.. _cassandra:
Cassandra
=========
You can export statistics to a ``Cassandra`` or ``Scylla`` server.
The connection should be defined in the Glances configuration file as
following:
.. code-block:: ini
[cassandra]
host=localhost
port=9042
protocol_version=3
keyspace=glances
replication_factor=2
table=localhost
and run Glances with:
.. code-block:: console
$ glances --export-cassandra
The data model is the following:
.. code-block:: ini
CREATE TABLE <table> (plugin text, time timeuuid, stat map<text,float>, PRIMARY KEY (plugin, time))
Only numerical stats are stored in the Cassandra table. All the stats
are converted to float. If a stat cannot be converted to float, it is
not stored in the database.
