When deploying kube-prometheus, your Grafana instance is deployed with a lot of dashboards by default. All those dashboards are comming from upstream projects like kubernetes-mixin, prometheus-mixin and node-exporter-mixin, among others.
In case you find out that you don't need some of them, you can choose to remove those dashboards like in the example below, which removes the alertmanager-overview.json
dashboard.
local kp =
(import 'kube-prometheus/main.libsonnet') +
{
values+:: {
common+: {
namespace: 'monitoring',
},
grafana+: {
dashboards: std.mergePatch(super.dashboards, {
// Add more unwanted dashboards here
'alertmanager-overview.json': null,
}),
},
},
};
{ 'setup/0namespace-namespace': kp.kubePrometheus.namespace } +
{
['setup/prometheus-operator-' + name]: kp.prometheusOperator[name]
for name in std.filter((function(name) name != 'serviceMonitor' && name != 'prometheusRule'), std.objectFields(kp.prometheusOperator))
} +
// serviceMonitor and prometheusRule are separated so that they can be created after the CRDs are ready
{ 'prometheus-operator-serviceMonitor': kp.prometheusOperator.serviceMonitor } +
{ 'prometheus-operator-prometheusRule': kp.prometheusOperator.prometheusRule } +
{ 'kube-prometheus-prometheusRule': kp.kubePrometheus.prometheusRule } +
{ ['alertmanager-' + name]: kp.alertmanager[name] for name in std.objectFields(kp.alertmanager) } +
{ ['blackbox-exporter-' + name]: kp.blackboxExporter[name] for name in std.objectFields(kp.blackboxExporter) } +
{ ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) } +
{ ['kube-state-metrics-' + name]: kp.kubeStateMetrics[name] for name in std.objectFields(kp.kubeStateMetrics) } +
{ ['kubernetes-' + name]: kp.kubernetesControlPlane[name] for name in std.objectFields(kp.kubernetesControlPlane) }
{ ['node-exporter-' + name]: kp.nodeExporter[name] for name in std.objectFields(kp.nodeExporter) } +
{ ['prometheus-' + name]: kp.prometheus[name] for name in std.objectFields(kp.prometheus) } +
{ ['prometheus-adapter-' + name]: kp.prometheusAdapter[name] for name in std.objectFields(kp.prometheusAdapter) }
