3.2.1.2. Host

A Site is composed of one or more Hosts. Hosts can be the following items:

  • PNS firewalls,

  • CF hosts,

  • AS hosts, and

  • MS-managed hosts.

At the very minimum setup, when PNS and MS are installed on the same machine, there is one Host registered for the given Site. The number of PNS firewall nodes per Site is only limited by the number of licenses purchased. With the exception of Zone, PKI and Class Editor settings, the configuration parameters are always per Host.

To display system statistics for a Host component (MS or PNS), click on the name of the Host. The statistics are displayed under the Host tab. The following statistics are available:

  • processor

  • load average

  • uptime

  • memory usage: RAM and SWAP

  • only on PNS hosts:

    • the version number of PNS

    • the number and status of running PNS Instances, Processes and Threads

  • the validity and size of the product licenses (PNS, MS, and so on) available on the host.

    MC displays a warning if a license expires soon, and an alert e-mail can be configured as well. For details on configuring e-mail alerts for license expiry, see Procedure 11.3.8.9, Monitoring licenses and certificates.

    Note

    To access license information from the command line, login to the host and enter:

    /usr/lib/vms-transfer-agent/MS_program_status hoststat

The statistics are automatically refreshed every 30 seconds by default.

Tip

Although host statistics can seem a less important, auxiliary service, it is extremely useful when firewalls operate under continuous heavy load and you want to optimize resource allocation.
