How do I run a network discovery?
- Before configuring/starting a discovery, make sure you have supplied appropriate credentials for routers, switches, servers, VMware, etc. This is done via Administration -> Other -> Shared Credentials:
- Use the "+" icon create new credentials. There should be at least one SNMP credential for community "public" with suggested name "Public Community". Create additional SNMP credentials for other community that are used in the target network
- Create at least one for Windows servers (WMI) with domain admin credentials. Finally, create one for VMware if applicable.
- Now proceed to create discovery job via Administration -> Discovery. This can be a one time or recurring, but make sure to select the right location where the DGEx is located
- Pay extra attention to the network scope. If the entry is not correct, the discovery will not yield any results. You must specify the network address and the subnet mask. If output of "ipconfig" shows the DGEx has address 172.17.17.9 with mask 255.255.255.0 and the gateway address is 172.17.17.1, the network address is 172.17.17.0 - not 172.17.17.1 or 172.17.17.9. It may be helpful to consult one of the many publicly available subnet/mask calculators.
- Make sure that the SNMP credentials that you created before are pre-selected and option to determine topology is also enabled under Advanced section
- Once settings look right, go ahead and click on Apply. The job will get scheduled and will start running on the DGEx shortly. Use the refresh icon to check status until the new job shows SCHEDULED to RUNNING
- Click on the discovery job and use the History tab to see progress of the session
- Once it is complete, the Network tab will show devices that were found. You can select one or more of these (select all option coming soon) and click the button below to provision them for monitoring in Traverse
- Navigate to Administration -> Devices and you will see the newly provisioned devices. Some of the devices will show a circular icon indicating they are being scanned to find what metrics to monitor. This process will take a few minutes to cover all the newly created devices
- Assuming the right SNMP community for routers and switches were provided and the device responded to queries (ie. no firewall/ACL in the way), you should see the topology information via Status -> Panorama
There you have it!
