Viewing information, statistics, and graphs

Describes the detailed information, statistics, and graphs

Viewing System Information

All hardware information, system properties, system statuses, open ports and firewall rules are listed in the Information tab.

The information is organized into sections called Hardware, System Properties, System Status, Open Ports, and Firewall.

Hardware section includes information on system, chipset, processors, and amount of total RAM.

System Properties section appears with information on current Appliance, logging server, and directory server.

System Status section lists such properties as data and time, boot time, up time, number of logged in users, and average load.

Information tab: Hardware, System Properties, System Status

Open Ports section lists types, addresses, and names of services that are running.

Information tab: Open Ports

Firewall section in System > Information lists all firewall rules, firewall status (enabled/disabled), and the default policy (drop/accept) which determines what to do on packets that do not match any existing rule.

Information tab: Firewall Rules section

Viewing System Statistics

Using System > System Statistics, you can view performance statistics to assess system usage and efficiency. The Performance page refreshes itself every few seconds and shows the statistics in real time.

The Performance page shows system information:

  • Hardware - System, chipset, processors, total RAM
  • System Status - Date/time, boot time, up-time, users connected, load average
  • Networking - Interface, address, bytes sent/received, packets sent/received
  • Partitions - Partition name and size, used and avail
  • Kernel - Idle time, kernel time, I/O time, user time
  • Memory - Memory total, swap cached, and inactive, among others

You can customize the page refresh rate, so that you are viewing the latest information at any time.

Viewing Performance Graphs

Using System > Graphs, you can view performance graphs and real-time graphs in addition to statistics. In the Performance tab you can view a graphical representation of performance statistics from the past 5 minutes or past 24 hours for these items:

  • CPU application use - % CPU I/O wait, CPU system use
  • Total RAM - Free RAM, used RAM
  • Total Swap - Free Swap, used Swap
  • Free RAM
  • Used RAM
  • System CPU usage
  • Application CPU use, %
  • Log space used - Log space available, log space total
  • Application data used - Application data available space, application data total size
  • Total page faults
  • File descriptor usage
  • ethMNG incoming/ethMNG outgoing
  • ethSRV0 incoming/ethSRV0 outgoing
  • ethSRV1 incoming/ethSRV1 outgoing

In the Realtime Graphs tab you can monitor current state of performance statistics for these items:

  • CPU usage
  • Memory Status - free and used RAM

The following figure illustrates the Realtime Graphs tab.
