 The following examples serve as individual configurations and as inspiration for how deployment problems can be solved.
 
-#### Avoid CPU throttling by defining a CPU limit
-
-If the application is deployed with a CPU resource limit, Prometheus may throw a CPU throttling warning for the
-application. This has more or less to do with the fact that the application finds the number of CPUs of the host, but
-cannot use the available CPU time to perform computing operations.
-
-The application must be informed that despite several CPUs only a part (limit) of the available computing time is
-available. As this is a Golang application, this can be implemented using `GOMAXPROCS`. The following example is one way
-of defining `GOMAXPROCS` automatically based on the defined CPU limit like `1000m`. Please keep in mind, that the CFS
-rate of `100ms` - default on each kubernetes node, is also very important to avoid CPU throttling.
-
-Further information about this topic can be found [here](https://kanishk.io/posts/cpu-throttling-in-containerized-go-apps/).
-
-> [!NOTE]
-> The environment variable `GOMAXPROCS` is set automatically, when a CPU limit is defined. An explicit configuration is
-> not anymore required.
->
-> Please take care the a CPU limit < `1000m` can also lead to CPU throttling. Please read the linked documentation carefully.

-helm install prometheus-postgres-exporter prometheus-exporters/prometheus-postgres-exporter \

-### Network policies
-
-Network policies can only take effect, when the used CNI plugin support network policies. The chart supports no custom
-network policy implementation of CNI plugins. It's support only the official API resource of `networking.k8s.io/v1`.
-
-The object networkPolicies can contains multiple networkPolicy definitions. There is currently only one example
-predefined - it's named `default`. Further networkPolicy rules can easy be added by defining additional objects. For example:
-
-> [!NOTE]
-> The structure of each custom network policy must be equal like that of default. For this reason don't forget to define
-> `annotations`, `labels` and the other properties as well.
-
-```yaml
-networkPolicies:
-  enabled: false
-  default: {}
-  my-custom-network-policy: {}
-```
-
-The example below is an excerpt of the `values.yaml` file. The network policy `default` contains ingress rules to allow
-incoming traffic from Prometheus. Additionally two egress rules are defined, to allow the application outgoing access to
-the internal running DNS server `core-dns` and the external running postgres database listen on `10.14.243.12`.
-
-> [!IMPORTANT]
-> Please keep in mind, that the namespace and pod selector labels can be different from environment to environment. For
-> this reason, there is are not default network policy rules defined.
