Viewing information about a cluster node

To view information about a cluster node:

  1. In the application web interface window, select Nodes.
  2. Select the node whose information you want to view.

    A window containing information about the node opens.

The window contains the following information depending on server type:

  1. Node information settings group:
    • Certificate fingerprint is the certificate fingerprint of the server.
    • Virtualization technology is the name of the virtualization platform (displayed only if the application ISO image is deployed on a virtual machine).

      The following values are possible:

      • ACRN.
      • bhyve (FreeBSD™ hypervisor)
      • Bochs Emulator
      • Linux KVM
      • Microsoft Hyper-V
      • Not used means that the application is installed on a physical server.
      • Oracle® VM VirtualBox
      • Parallels Desktop® or Server
      • QEMU.
      • QNX
      • UML (user-mode Linux)
      • VMware™ Workstation or Server
      • Xen
      • z/VM

      Kaspersky Web Traffic Security supports Microsoft Hyper-V and VMware ESXi hypervisors, and supports deployment of the application ISO image on a physical server. Application performance cannot be guaranteed when using other hypervisors.

    • Comment is additional information about the node. Optional setting.
    • Current node role is the role of the current node in the cluster.
  2. Traffic processing settings group:
    • Scan threads is the number of simultaneous traffic processing threads of the ICAP server.
    • License expiration date.
    • License is information about the license and the number of days left until the license expires.
    • License type is the type of license (trial or commercial).
    • Serial number is the serial number of the license.
    • KSN/KPSN status is the status of the connection with KSN/KPSN services.
    • Anti-Virus is the state of the Anti-Virus module databases.
    • Anti-Phishing is the state of the Anti-Phishing module databases.
    • Uploading files to KATA – presence or absence of errors when sending files to KATA (displayed only when Uploading files mode is enabled).
    • Receiving objects from KATA – presence or absence of errors when receiving objects detected by KATA (displayed only when Receiving objects mode is enabled).
    • Database update is the state of the application databases and the result and time of their last successful update.
  3. LDAP cache status settings group (displayed only if integration with an Active Directory domain is configured):
    • Connection is the date and time of the last successful connection to the Active Directory domain controller.
    • Data for rules matching is the date and time of the last successful update of user account data used for selecting traffic processing rules.
    • User accounts autofill is the date and time of the last successful update of data used for autocompletion of user names in the application web interface.

    If at least one of these steps results in an error, the cluster nodes table shows an error message.

  4. Settings group:
    • For the node with role Control:
      • Applied refers to the last time when settings were successfully applied to application modules.
      • Time is the status of time synchronization between the hypervisor and the NTP server (displayed only if the application ISO image is deployed on a virtual machine).
    • For a node with role Secondary:
      • Synchronized refers to the last time when settings were successfully received from the node with role Control. If settings were received, you can assign the Control role to this node with role Secondary without losing the defined settings.
      • Applied refers to the last time when settings were successfully applied to application modules.
      • Timeis the status of time synchronization with the following:
        • Server hosting the node with role Control
        • Hypervisor (displayed only if the application ISO image is deployed on a virtual machine)
        • NTP server (displayed only if the application ISO image is deployed on a virtual machine)

    If the status is Failure, you can copy error information to the clipboard by clicking the Copy link on the right of the status.
