To make device management easier and to automate bulk operations, Unimus uses a discovery mechanism.
The discovery mechanism works in stages:
- Detect available connector
All available ports for all enabled connectors are checked.
Secure connectors are always preferred to insecure connectors.
For example, if a device is available over both Telnet and SSH, SSH will be used.
- Detect credentials
All credentials configured in the 'Credentials' settings are checked against the device.
Credentials are checked against the device in random order.
Whichever credentials work on the device first will be used for any future operations with this device.
- Detect device vendor and model
After correct connector and credentials are known, Unimus discovers the device.
The Vendor, Type and Model of the device is discovered.
When is Discovery performed?
- Device addition into the system
The discovery mechanism is what makes only the address of the device required when adding a new device into Unimus.
Unimus will automatically discovered everything else about the device.
- Import
When 400 devices are imported into Unimus, Unimus will automatically discover all the necessary details about each of the devices, and start backing them up automatically.
If proper connectors and credentials are configured, no additional steps other than importing the devices are needed.
This saves time for the administrators, and automates the work-flow.
- Credential changes
Discovery mechanism will also be used if any device operation fails.
For example, if credentials which were previously used on a device are no longer valid on that device, Unimus will re-run discovery.
This means that if credentials used on 400 devices need to be changed, the only change needed in Unimus is to reconfigure the credentials in 'Credentials' settings.
Discovery mechanism will take care of the rest.
- Device hardware changes
Discovery will automatically be re-run when device hardware change is detected.
For example, when a Cisco device is replaced with a MikroTik, or a HP device with an UBNT device, Unimus will handle this automatically.
This means that if devices are changed around the network, Unimus will automatically adjust to the situation, without the need for user interaction.
How to find out why device didn't discover?
There are 2 places in Unimus where you can see why discovery failed.
- Dashboard > Latest failed jobs
You can select the discovery job, and press 'Show log'. - Logs
'/var/log/unimus' or 'C:\ProgramData\Unimus\log'
