Navigate to Statistics→ Cluster load. 

Generate a report

  • Period — select a period:
  • previous day;
  • current day;
  • current week;
  • current month;
  • current year;
  • previous week
  • previous month;
  • previous year;
  • week;
  • month;
  • quarter;
  • half-a-year;
  • year;
  • any period;
  • the whole period.
  • Cluster nodes — select a cluster node to display the statistics.

Statisticsis collected for the following parameters:

  • outgoing traffic, GiB;
  • incoming traffic, GiB;
  • CPU time, sec;
  • IOPS;

Note

Per-minute statistics is kept for 5 days. Per-hour statistics is kept for one month and 3 days. Per-day statistics is kept for 2 years. When the specified periods expire, the data will be deleted.

Graphs for a random period are generated based on a per-hour statistics.

How to generate a network traffic report

To generate the report, go to Management → Virtual machines → select the virtual machine → Bandwidth.

The report displays graphs for the following data:

  • cost and threshold of incoming traffic over the day, Kbps;
  • cost and threshold of outgoing traffic over the day, Kbps;
  • speed of incoming traffic detailed by day, Kbps;
  • speed of outgoing traffic detailed by day, Kbps.

Traffic threshold is average consumption of speed.  To calculate this parameter, VMmanager:

  1. Calculates the average traffic speed each five minutes.
  2. Discards 5% peak values obtained. The maximum value of the remaining will be the traffic threshold.

How statistics is collected

Raw statistics is  kept in the file /usr/local/mgr5/var/stat/raw/mainstat/@VM_NAME/YYYYMMDDHH.stat (where VM_NAME is a virtual machine name)  and is updated every 5 minutes. Once an hour the control panel resets raw statistics and deletes it from the directory.
