## 2.4 - Checking application resource usage
|
||||
|
||||
Another essential element of supporting applications on OpenShift is understanding what resources the application is consuming, for example cpu, memory, network bandwidth and storage io.
|
||||
|
||||
OpenShift includes built in support for reviewing application resource usage. Let's take a look at that now.
|
||||
|
||||
In the **Developer** perspective, open the **Observe** view.
|
||||
|
||||
You should see the **Dashboard** tab. Set the time range to the `Last 1 hour` then scroll through the dashboard.
|
||||
|
||||
How much cpu and memory is your ParksMap application currently using?

summary: "Let's scale our application up 📈"
|
||||
---
|
||||
|
||||
We have our application deployed, let's scale it up.
|
||||
|
||||
While **Services** provide routing and load balancing for **Pods**, the higher level **Deployment** resource specifies how many replicas of our application will be created and is a simplistic way to configure scaling for the application.
|
||||
|
||||
> Note: To learn more about **Deployments** refer to this [documentation](https://docs.openshift.com/container-platform/4.14/applications/deployments/what-deployments-are.html).
|
||||
|
||||
|
||||
## 3.1 - Reviewing the parksmap deployment
|
||||
|
||||
Let's start by confirming how many `replicas` we currently specify for our ParksMap application. We'll also use this exercise step to take a look at how all resources within OpenShift can be viewed and managed as [YAML](https://www.redhat.com/en/topics/automation/what-is-yaml) formatted text files which is extremely useful for more advanced automation and GitOps concepts.
|
||||
|
||||
Start in the **Topology** view of the **Developer** perspective.
|
||||
|
||||
Click on your "Parksmap" application icon and click on the **D parksmap** deployment name at the top of the right hand panel.
|
||||
|
||||
From the **Deployment details** view we can click on the **YAML** tab and scroll down to find the following:
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
replicas: 1
|
||||
```
