# How to Enable Debug Logging?

Debug logging provides detailed service-level information that helps you identify the root causes of issues when performing operations such as creating VMs, attaching volumes, etc. Follow these steps to enable debug logging for Compute and Persistent Storage services.

## Compute

Edit the `nova_override.conf` file:

Path: `/opt/pf9/etc/nova/conf.d/nova_override.conf`

If the `[DEFAULT]` section does not exist, create it and add the following:

```bash
[DEFAULT]
debug = true
```

Restart the Compute service:

```bash
systemctl restart pf9-ostackhost
```

### Persistent Storage

Edit the `cinder_override.conf`file:

Path: `/opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder_override.conf`

If the `[DEFAULT]` section does not exist, create it and add the following:

```bash
[DEFAULT]
debug = true
```

Restart the Storage service:

```bash
systemctl restart pf9-cindervolume-base
```

### Networking

Edit the `neutron.conf` file:

Path: `/opt/pf9/etc/neutron/conf.d/neutron.conf`

If the `[DEFAULT]` section does not exist, create it and add the following:

```bash
[DEFAULT]
debug = true
```

Restart the Neutron service

```bash
systemctl restart pf9-ostackhost
```

## Reverting Debug Logging

Debug logging generates large log files that may consume significant disk space. Once troubleshooting is complete, revert the changes to preserve storage.

Open the respective configuration file and remove the `debug = true` line or set it to `debug = false`.

Restart the service:

```bash
systemctl restart pf9-ostackhost
```

## 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/pcd/compute/how-to-enable-debug-logging.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.
