  • Performance History: pick Last 24 Hours (per hour), Last 30 Days (per day) or Last 12 Months (per month), and CPU Usage, Memory Usage, Disk Usage or Load Average.
  • Each bar is the average of its hour, day or month. Hover a bar to see the peak.
  • Network History shows the traffic in and out over the same periods.
The agent on your server takes a sample every 5 minutes. Once an hour, Opensolr stores that hour's average and its peak, so a short spike is never lost between two samples.
