.. _fs:
File System
===========
.. image:: ../_static/fs.png
Glances displays the used and total file system disk space. The unit is
adapted dynamically.
Alerts are set for `user disk space usage <https://psutil.readthedocs.io/en/latest/index.html?highlight=disk%20usage#psutil.disk_usage>`_.
Legend:
===================== ============
User disk space usage Status
===================== ============
``<50%`` ``OK``
``>50%`` ``CAREFUL``
``>70%`` ``WARNING``
``>90%`` ``CRITICAL``
===================== ============
.. note::
Limit values can be overwritten in the configuration file under
the ``[fs]`` section.
By default, the plugin only displays physical devices (hard disks, USB
keys). To allow other file system types, you have to enable them in the
configuration file. For example, if you want to allow the ``shm`` file
system:
.. code-block:: ini
[fs]
allow=shm
Also, you can hide mount points using regular expressions.
To hide all mount points starting with /boot and /snap:
.. code-block:: ini
[fs]
hide=/boot.*,/snap.*
Filtering are also applied on device name (Glances 3.1.4 or higher).
Example to hide all /dev/sdb mount points:
.. code-block:: ini
[fs]
hide=/dev/sdb.*
