Discovery Administration

Configuring and managing the discovery system.

Discovery Configuration​

Global Settings​

  • Discovery intervals
  • Retry policies
  • Timeout settings
  • Concurrent scan limits

Credentials Management​

Configure secure credentials for discovery operations:

Windows Systems:

  • Domain credentials for enterprise environments
  • Local administrator accounts for workgroups
  • Password encryption for secure storage

Linux Systems:

  • SSH key-based authentication (recommended)
  • Username/password authentication
  • Sudo or root access for complete inventory

SNMP Devices:

  • SNMPv3 with authentication (recommended)
  • Configure authentication and privacy protocols
  • Community strings for SNMPv2c (legacy)

Discovery Ranges​

IP Range Configuration​

Define network ranges for discovery:

Corporate Network:

  • Network range: 192.168.1.0/24
  • Status: Enabled
  • Schedule: Every 4 hours

DMZ:

  • Network range: 10.0.0.0/24
  • Status: Enabled
  • Schedule: Daily at 2 AM

Exclusions​

  • Specific IPs
  • IP ranges
  • Device types
  • Critical systems

    type: "full"
    
  incremental:
    expression: "0 */6 * * *"  # Every 6 hours
    type: "incremental"
    
  real_time:
    expression: "*/15 * * * *"  # Every 15 minutes
    type: "changes_only"

On-Demand Discovery​
