File System

===========

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>`_.

.. 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
|
|
|
|
With the above configuration key, it is also possible to monitor NFS
|
|
mount points (allow=nfs). Be aware that this can slow down the
|
|
performance of the plugin if the NFS server is not reachable. In this
|
|
case, the plugin will wait for a 2 seconds timeout.
|
|
|
|
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).
|
|
|
|
It is also possible to configure a white list of devices to display.
|
|
Example to only show /dev/sdb mount points:
|
|
|
|
.. code-block:: ini
|
|
|
|
[fs]
|
|
show=/dev/sdb.*
|
|
|
|
Filtering is based on regular expression. Please be sure that your regular
|
|
expression works as expected. You can use an online tool like `regex101`_ in
|
|
order to test your regular expression.
