  3. 3. Trainer Sharath Babu Product Expert
  4. 4. Part 1 Discovery and classification
  5. 5. Agenda • Prerequisites for installing OpManager • Understanding network infrastructure • Challenges of device discovery • 5 important steps to simplify the discovery process in OpManager • Real-life use cases
  6. 6. Prerequisites for installing OpManager: System requirements Quad-core processor or higher • MSSQL • PGSQL 40GB8GB • Window s • Linux https://www.manageengine.com/network-monitoring/help/hardware-and-software- requirements.html
  7. 7. Protocol Ports SNMP 161 (UDP) SNMP Traps 162 (UDP) WMI 135 and 445, 5000 to 6000 (TCP) bidirectional Telnet 23 (TCP) SSH 22 (TCP) ICMP/TCP Used to check the availability status and add a device Syslog 514 (UDP) Web server (HTTPS/HTTP) 443/ 80 Prerequisites for installing OpManager: Ports

  11. 11. Challenges of device discovery
  12. 12. 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
  13. 13.  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 Challenges with importing devices from a CSV file
  14. 14. 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? SQL server Challenges in post-discovery jobs: Configurations
  15. 15. Challenges in post-discovery jobs: Interface discovery I only want to discover the ethernet interfaces from my switches. Can I select the required network interface type while adding the switch?
  16. 16. Network today Network after two weeks Schedule network discovery Discovery Reports Ensure devices added to the network are scanned successfully Challenges in automating device addition: Discovery Schedule
  17. 17. Important steps to simplify the discovery process in OpManager5 Quick demo
  18. 18. Real-life use cases
  19. 19. US A Colorado California Denver Aurora MilpitasSan Jose Rocheste r New York City New York Radio devices are installed in random locations every third week 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
  20. 20. Mail server SQL server FTP serverPrinter WEB server 192.168.49. 1 Network topology of Building D 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
  21. 21. AP I 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.
  22. 22. Device properties - IP address - RAM size - Hard disk size - Exchange version - Etc. Use case 4: Update interface/device properties with Discovery Schedule Interface properties - Name - Speed - Description - Admin/operational status - Etc.
  23. 23. Unknown Use case 5: How do I fix devices getting discovered as Unknown?
  24. 24. Top fixes for failure 1 2 3 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
  25. 25. We have added a new feather to our cap • Creating groups based on site, department, customers, etc • Threshold settings based on custom groups • Dashboard for groups and sub groups • Filters based on groups in widgets and reports Grouping
