUsage {
+ /// Add usage of `service` to the node's usage.
+ pub fn add_service_usage(&mut self, service: &StaticServiceUsage)
{
+ self.cpu = add_cpu_usage(self.cpu, self.maxcpu as f64,
service.maxcpu);
+ self.mem += service.maxmem;
+ }
+}
But I don't see where it's called ?
(BTW, I don't see the repo in proxmox git ?)
