Memory
======
Glances uses two columns: one for the ``RAM`` and one for the ``SWAP``.
.. image:: ../_static/mem.png
If enough space is available, Glances displays extended information for
the ``RAM``:
.. image:: ../_static/mem-wide.png
A character is also displayed just after the MEM header and shows the
trend value:
======== ==============================================================
Trend Status
======== ==============================================================
``-`` MEM value is equal to the mean of the six latests refreshes
``\`` MEM value is lower than the mean of the six latests refreshes
``/`` MEM value is higher than the mean of the six latests refreshes
======== ==============================================================
Alerts are only set for used memory and used swap.
Legend:
======== ============
RAM/Swap Status
======== ============
``<50%`` ``OK``
``>50%`` ``CAREFUL``
``>70%`` ``WARNING``
``>90%`` ``CRITICAL``
======== ============
.. note::
Limit values can be overwritten in the configuration file under
the ``[memory]`` and/or ``[memswap]`` sections.
