Using Device Templates

During initial discovery, OpManager DE categorizes the network devices into servers, printers, switches, routers and firewalls. For proper classification, install and start the SNMP agent on all the managed devices.

OpManager DE comes with over 500+ device templates which carry the initial configurations to classify the devices into the pre-defined categories, and to associate monitors to them. The device templates enables you to effect a configuration once and is applied to several devices at a time whenever there is a change.

The templates carry the information required to classify the devices and to associate relevant monitors. You can define your own templates and modify the existing ones. Devices templates can be created/modified only from the Central web client.

Creating/Modifying Device Templates
  1. From Central web client, go to Admin-> Device Templates.
  2. Click on New Template. New Device Template page opens.

  3.  Configure/modify the following properties.
    1. Device Template: Specify the device template name.
    2. Vendor Name: Select the vendor. Click New to add a new vendor, and Save.
    3. Category: Select the category for the device type. On discovery, the devices are automatically placed in the selected Category map.
    4. Monitoring Interval: Configure the interval at which the device needs monitoring.
    5. Device Image: Select the image for this device type.
    6. System OID: Type the sysOID and click Add.
    7. Add Monitor: Click this option to select the monitors.
    8. Edit Thresholds: Click this option to edit thresholds.
  4. Click on Create button to create the new device template.
The classified devices are placed under different maps for easy management. For proper device classification, make sure you have installed and started SNMP in all the network devices before starting OpManager DE service.

The default maps include:
  • Servers
  • Routers
  • Desktops
  • Switches
  • Firewalls
  • DomainControllers
  • Wireless
  • Printers
  • UPS
  • URLs
You can also add your own infrastructure views. Custom infrastructure views can be added to group devices which cannot be classified under the default views provided. For instance, if you would like to monitor some IP Phones, it will not be appropriate to classify them as servers or desktops.

This initial classification may not be accurate if

  • the network devices do not support SNMP.
  • some devices have their SNMP settings different from those specified in the Credential Settings.
