# Modify Storage Metrics Schedule

ESS includes a [Storage Metrics](https://docs.inrupt.com/ess/services/service-pod-management/service-pod-storage#storage-metrics) feature to gather the following metrics:

* The total number of Pods
* The number of Pods that have been “Created” (where the provision has been confirmed)
* The number of Pods that have been “Deleted”(marked for deletion; i.e., soft-deleted).

Specifically, Storage Metrics runs as a [Kubernetes CronJobs](https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/).

You can use Kustomize to modify the schedule of when the job runs.

## Example Customizations

{% hint style="warning" %}
**Important**\
Gathering Storage Metrics operations may negatively impact the performance of your system. If possible, schedule the CronJob to run at times when you can minimize its impact.
{% endhint %}

The provided overlays are configured to run every 2 minutes.

If instead you wish to schedule the job to run every day at midnight ( **`0 0 * * *`** ):

1. Go to your ESS installation directory:

   ```sh
   cd ${HOME}/ess
   ```
2. Create a **`kustomize-storage-metrics.yaml`** file with the following content:

   ```javascript
   apiVersion: batch/v1
   kind: CronJob
   metadata:
     name: ess-storage-metrics
   spec:
     schedule: '0 0 * * *'
   ```
3. Modify the **`kustomization.yaml`** (i.e., step 3 of the [Applying Your Customizations](https://docs.inrupt.com/ess/2.5/installation/..#applying-your-customizations) procedure) to use **`kustomize-storage-metrics.yaml`** .\
   Specifically, add the highlighted content to the **`kustomization.yaml`** file to the `patches` section:

{% hint style="info" %}
**Tip**

If **`patches`** key does not exist in **`kustomization.yaml`** , add the **`patches`** key as well.
{% endhint %}

```yaml
# kustomization.yaml in your ESS installation directory

# ...  Preceding content omitted for brevity 
# ...

patches:
  - path: kustomize-storage-metrics.yaml
```

4\. Continue with the rest of the [Applying Your Customizations](https://docs.inrupt.com/ess/2.5/installation/..#applying-your-customizations) procedure.
