VMmanager collects statistics on resource usage on cluster nodes and virtual machines (VMs). These statistics are used to display graphs on the pages of VMs and nodes, on the dashboard and in Grafana.

Data is grouped by months and stored on the server with the platform in the /opt/ispsystem/vm/clickhouse directory. The storage period and parameters of statistics collection are set in the platform settings. At the beginning of each month, the platform deletes statistics data that has exceeded the storage period.

To manage statistics data, enter → Statistics settings.
