Customize node-mixin

[chg-dio]

Hi, I try since a while to change one config value of the node-exporter mixin shipped with the kube-prometheus install but am not able to do so.

As I found it in several documentations I tried something like the code in the first example in different versions but wasn't able to get any result. The objects are also empty, for when I try to print them they don't have any output (second example).

local mem = import "./vendor/node-mixin/mixin.libsonnet";

local memory = mem {
	_config+:: {
		memoryHighUtilizationThreshold: 50,
	},
};

local mem = import "vendor/node-mixin/mixin.libsonnet";

std.trace("obj content: %s" % [mem], mem) +

local memory = mem {
	_config+:: {
		memoryHighUtilizationThreshold: 50,
	},
};

std.trace("obj content: %s" % [memory], memory) +

I also tried to overwrite the value like I did for the components mixin rules - that was working and is documented here: developing-prometheus-rules-and-grafana-dashboards.md#changing-default-rules - unfortunately it doesn't work for the node-exporter mixin.

Any help how to customize the node-exporter config values would be really appreciated.

The issue was related to false naming of the rule. https://github.com/prometheus-operator/kube-prometheus/blob/main/docs/customizations/developing-prometheus-rules-and-grafana-dashboards.md#changing-default-rules is working for the node-exporter mixins also.
