+## Monitoring
+For a monitoring openDesk has an optional deployment of Kubernetes Resources for the usage with [Prometheus Operator](https://prometheus-operator.dev).
+
+There is an easy all in one Monitoring helm-chart
+[kube-prometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
+which also deployes an Grafana as sub-helmchart.
+
+
+### Metrics (pod- and serviceMonitor)
+To deploy podMonitor and serviceMonitor, enable it by:
+```yaml
+prometheus:
+  monitor:
+    enabled: true
+```
+
+### Alerts (prometheusRules)
+Some helm-charts provide a default set of prometheusRules for alerting
+To deploy prometheusRules (alerts), enable it by:
+```yaml
+prometheus:
+  rules:
+    enabled: true
+```
+
+### Non default Prometheus setup
+An Prometheus Instance (deployed by Prometheus-Operator)
+search for Kubernetes-Resources by his labels
+on kube-prometheus-stack the default-value are "release=kube-prometheus-stack".
+
+If you use a different Prometheus-Setup, maybe you like to adjust the labels:
+```yaml
+prometheus:
+  monitor:
+    labels:
+      release: "kube-prometheus-stack"
+  rules:
+    labels:
+      release: "kube-prometheus-stack"
+```
+
+### Dashboards for Grafana
+The default Grafana helm-chart is able to collect this with an pre installed sidecar
+
+Deploy optional ConfigMaps with grafana dashboards.
+```yaml
+grafana:
+  dashboards:
+    enabled: true
+```
+
+
+#### Non default Grafana setup
+The pre installed sidecar of grafana search for ConfigMaps and Secrets by his labels
+on default value  is "grafana_dashboard=1".
+
+If you use a different setup, maybe you like to adjust the labels:
+```yaml
+grafana:
+  dashboards:
+    labels:
+      grafana_dashboard: "1"
+```
+
+#### Put Dashboards in Grafana folder
+usefull for putting dashboards in folder
+https://github.com/grafana/helm-charts/tree/grafana-6.58.6/charts/grafana#configuration
+if in grafana helmchart `sidecar.dashboards.folderAnnotation` and `sidecar.dashboards.provider.foldersFromFilesStructure` set
+or in [kube-prometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack):
+```yaml
+grafana:
+  sidecar:
+    dashboards:
+      folderAnnotation: "grafana-dashboard-folder"
+      provider:
+         foldersFromFilesStructure: true
+```
+
+Afterward you could configure openDesk with this helmfile to use the directory e.g. "openDesk":
+```yaml
+grafana:
+  dashboards:
+    annotations:
+      "grafana-dashboard-folder": "openDesk"
+```
