The document provides an overview of a training session on OpManager, detailing prerequisites for installation, challenges in device discovery, and important steps to streamline the process. It outlines various use cases, such as automating device addition through SNMP traps, discovering devices using router IPs, and integrating with ServiceNow. Additionally, it addresses common problems encountered during device discovery and offers solutions to ensure successful network scanning.

12. Challenges of device discovery

13. How to prepare for network discovery
1. Add admin users in OpManager
2. Ensure all devices are reachable from the
OpManager server
3. Add credentials for the respective device or
network

14.  Not all devices present in the CSV file need to be
monitored
 What happens if you import all the devices without
applying filters?
• Costs you a license
• Adds unnecessary load to the server

15. Task 3
Task 2
Task 1
Every time I add a SQL server, I set up the same set of
services, processes, and application monitors. How do I
automate this process?
I've grouped all MSSQL servers in a Business View for our
India site, and more servers will be added in the future.
Can I place these servers in the India group automatically?
I've set up a notification profile to trigger an email notification
for service down alarms. Can I assign this notification profile
automatically when a server is added?

Use case 1: Automate device addition by receiving SNMP trap
messages in OpManager
 Add multiple discovery profiles with possible network
range
 Enable device discovery via trap
• Settings > Discovery Settings > Discover devices
via Trap

Use case 2 : I don't have the complete list of
device details for Building D's network, but I know
the IP address of the seed router. Is there a way to
discover devices in OpManager using the router IP?
 Add a discovery profile using Layer 2
discovery
• Settings > Discovery Profile
> Layer 2 Discovery
Devices discovered through Layer 2 discovery
will have the dependent devices configured
automatically

22. AP

Use case 3: Adding devices from ServiceNow to OpManager
 Generate an API key for OpManager
• Settings > Rest API > Generate API Key
 Visit api.opmanager.com and get the API call for
adding a device, deleting a device, etc.

23. Device properties

Open the recommended port in your firewall
Visit https://www.manageengine.com/network-monitoring/help/hardware-and-software-requirements.html
for a list of recommended ports
Update the password in OpManager
- Settings > Discovery > Credentials
Test the credentials periodically and see when the test fails
- Settings > Discovery > Test Credentials
Create a new device template for the respective model
- Settings > Configuration > Device Template > Add Template
