Introduction

These are the primary global settings for the software system. They include policy settings for user security, database retention limits, system profiles and database backup options. Please refer to the documentation before making changes because these settings can significantly alter the behaviour of the software,

Contents

System Settings

General

Disable System Scheduler: This prevents the scheduler from running which means all scheduled jobs are suspended until this this option is cleared. Schedules

Database Configuration

See Database Configuration

Tracks

Track Check Period (ms): How often the system checks for expired tracks.

Maximum Sightings: Maximum number of sightings stored of a single track - after which the system stops recording sightings.

Minimum Debris Sightings: Minimum number of sightings recorded before a track is classed as debris.

Minimum IFF Sightings: Minimum number of IFF (Friend or Foe) sightings definitely recorded as a track before potential culling. Given stationary tracks don't need to be recorded, IFF tracks will be culled when stationary, but the Minimum IFF Sightings ensures they are recorded first.

Last Sightings: Number of sightings guaranteed to be recorded at the end of a track.

Debris (and IFF) Movement Limit (m): Distance of movement below which debris (and IFF tracks) will not be recorded.

Use Radar NTP Time: This is the Network Time Protocol data sent with the tracks from the radar. NTP is a networking protocol for clock synchronisation between computer systems over packet-switched, variable-latency data networks.

Central Tracker Licencing

Enabled: This is where you enable central licensing documented here.

Alarm Options

Audible Alarm: Select to have a sound emitted when a system alarm is active.

Custom Threat Sound: The sound clip emitted for a threat alarm (this supports most common sound formats including .mp3 and .wav).

Custom Warning Sound: The sound clip emitted for a warning alarm (this supports most common sound formats including .mp3 and .wav).

Alarm Timeout (s): The length of time before the alarms are cleared after a system or AID alarm has been resolved.

Auto Acknowledge: Select if alarms are automatically acknowledged when they are cleared. If auto-acknowledge is disabled, then the operator is expected to acknowledge all alarm incidences. 

Clear Alarm Minimum Role: The minimum role in the role hierarchy that has permission to clear alarms. Any roles below this in the role hierarchy will not be able to clear alarms.

Mongo Index Options

System Logs Retention Days: How long system logs are maintained in the database before being deleted. 

Alarm Log Retention Days: How long alarm logs are maintained in the database before being deleted. 

System Profiles

Current Profile Name: The current profile in use.

Current Profile User ID: A user friendly Id that can be used for external control, associated with whomever created the profile. 

Please refer to System Profiles for more information.

Password Complexity

Required from Roles: Determines which roles will have a password that applies to this complexity.

The Roles are a hierarchy: 

  1. Administrator

  2. Engineer

  3. User

  4. System

A complex password will be required from not only from the role selected, but all roles above it in the hierarchy too.

Password Length: The minimum length of password required.

Min. Character Types: The minimum number of different character types needed to be in the password. There are four character types: abc, ABC, 123, @&(. If no password is required, both Password Length and Min. Character type values should be entered as '0'.

Archive Settings

Retention Days (days): The number of days a track with changed Analysis Status will be retained before being purged. By changing a track's Analysis Status (see Track Queries), the default purging is interrupted as the track is designated of 'special interest', and a new purge deadline can be set.

SSO Settings (Single Sign-On)

These settings enable Witness to check against an Active Directory / LDAP server for Users and Groups.

Enabled: Select to enable SSO.

Server: There are several options:

Legacy Domain Name

Domain Name

Server Name

Server IP Address

Server Name or IP Address with Port

Container: Can be a Common Name for searching within the directory.

Username: The User who can look up Users and Groups within the directory.

Password: The password of the User.
