For the storage of time series, a special time series database is used instead of MySQL or MONGO (but Zabbix is the MySQL used, so it encounters a bottleneck on Io). Now there are a lot of databases of time series, such as Graphite, OPENTSDB and the new influxdb. These three databases have been studied recently, and the Institute is now recorded. Graphite
