This section covers the following topics:

Master Server Details

The Server Information page displays the following information about the Master Server:

Section Displays
Master Host/ Master Version/ Master Public Key
  • Master Host: Master Server host name
  • Master Version: Master Server software version.
  • Master Public Key: Used to configure Node Agents. See Install Node Agents.
Server Time Displays Master Server system clock

Scan schedules by default depend on your Master Server's system clock. If your Master Server's system clock does not match a Node Agent's system clock, your scans will not run as scheduled.

To change the time shown here, access the Master Server and change its system clock.

Backup Displays the active backup policy and the status of recent backups.
See Automated Backups.
System Load Displays the Master Server system load. See System Load Graph.
System Services Displays the status of system services on the Master Server.

Interrupted Backups

Do not restart the Master Server when a backup job is in progress. You cannot resume an interrupted backup job.

Automatic Backups Stop at 50% Free Disk Space

If there is less than 50% free disk space available on the Master Server, the automatic backup policy will pause itself. Automatic backups will resume when the Master Server detects that there is more than 50% free disk space available.

Backup Status

A list of backup jobs are displayed under the backup policy details. The jobs have the following statuses:

Delete Backups

To delete backups:

  1. Hover over the backup entry. Delete appears to the right of the backup entry.

  2. Click Delete.
  3. Click Confirm to permanently delete the backup.

Restore Backups

For details on restoring backups from the Master Server console, see Restoring Backups.

System Load Graph

On the MONITORING AND ALERTS > Server Information page, you can view a graph of the Maser Server system load against time.

The graph's legend indicates the system load type shown and the corresponding colour on the graph.

To view and download a log of the system load statistics in a CSV file format, click Download Statistics.

Clicking Download Statistics downloads a CSV record of system load statistics with UTC time stamps.

To view details on a statistic, pause on a point on the line graph to view the statistic utilization percentage and the exact time stamp.

For example, the above image displays the memory usage for Wed, Jun 21 at 14:23.

Reading the Graph

The following table describes the statistics shown for both the graph and CSV file:

Graph value CSV column Description
(x axis) Time stamp The system load's statistics are recorded every 10 seconds. Statistics older than an hour are then averaged down to hourly records.
In the CSV file, the records are sorted from oldest to newest.
CPU CPU Usage % CPU usage refers to your computer's processor and how much work it's doing.
A high reading means your computer is running at the maximum level or above normal level for the number of applications running.
Memory Memory Usage % Percentage of memory used to run the processes on the Master Server.
Disk Disk Usage % Percentage of disk space that is currently in use on the Master Server.
I/O Disk I/O % Any operation, program, or device that transfers data to or from a computer.
Typical I/O devices are printers, harddisks, keyboards and mouses.

Customize the Graph

You can toggle the visibility of each statistic charted on the graph. By default, all the line graphs are shown.

To hide a statistic, click the statistic's line graph or the statistic type in the legend. When hidden, the statistic type in the legend is dimmed.

To view statistics for a set date or time period:

  1. Go to the System Load Graph. Move your mouse to the desired start date.
  2. Click and drag the mouse to the desired end date.
  3. To return to the original graph, click Reset zoom.

Shutdown Server

Click Shutdown Server to completely shut down the Master Server.

This has the same effect as running shutdown -h now in the Master Server console. The Master Server may take a while to completely shut down.

Shutting down the Master Server also makes the Web Console unavailable. You need physical access to the Master Server to start it again.

Current scans and scheduled scans will continue to run while the Master Server is offline.

Password required to start Master Server

If full disk encryption was enabled when installing the Master Server, you have to enter the passphrase when starting the Master Server.

See Install the Master Server for more information.
