Overview

The Monitoring tab provides live performance charts for your virtual machine. Data is organized into five sub-tabs: General, CPU, Memory, Disk, and Network. Charts auto-refresh every 20 seconds so you can observe trends without manually reloading the page.

General

The General sub-tab gives you a high-level summary of all four metric categories in a single view. It displays four compact charts arranged in a two-by-two grid:

• CPU — CPU usage as a percentage.
• Memory — Memory usage as a percentage.
• Disk — Disk usage or disk latency, depending on the cloud environment.
• Network — Network throughput in KBps.

Each chart shows the last 15 minutes of activity and displays the most recent value alongside the chart. Click any chart to navigate directly to the corresponding detailed sub-tab.

CPU

The CPU sub-tab provides detailed processor metrics. Use the metric type selector to switch between the following measurements:

• CPU usage (%) — CPU usage as a percentage during the interval.
• CPU frequency (GHz) — CPU usage in megahertz during the interval.
• CPU ready time (ms) — Time that the virtual machine was ready but could not get scheduled to run on the physical CPU during the last measurement interval.

Memory

The Memory sub-tab shows memory consumption and swap activity. Available metrics:

• RAM usage (%) — Percentage of host physical memory that has been consumed.
• Host cache swap in rate (KBps) — Rate at which guest physical memory is swapped in from the swap space.
• Host cache swap out rate (KBps) — Rate at which guest physical memory is swapped out to the swap space.
• Ballooned memory (KB) — Amount of guest physical memory reclaimed from the virtual machine by the balloon driver in the guest.
• Consumed (KB) — Amount of host physical memory consumed for backing up guest physical memory pages.

Disk

The Disk sub-tab displays disk I/O metrics. The available metric depends on the cloud environment:

• Average number of disk reads — Average number of disk reads per second during the collection interval (public cloud).
• Disk latency (ms) — Highest latency value across all disks used by the host (private cloud).

The metric type selector is disabled on the Disk sub-tab because only one metric is available per environment.

Network

The Network sub-tab tracks network throughput and packet activity. Available metrics vary by cloud environment.

On all environments:

• Network usage (KBps) — Network utilization (combined transmit-rates and receive-rates) during the interval.

Additional metrics on public cloud:

• Data received (KBps) — Average rate at which data was received during the interval.
• Bandwidth usage (KBps) — The current network bandwidth usage for the host.

Additional metrics on private cloud:

• Dropped packages (num) — The aggregate network dropped packets for the host.

Time Periods and Export

On each detailed sub-tab (CPU, Memory, Disk, Network), you can select a time period for the chart data:

• Real-time (last 15 min) — The default view. Auto-refreshes every 20 seconds.
• Last 1 hour
• Last 6 hours
• Last 48 hours

Auto-refresh is active only in the real-time view. When you select a longer time period, the chart displays a static snapshot of that window.

Summary Table

Below the chart, a summary table shows the Current, Average, Max, and Min values for each metric in the selected category and time period.
