# List All Instances, Username, And Tenants in OpenStack Region

## Problem

Obtain a complete list of instance names, tenant name, region name mapped to the corresponding username in an OpenStack region.

## Environment

* Platform9 Managed OpenStack - All Versions

## Procedure

1. Source the RC file for admin user of your environment.

{% tabs %}
{% tab title="None" %}

```none
$ source [your_rc_file].rc
```

{% endtab %}
{% endtabs %}

2. Run the script on **each region.**

{% tabs %}
{% tab title="None" %}

```none
# Give +x permission to the script before executing.# Run this bash script on each region.echo -e "Instance_Name \t Region \t Username \t \t \t Tenant"for name in $(openstack server list --all -c ID -c Status -f value | awk '{if ($2 != "ERROR") print $1}' )dovm_name=$(openstack server show $name -c name -f value 2> /dev/null)if [[ $vm_name ]];thenUser_name=$(openstack user list | grep `openstack server show $name -c user_id -f value` | awk '{$1=$2=$3="";print $4}' | sed 's/|//g')tenant_name=$(openstack project show -f value -c name $(openstack server show $name -f value -c project_id))echo -e "${vm_name} \t ${OS_REGION_NAME} \t ${User_name} \t ${tenant_name}"fidone
```

{% endtab %}
{% endtabs %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/pmo/how-to/list-all-instances-username-and-tenants-in-openstack-region.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
