The operating state of the servers and services is indicated by the following icons:

SymbolMeaning
server_is_up_00.pngServer/service is up and running
server_blocked_00.pngServer/Service is blocked
server_stopped_00.pngServer/Service is stopped
server_disabled_00.pngServer/Service is blocked, stopped, or disabled because its server has been blocked, stopped, or disabled

Controlling Servers and Services

Servers and services are processes that run on the system level and are monitored by the system. In order to provide high reliability, special background processes follow the operation of servers and services and automatically restart them in case they are accidentally terminated. In addition, servers and services can also be controlled manually, e.g., for maintenance purposes.

To control a server or a service manually, you have the following options:

  • Block Server/Service – Stop the virtual server or service and prevent it from being automatically restarted.
  • Start Server/Service – Start the virtual server or service.
  • Stop Server/Service – Stop the virtual server or service. The control daemon automatically restarts the virtual server or service after a short period of time.
  • Restart Server/Service – Restart  the virtual server or service.

Server Status

The Server Status table displays the status of all available servers.

The following columns provide information on the virtual servers that have been introduced on your firewall:

  • ServerLists all servers and their status, HA partner (optional), and IP in a hierarchical tree.  Each defined server ip is listed below the ip node. Icons indicate the current status of each server.
  • Status / Status HA Partner The Status column displays the status of the server. If the system is part of an HA cluster, the Status HA Partner column displays the status of its HA partner. The columns can display any of the following statuses:
    • primary – Server is up and running, either as a single system or as the primary unit in an HA setup.
    • secondary – Server is up and running on the backup unit of an HA setup.
    • standby – Server is in standby and is waiting to take over if the HA partner goes down.
    • down – Server is not running, but is able to start automatically when triggered.
    • block – Server is blocked and unable to start automatically, even if the HA partner goes down.

      A blocked server must always be started manually.
    • disabled – Server is disabled due to virtual server monitoring configurations.

  • IP Addresses – Lists the IP addresses that the server listens on.

Service Status

The Service Status table displays the status of available services.

  • Server / Service – Lists servers and their services in a hierarchical structure. Icons indicate the current status of each service.
  • Num Proc – Displays the number of processes for each service.
  • Num FD – Displays the number of file descriptors used by the service processes.
  • Mem KB – Displays the total memory (exclusive and shared) used by the service processes.
  • Module – Displays the service name and icon.
