# Use resilience probe
This topic describes the steps you can follow to create and use a resilience probe in your chaos experiment.
### Before you begin, review the following
* Go to [probe overview](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/index.md) to understand about probes.
* Go to [chaos faults](/resilience-testing/chaos-engineering/faults/index.md) to understand the application of resilience probes.
#### Prerequisite
* Permissions to edit a chaos experiment.
{% hint style="info" %}
* If you are an existing customer, you will see the old flow of control in resilience probes by default and you have the choice to upgrade to the new flow.
* If you are a new customer, the feature flag is turned on by default and you will see the new flow of control in the resilience probes.
{% endhint %}
### Create a Resilience Probe from UI
{% tabs %}
{% tab title="Interactive Guide" %}
{% embed url="" %}
{% endtab %}
{% tab title="Step-by-Step" %}
1. Select the **Chaos** module and navigate to **Resilience probes**. Click **New probe**.
2. Select the desired infrastructure (Kubernetes or Linux) and the probe type.
3. Based on the probe type you choose, the fields will vary. You can find details about every probe in their respective documentation (([Command](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/command-probes/index.md), [Datadog](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/datadog-probe.md), [Dynatrace](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/dynatrace-probe.md), [HTTP](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/http-probe.md), [Kubernetes](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/kubernetes-probe.md), [Prometheus](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/apm-probes/prometheus-probe.md), and [SLO](/resilience-testing/chaos-engineering/use-chaos-engineering/probes/slo-probe.md))). After entering the details, click **Configure properties**. Enter further details and click **Configure details**.
4. Enter URL, authorization type, and click **Setup Probe**. Click **Confirm** when the screen prompts you to confirm creating the probe with specified details.
{% hint style="info" %}
**NOTE**
If you are a first-time chaos module user or a [Platform](/harness-ai/readme.md) user who has not used resilience probes, you can create a resilience probe directly from the Chaos Studio drawer (from within an experiment). For this, you will see an option to add a system probe (which is a health check system probe) as a one-click button. This will not be present if you have configured at least one resilience probe.
{% endhint %}
{% endtab %}
{% endtabs %}
### Edit a Resilience Probe
You can edit a resilience probe by navigating to the probe you wish to edit. Click the three vertical dot menu to the extreme right of the probe, and choose **Edit probe**. Modify the properties you wish to, and click **Save**.
{% hint style="info" %}
Resilience probe names act as unique identifiers for a probe, which means you can't edit them. If you manually add the name of a probe in the manifest, this same name should be entered in the annotation as ID.
{% endhint %}
When you want to enter the probe name in the manifest (manually) as a probeRef annotation, follow the below format:
```
probeRef: '[{"probeID":"ID","mode":"SOT"}]'
```
Here, `ID` is the unique ID of your probe.
This step is not required if you use the user interface.
### Enable a Probe
1. Go to **Chaos** module, select **Resilience Probes** and select the **:** icon of the probe to enable. Select **Enable**.
2. Click **Confirm**.
3. Choose between **Bulk Enable** and **Enable Only**. If you choose **Bulk Enable**, this option modifies the entire manifest and references to the probe. If you choose **Enable Only**, it enables the probe functionality without affecting the manifest.
{% hint style="info" %}
* By default, **Enable Only** is applied in case you close the modal when selecting between the options **Bulk Enable** and **Enable Only**.
* You need to enable a probe if it is in the disabled state.
* A probe is enabled by default.
{% endhint %}
### Use a Resilience Probe
1. Go to the chaos experiment for wish you wish to set up probe/s. Move to **probes** tab and click **+Select or Add new probes**.
2. You can choose to [create a new probe](#create-a-resilience-probe-from-ui) or add a probe that you created earlier.
3. Once you select a probe, click **Add to Fault** to associate the resilience probe with a chaos fault.
4. Click **Apply changes** or continue to add or create probes based on your requirement.
{% hint style="info" %}
* Based on the type of probe you select, enter the values to set up the probe.
**You can:**
* Use any number of probes within a chaos experiment.
* Use the same probes for two faults within the same chaos experiment.
* Use Kubernetes-based probes for Kubernetes experiments.
* Use Linux-based probes for Linux experiments.
**You can't:**
* Repeat the same probe multiple times in the same fault in the same experiment.
{% endhint %}
### Add Probes to ChaosHub
Adding probes to ChaosHub helps you to templatize the resilience probe. With this, you can import the probes directly from ChaosHub and reference it in a chaos experiment.
1. To add a resilience probe to ChaosHub, go to **Resilience Probes** tab. Go to the resilience probe that you want to add to ChaosHub and click the **:** button. Click **Push to ChaosHub**.
2. Choose the ChaosHub to which you want to add the probe, and click **Apply**. Click **Save**.
### Disable a Probe
You can follow the steps similar to that as [Enable a Probe](#enable-a-probe), except that you select the **Disable** option. You can delete a probe only after you disable it.
