As of v0.40.0 of Troubleshoot, you can now use [host collectors and analyzers](https://troubleshoot.sh/docs/host-collect-analyze/overview/) in support bundles. These are useful when you need to debug a Kubernetes cluster that is offline, troubleshoot a [kURL](https://kurl.sh/docs/install-with-kurl/) install that failed before the control plane was initialized, or if you need to collect and analyze information that isn’t available in [in-cluster collectors](https://troubleshoot.sh/docs/collect/all/).

Follow these steps to use host collectors and analyzers to troubleshoot a Kubernetes cluster that is down:

1. If you do not have `kubectl support-bundle` plugin, install the support bundle binary on a host in the cluster you need to debug

```auto
    curl -L https://github.com/replicatedhq/troubleshoot/releases/latest/download/support-bundle_linux_amd64.tar.gz | tar xzvf -

```

**NOTE** : Presently, there is no method in Troubleshoot to run host collectors on remote nodes. If you have a multi-node Kubernetes cluster, you must run the support bundle binary on each node and generate a bundle for each.

1. Generate the support bundle

**Using the downloaded binary**

```auto
    sudo ./support-bundle --interactive=false https://raw.githubusercontent.com/replicatedhq/troubleshoot-specs/main/host/default.yaml

```

**Using kubectl plugin**

```auto
    sudo -E kubectl support-bundle --interactive=false https://raw.githubusercontent.com/replicatedhq/troubleshoot-specs/main/host/default.yaml

```

**NOTE** : You may need to run the above command with ` sudo` if your current user doesn’t have the access to gather information for a specific collector

**NOTE** : For **airgapped** installations you can download the binary and the [spec](https://raw.githubusercontent.com/replicatedhq/troubleshoot-specs/main/host/default.yaml), transfer them to the target host and run `./support-bundle default.yaml`
