- Performance issues from bottlenecks/latency
- Overloaded links close to max capacity
- Suspicious traffic spikes indicating potential cyber threats
- Trends to inform future capacity planning
Key capabilities to look for:
- Customizable dashboards
- Dynamic visualizations
- Historical reports
- Configurable alerts
- Ability to set usage thresholds
- Range of integrations
Now let‘s explore 10 leading solutions that deliver these capabilities and more!
