View cloud server resource metrics

Last update:

You can view cloud server resource metrics as graphs in the dashboard.

If the cloud server is down, metrics are not collected.

Values for all metrics are collected every minute. If you have just created a server, the first metric values for network interfaces and disks will appear in a few minutes.

View resource utilization metrics

  1. In the dashboard, on the top menu, click Products and select Cloud Servers.

  2. Open the server page → Metrics tab.

  3. Optional: filter the metrics:

    3.1 Select a ready-made range or specify the period for which you need metrics.

    3.2. Select UTC Time or Local Time for the displayed metrics time.

  4. Check out the graphs of available cloud server metrics.

  5. If no metrics are collected on the cloud server, add autoloading of VirtiO core modules.

Cloud server metrics in the control panel

CPU
  • how many percent of the cloud server's vCPUs are utilized;
  • how many percent each vCPU of the cloud server is utilized
Memory
  • occupied RAM excluding cache and operating system buffers in bytes;
  • how many percent of RAM is occupied, excluding operating system cache and buffers
Disk
  • number of read and write operations in IOPS;
  • the number of bytes per second read from or written to the disk
Network
  • incoming and outgoing traffic in bits per second;
  • speed of incoming and outgoing traffic in packets per second

Add autoloading of VirtIO kernel modules

VirtIO drivers must be installed on the cloud server to collect metrics. In modern Linux distributions, VirtIO drivers are installed by default.

If some cloud server load metrics are not being collected, add autoloading of VirtIO kernel modules.

  1. Connect to the server.

  2. Open the /etc/modules file in the nano text editor:

    nano /etc/module

  3. Add Modules:

    virtio_blk
    virtio_scsi
    virtio_balloon
    virtio_net

  4. Perform a programmatic reboot of the server. The modules will start automatically.

  1. Connect to the server.

  2. Open the /etc/rc.modules file in the nano text editor:

    nano /etc/rc.modules

  3. Add Modules:

    modprobe virtio
    modprobe virtio_net
    modprobe virtio_balloon
    modprobe virtio_scsi
    modprobe virtio_blk

  4. Perform a programmatic reboot of the server. The modules will start automatically.
