Read about how to keep NetCrunch running smoothly over time, how to upgrade it and keep your network information up to date.
In this chapter
- TroubleshootingExplaining aspects that are not seen but taken care of. Use these tips to optimize your NetCrunch resilience.
- BackupNetCrunch automatically creates data backups each day. What a backup contains, whether it is encrypted, and what it can be restored onto all depend on the same thing: the credentials inside it.
- License ManagementLicense installation options described.
- NetCrunch DatabasesNetCrunch uses several specialized databases to efficiently manage configuration, event history, real-time status, long-term metrics, and documentation. Each database is optimized for its specific role in the monitoring platform, allowing NetCrunch to scale from hundreds to thousands of nodes while ensuring high performance.
- Auto DiscoveryThe primary NetCrunch goal is to keep all your network data up to date. This also includes network nodes and virtual machines.
- Update, Migrate and BackupLearn how to perform NetCrunch updates, migrate it to other machines, or set up a backup.
- RestartingRead restart recommendations.
- NCCLI NetCrunch UtilitiesYou can use NCCLI to execute commands served by the NetCrunch Server
- Advanced & experimental featuresExperimental workarounds for unusual situations - among them calculating node status from sensors instead of network services, for nodes that cannot be reached normally.
- Atlas Configuration UpgradeAn atlas created in an older version keeps the predefined monitoring packs and views it was born with. The upgrade brings those up to the current release without touching anything you configured yourself.
- When the Atlas Cannot Be LoadedIf NetCrunch cannot open the atlas at startup it does not simply fail. It offers three recovery options in order of how much you stand to lose: open it again, restore it from a backup, or delete it and start over.
