Effective device discovery is a foundational step in building a robust monitoring environment in ScienceLogic SL1. This guide focuses on best practices when performing manual or guided discoveries via the SL1 user interface.
For a full overview of the discovery process, refer to the official documentation:

Key Best Practices
1. DNS Configuration
When discovering devices by hostname, ensure that DNS is properly configured and functional on the collector. Improper DNS settings can prevent successful device resolution and discovery.
2. Use CIDR Notation Thoughtfully
If you're using CIDR notation to define the discovery range:
- Stick with smaller ranges, such as /24, to limit the scope.
- Large CIDR blocks can overwhelm the discovery process and slow down the collector.
3. Avoid Overloading the Collector
Attempting to discover too many devices in one session can lead to performance degradation. A general rule of thumb (on a medium sized collector):
- SNMP: Up to 1,000 devices
- SSH (Linux): Around 500 devices
- PowerShell (Windows): Around 100 devices
💡 Tip: For large-scale discovery, distribute the workload across multiple collectors or collector groups.
4. Preview Discovery Results
Before running a full discovery session, run it with "Model Devices" deselected. This allows you to see what will be discovered without impacting device modelling or performance.
5. Test Credentials First
Always use the Credential Tester tool to validate new credentials before launching a discovery session. This ensures that:
- The collector can communicate with the target devices
- The credentials are correctly configured and accepted
