Introduction to atop

atop is a monitor for Linux that can report the activity of all processes and resource consumption by all processes at regular intervals. It shows system-level activity related to the CPU, memory, disks, and network layers for every process. It also logs system and process activities daily and saves the logs in disks for long-term analysis.

    (Recommended) Creating a Key Pair on the Management Console

    -

    Scenarios

    You can use the management console to create a key pair. ECS stores the public key and you store the private key.

    +

    Scenarios

    You can create a key pair on the management console. After the key pair is created, the public key is automatically stored in the system, and the private key is stored in your local computer. After a key pair is created for an ECS on the management console, ensure that you store your private key in a secure place. Without a private key, you will not be able to log in to the ECS.

    Procedure

    1. Log in to the management console.
    2. Click in the upper left corner and select your region and project.
    3. Under Computing, click Elastic Cloud Server.
    4. In the navigation pane on the left, choose Key Pair.
    5. On the displayed page, click Create Key Pair.
    6. Enter a key pair name.

      A key pair name consists of two parts: KeyPair and four random digits (KeyPair-xxxx).

    7. Click OK.
    8. Manually or automatically download a .pem private key file with the name that you specify as the key name. Store it in a secure place and click OK.

      This is the only chance for you to save the private key file. Keep it secure. You'll need to provide the key pair name when you create an ECS, and the corresponding private key each time you connect to the ECS through SSH.

      Table 1 Possible causes and solutions

      Possible Cause

      +

      Solution

      +

      The ECS is frozen or stopped.

      +

      Make sure that the ECS is in the Running state. For details, see Checking the ECS Status.

      +

      The entered username or password is incorrect.

      +

      The default username for Windows ECSs is Administrator. For details, see Checking the Login Mode.

      +

      The ECS is overloaded.

      +

      If the bandwidth or CPU usage of the ECS is excessively high, login failures may occur. For details, see Checking Whether the ECS Is Overloaded.

      +

      The ECS has no EIP bound.

      +

      To log in to an ECS using RDP or MSTSC, ensure that the ECS has an EIP bound. For details, see Checking Whether an ECS Has an EIP Bound.

      +

      The access is blocked by the Internet service provider (ISP).

      +

      Check whether you can access the ECS using another hotspot or network. For details, see Checking Whether the Network Is Normal.

      +

      The access is blocked by the firewall.

      +

      Disable the firewall and try again. For details, see Checking Whether the Firewall Is Correctly Configured.

      +

      The remote login port has been disabled in the security group or on the ECS.

      +

      Check whether the security group and the ECS allow traffic on the remote login port. For details, see Checking Whether the Remote Access Port Is Correctly Configured.

      +

      An IP address whitelist for SSH logins has been configured.

      +

      Check whether an SSH login IP address whitelist is configured after HSS is enabled. For details, see Checking the IP Address Whitelist for SSH Logins (with HSS Enabled).

      +

      The remote desktop protocol has been disabled on the ECS.

      +

      Make sure that the remote desktop protocol has been enabled on the ECS (only required for RDP and MSTSC logins). For details, see Checking the Remote Desktop Protocol on the ECS.

      +

      The access is blocked by third-party antivirus software.

      +

      Disable or uninstall the third-party antivirus software and try again. For details, see Checking Whether the Access Is Blocked by Antivirus Software.

      +

      The cause is displayed in the error message.

      +

      If an error message is displayed during remote login, check the operation guide based on the error information. For details, see Checking Whether an Error Occurred During a Remote Login.

      +
      +
      +
      +

      Checking the ECS Status

      Check whether the ECS is in the Running state on the management console. If the ECS is stopped, start it and try to log in to the ECS again.

      +
      Figure 3 Checking the ECS status
      +
      +

      Checking the Login Mode

      Check the login mode you set when you created the ECS.

      +
      Figure 4 Login Mode
      +
      • Key pair: If your ECS is authenticated using a key pair, use the key pair to obtain a password before login.
        1. Locate the ECS whose password is to be obtained, choose More > Get Password in the Operation column.
        2. Copy the content of the private key file and paste it into the text box. Click Get Password to obtain a new random password.
        +
      +
      +

      Checking Whether the ECS Is Overloaded

      If the bandwidth or CPU usage of the ECS is excessively high, login failures may occur.

      +

      If you have created an alarm rule in Cloud Eye, the system automatically sends an alarm notification to you when the bandwidth or CPU usage reaches the threshold specified in the rule.

      +

      To resolve this issue, perform the operations described in Why Is My Windows ECS Running Slowly?

      +
      • If the login failure is caused by high CPU usage, perform the following operations to reduce the CPU usage:
        • Stop certain processes that are not used temporarily and try again.
        • Verify that the Windows Update process is not running on the backend.
        • Restart the ECS.
        • Reinstall the ECS OS. Back up important data before the reinstallation.
        • If the ECS OS cannot be reinstalled due to important data, replace the disk attached to the ECS. To do so, back up data on the original disk, detach the disk from the ECS, attach the new disk to the ECS, and copy data to the new disk.
        +

        You can also upgrade the vCPUs and memory by modifying ECS specifications.

        +
      • If the login fails because the bandwidth exceeds the limit, perform the following operations:

        For instructions about how to increase the bandwidth, see Modifying an EIP Bandwidth.

        +
      +

      After you perform the preceding operations, try to remotely log in to the ECS again.

      +
      +

      Checking Whether an ECS Has an EIP Bound

      An ECS can access the Internet only after it has an EIP bound.

      +

      Before logging in to an ECS using MSTSC, make sure that an EIP has been bound to the ECS. For details, see Assigning an EIP and Binding It to an ECS.

      +

      If you log in to an ECS over an intranet, for example, using VPN or Direct Connect, you do not need to bind an EIP to the ECS.

      +
      +
      +

      Checking Whether the Network Is Normal

      Use a local PC in another network or use another hotspot to access the ECS. Check whether the fault occurs on the local network. If so, contact the carrier to resolve this issue.

      +

      After you perform the preceding operations, try to remotely log in to the ECS again.

      +
      +

      Checking Whether the Firewall Is Correctly Configured

      Check whether the firewall is enabled.

      +
      1. Log in to the Windows ECS.
      2. Click the Windows icon in the lower left corner of the desktop and choose Control Panel > System and Security > Windows Firewall.
        Figure 5 Windows Firewall
        +
      3. Click Check firewall status and select Turn on Windows Firewall or Turn off Windows Firewall.

        View and set the firewall status.

        +
        Figure 6 Turning off a firewall
        +
      +

      Ensure that the remote access port on the local end is allowed on the firewall. The default port is TCP 3389.

      +

      If the port configured in the inbound rule of the firewall is different from that configured on the remote server, the remote login will fail. If this occurs, add the port configured on the remote server in the inbound rule of the firewall.

      +

      +

      The default port is 3389. If you use another port, add that port in the inbound rule of the firewall.

      +
      +

      After you perform the preceding operations, try to remotely log in to the ECS again.

      +
      +

      Checking Whether the Remote Access Port Is Correctly Configured

      1. Check whether port 3389 (used by default) on the ECS is accessible.

        Ensure that port 3389 has been added in the inbound rule.

        +

        On the ECS details page, click the Security Groups tab and check port 3389 in the inbound rule of the security group.

        +
        Figure 7 Checking remote access ports
        +

        If you need to modify security group rules, see Modifying a Security Group Rule.

        +
      2. Check whether the remote connection port is changed.
        1. Choose Start > Run, enter cmd, and press Enter. In the CLI, enter regedit to open Registry Editor.
        2. In HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP Tcp\PortNumber, check whether the port is the default port 3389. If not, change the port to port 3389.

          +
        +
      3. Check whether the number of connections is limited.

        Check the internal remote desktop configuration of the ECS.

        +
        1. Choose Start > Run, enter cmd, and press Enter. In the CLI, enter gpedit.msc to open Local Group Policy Editor.
        2. Choose Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections. Then, in the Limit number of connections dialog box, check whether the number of connections is limited.

          +

          If Limit number of connections is set to Enabled, a remote connection to the Windows ECS may fail when the number of connections exceeds the limit. In such a case, disable Limit number of connections or set a larger limit for connections.

          +
          +
        +
      +
      +

      After you perform the preceding operations, try to remotely log in to the ECS again.

      +

      Checking the IP Address Whitelist for SSH Logins (with HSS Enabled)

      After HSS is enabled, you can configure an IP address whitelist for SSH logins as required. The IP address whitelist controls SSH access to ECSs, effectively preventing account cracking.

      +

      After you configure the allowlist, SSH logins will be allowed only from IP addresses in the allowlist.

      +
      1. On the Events page, check whether a local host IP address is intercepted due to brute force cracking.
      2. Check whether the IP address whitelist for SSH logins has been enabled. If it has been enabled, ensure that the IP address of the local host has been added to the IP address whitelist.
        • Before enabling this function, ensure that all IP addresses that need to initiate SSH logins are added to the allowlist. Otherwise, you cannot remotely log in to your ECS through SSH.
        • Exercise caution when adding a local IP address to the allowlist. This will make HSS no longer restrict access from this IP address to your ECSs.
        +
        +

        For more details, see Configuring Server Login Protection.

        +
      +
      +

      Checking the Remote Desktop Protocol on the ECS

      Make sure that the remote desktop protocol has been enabled on the ECS (only required for MSTSC logins).

      +

      Log in to the ECS using VNC and enable the remote desktop protocol.

      +
      +

      Checking Whether the Access Is Blocked by Antivirus Software

      Third-party antivirus software may lead to a failure in accessing the ECS.

      +

      If third-party antivirus software is running, check whether the remote connection is blocked by the software. If the remote connection is blocked, add the EIP bound to the ECS to the whitelist of the antivirus software and try to access the ECS again.

      +

      You can also disable or uninstall the third-party antivirus software and try to remotely log in to the ECS again.

      +
      +

      Checking Whether an Error Occurred During a Remote Login

      If an error message is displayed during remote login, check the operation guide based on the error information.

      +

      If the fault persists, record the resource details and fault occurred time, and contact technical support for assistance

      +
      +

      If the fault persists after the preceding operations are performed, record the resource details and fault occurred time, and contact customer service for technical support.

            Network QoS

            Network QoS uses basic technologies to improve the quality of network communication. A network with QoS enabled offers predictable network performance and effectively allocates network bandwidth to use network resources.

            To obtain the QoS data of an ECS flavor, including the maximum bandwidth, assured bandwidth, maximum intranet PPS, and NIC multi-queue, see A Summary List of ECS Specifications.

            -
            Constraints on network performance vary depending on ECS flavors.
            • Assured intranet bandwidth: indicates the guaranteed bandwidth allocated to an ECS when there is a network bandwidth contention in the entire network.

          • Certain G-series ECSs do not support remote login from the console. If you need to remotely log in to the ECSs, install the VNC server on them. For details, see GPU-accelerated ECSs. You are advised to log in to such ECSs using MSTSC.
          • If you log in to a GPU-accelerated ECS using MSTSC, GPU acceleration will fail. This is because MSTSC replaces the WDDM GPU driver with a non-accelerated remote desktop display driver. In such a case, you must log in to the ECS using other methods, such as VNC. If the remote login function available on the management console fails to meet your service requirements, you must install a suitable remote login tool, such as TightVNC, on the ECS.

            • Common deep learning frameworks, such as TensorFlow, Caffe, PyTorch, and MXNet
            • CUDA GPU rendering supported by RedShift for Autodesk 3ds Max and V-Ray for 3ds Max
            • Agisoft PhotoScan
            • MapD

            Notes
            • After a P2s ECS is stopped, basic resources (including vCPUs, memory, image, and GPUs) are not billed, but its system disk is billed based on the disk capacity. If other products, such as EVS disks, EIP, and bandwidth are associated with the ECS, these products are billed separately.

              Resources will be released after a P2s ECS is stopped. If resources are insufficient at the next start, the start may fail. If you want to use such an ECS for a long period of time, do not stop the ECS.

                If the partition style is changed after the disk has been used, all data on the disk will be lost, so take care to select an appropriate partition style when initializing the disk.

                    On the ECS details page, click Network Interfaces and disable Source/Destination Check.

                    By default, the source/destination check function is enabled. When this function is enabled, the system checks whether source IP addresses contained in the packets sent by ECSs are correct. If the IP addresses are incorrect, the system does not allow the ECSs to send the packets. This mechanism prevents packet spoofing, thereby improving system security. However, this mechanism prevents the packet sender from receiving returned packets. You need to disable the source/destination check.

                    Why Does a Forcibly-Stopped Linux ECS Fail to Be Restarted?

                    +

                    Symptom

                    When you try to restart a forcibly-stopped Linux ECS, the ECS failed to be restarted, as shown in Figure 1.

                    +
                    Figure 1 Restart failure
                    +
                    +

                    Possible Causes

                    As shown in Figure 1, the ECS cannot be restarted because the file system was damaged. Forcibly stopping or restarting an ECS is highly risky because this operation may cause inconsistent metadata in the file system, leading to the file system damage.

                    +
                    +

                    Solution

                    Use the disk repair tool (fsck) delivered with the Linux OS to rectify the fault.

                    +

                    The following procedure considers the affected disk partition as /dev/xvdb1, which is the partition shown in Figure 1.

                    +
                    1. Enter the password of user root as prompted.
                    2. Run the following command to check whether the affected disk partition has been mounted:

                      mount | grep xvdb1

                      +
                      • If yes, go to step 3.
                      • If no, go to step 4.
                      +
                    3. Run the following command to unmount the affected disk partition:

                      umount /dev/xvdb1

                      +
                    4. Run the following command to rectify the file system of the affected disk partition:

                      fsck -y /dev/xvdb1

                      +
                    5. Run the following command to restart the ECS:

                      reboot

                      +

                      If the fault persists, contact customer service for technical support.

                    Why Can't I Log In to My Linux ECS?

                    +

                    Symptom

                    A Linux ECS cannot be logged in to due to some reasons. For example, the network is abnormal, the firewall does not allow access to the local port for accessing the remote desktop, or the ECS vCPUs are overloaded.

                    +

                    This section describes how to troubleshoot login failures on a Linux ECS.

                    +

                    If you cannot log in to your Linux ECS, follow the instructions provided in Checking the VNC Login. Then, locate the login fault by referring to Fault Locating.

                    +
                    +

                    Checking the VNC Login

                    Check whether you can log in to the ECS using VNC on the management console.

                    +
                    1. Log in to the management console.
                    2. Under Computing, choose Elastic Cloud Server.
                    3. In the Operation column of the target ECS, click Remote Login.

                      +
                      Figure 1 Remote login
                      +
                    4. (Optional) When the system displays "Press CTRL+ALT+DELETE to log on", click Send CtrlAltDel in the upper part of the remote login page to log in to the ECS.

                      Do not press CTRL+ALT+DELETE on the physical keyboard because this operation does not take effect.

                      +
                      +
                    +

                    If the VNC login still fails, record the resource details and fault occurred time for further fault locating and analysis.

                    +
                    +

                    Fault Locating

                    If you can log in to the ECS using VNC but cannot log in to the ECS using a remote desktop connection, locate the fault as follows.

                    +

                    The following fault causes are sequenced based on their occurrence probability.

                    +

                    If the fault persists after you have ruled out a cause, check other causes.

                +

                Solution

                +

                The ECS is frozen or stopped.

                +

                Make sure that the ECS is in the Running state. For details, see Checking the ECS Status.

                +

                The entered username or password is incorrect.

                +

                The default username for Linux ECSs is root. For details, see Checking the Login Mode.

                +

                The ECS is overloaded.

                +

                If the bandwidth or CPU usage of the ECS is excessively high, login failures may occur. For details, see Checking Whether the ECS Is Overloaded.

                +

                The ECS has no EIP bound.

                +

                To log in to an ECS using RDP or MSTSC, ensure that the ECS has an EIP bound. For details, see Checking Whether an ECS Has an EIP Bound.

                +

                The access is blocked by the ISP.

                +

                Check whether you can access the ECS using another hotspot or network. For details, see Checking Whether the Network Is Normal.

                +

                The security group of the ECS denies inbound traffic on the remote login port.

                +

                Check whether the security group allows inbound traffic on the remote login port. For details, see Checking Whether the Security Group Is Correctly Configured.

                +

                The remote access port is incorrectly configured.

                +

                Check whether the remote access port is correctly configured on the local computer and the ECS. For details, see Checking Whether the Remote Access Port Is Correctly Configured.

                +

                An IP address whitelist for SSH logins has been configured.

                +

                Check whether an SSH login IP address whitelist is configured after HSS is enabled. For details, see Checking the IP Address Whitelist for SSH Logins (with HSS Enabled).

                +

                An OS fault has occurred.

                +

                The file system is damaged. For details, see Checking Whether an OS Fault Has Occurred.

                +

                The access is blocked by third-party antivirus software.

                +

                Disable or uninstall the third-party antivirus software and try again. For details, see Checking Whether the Access Is Blocked by Antivirus Software.

                +

                The cause is displayed in the error message.

                +

                If an error message is displayed during remote login, check the operation guide based on the error information. For details, see Checking Whether an Error Occurred During a Remote Login.

                Checking Whether the ECS Is Overloaded

                If the bandwidth or CPU usage of the ECS is excessively high, login failures may occur.

                +

                If you have created an alarm rule in Cloud Eye, the system automatically sends an alarm notification to you when the bandwidth or CPU usage reaches the threshold specified in the rule.

                +

                To resolve this issue, perform the operations described in Why Is My Linux ECS Running Slowly?

                +
                • If the login failure is caused by high CPU usage, perform the following operations to reduce the CPU usage:
                  • Stop certain processes that are not used temporarily and try again.
                  • Restart the ECS.
                  • Reinstall the ECS OS. Back up important data before the reinstallation.
                  • If the ECS OS cannot be reinstalled due to important data, replace the disk attached to the ECS. To do so, back up data on the original disk, detach the disk from the ECS, attach the new disk to the ECS, and copy data to the new disk.
                  +

                  You can also upgrade the vCPUs and memory by modifying ECS specifications.

                  +
                • If the login fails because the bandwidth exceeds the limit, perform the following operations:

                +
                +

                Checking Whether an ECS Has an EIP Bound

                If you need to use a remote login tool (such as PuTTY or Xshell) to access the ECS, bind an EIP to the ECS.

                +

                +

                Checking Whether the Security Group Is Correctly Configured

                Check whether the local host can access port 22 on the ECS.

                +

                Run the following command to check whether port 22 is accessible:

                +

                telnet ECS private IP address

                +

                If port 22 is inaccessible, check whether port 22 is opened in the security group rule.

                +

                On the ECS details page, click the Security Groups tab and check that port 22 is configured in the inbound rule of the security group.

                Check ECS settings.
                1. Check whether the sshd process is running.
                2. Check whether your local PC is denied by the ECS.
                  1. Log in to the ECS and run the following command:

                    vi /etc/hosts.deny

                    +
                  2. If the IP address of the local PC is in the hosts.deny file, the ECS denies connection attempts from the local PC. In such a case, delete the IP address from the file.
                  +
                3. Open the /etc/ssh/ssh_config file in the local PC and view the default login port. Then, open the /etc/ssh/sshd_config file in the ECS and check whether the SSH port is the default port 22.

                Checking the IP Address Whitelist for SSH Logins (with HSS Enabled)

                After HSS is enabled, you can configure an IP address whitelist for SSH logins as required. The IP address whitelist controls SSH access to ECSs, effectively preventing account cracking.

                +

                After you configure the allowlist, SSH logins will be allowed only from IP addresses in the allowlist.

                +
                1. On the Events page, check whether a local host IP address is intercepted due to brute force cracking.
                2. Check whether the IP address whitelist for SSH logins has been enabled. If it has been enabled, ensure that the IP address of the local host has been added to the IP address whitelist.
                  • Before enabling this function, ensure that all IP addresses that need to initiate SSH logins are added to the allowlist. Otherwise, you cannot remotely log in to your ECS through SSH.
                  • Exercise caution when adding a local IP address to the allowlist. This will make HSS no longer restrict access from this IP address to your ECSs.
