# Cassandra

You can export statistics to a `Cassandra` or `Scylla` server. The connection should be defined in the Glances configuration file as following:

    [cassandra]
    host=localhost
    port=9042
    protocol_version=3
    keyspace=glances
    replication_factor=2
    table=localhost

and run Glances with:

    $ glances --export cassandra

The data model is the following:

    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.
