Practice Test - Monitor Cluster Components

Solutions to practice test - monitor cluster components

We have deployed a few PODs running workloads. Inspect it.
```
kubectl get pods
```
Let us deploy metrics-server to monitor the PODs and Nodes. Pull the git repository for the deployment files.
```
git clone https://github.com/kodekloudhub/kubernetes-metrics-server.git
```
Deploy the metrics-server by creating all the components downloaded.

Run the ‘kubectl create -f .’ command from within the downloaded repository.
```
cd kubernetes-metrics-server
kubectl create -f .
```
It takes a few minutes for the metrics server to start gathering data.

Run the kubectl top node command and wait for a valid output.
```
kubectl top node
```
Identify the node that consumes the most CPU(cores).

Run the kubectl top node command
```
kubectl top node
```
Examine the CPU(cores) column of the output to get the answer.
Identify the node that consumes the most Memory(bytes).
Run the `kubectl top node` command
```
$ kubectl top node
```
Examine the MEMORY(bytes) column of the output to get the answer.
Identify the POD that consumes the most Memory(bytes).

Run the kubectl top pod command
```
kubectl top pod
```
Examine the MEMORY(bytes) column of the output to get the answer.
Identify the POD that consumes the least CPU(cores).

Run the kubectl top pod command
```
kubectl top pod
```
Examine the CPU(cores) column of the output to get the answer.
