# Check Disk Space
Check remaining disk space on the ProSBC Linux host. Standard Linux commands also work, since the host runs a standard distribution.
### Check disk space
From the web interface you can see the free disk space:
```
Hosts -> Status -> Select Host -> Filesystem Usage tab
```
From the [SSH access](/troubleshooting-and-support/troubleshooting-tips-and-actions/tbsigtrace-signaling-trace-capture-tool/accessing-device.md), here are the available commands.\
With the df command you can see the available disk space of each partition. If any partition shows Use% at 100%, please contact support.
```
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 3.9G 2.1G 1.7G 56% /
/dev/sda7 21G 9.0G 11G 46% /mnt/.0
/dev/sda6 2.0G 36M 1.9G 2% /tmp
/dev/sda2 4.9G 887M 3.8G 19% /var
/dev/sda1 494M 26M 443M 6% /boot
tmpfs 997M 0 997M 0% /dev/shm
```
With the du command, you can see the relative size of each folder:
```
du -sh *
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://prosbcdocs.telcobridges.com/maintenance-and-troubleshooting/maintenance-guide/check-disk-space.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
