Configuring Device Templates
OpManager comes with over 10000 device templates which carry the initial configurations to classify the devices into the pre-defined categories, and to associate monitors to them automatically upon device discovery. The device templates enables you to effect a configuration once and is applied to several devices at a time whenever there is a change. OpManager has unique device templates for almost every device type offered by major vendors. Click here to know more on the list of all available device templates.
The templates carry information required to classify the devices and to associate relevant monitors. You can further define your own templates and modify the existing ones.
Creating or modifying device templates
OpManager allows you to create a custom device template if needed. This option comes in handy when you cannot find a device template specific for a device in your network. Furthermore, you can also edit the presets in the existing device templates as per your environmental needs.
To create a new device template
- Go to Settings → Configuration → Device Templates.
- Click on the Add Template option.
- Fill in the key parameters parameters and click on Save. The changes will be automatically reflected for devices that match the specified SysOID on further discovery or upon rediscovery. The changes can also be manually associated once the template is saved.
Properties required to create a new device template
What does the Sync Device Template option do?
- Device Template Name: The device model name. This will be determined as the device model in the inventory list.
- Vendor Name: The vendor name of device. You can either select from the existing list of vendors or add a new vendor.
- Category: The category your device belongs in (server, desktop, WLC, storage devices, etc). This helps OpManager categorize similar device types together and organize better. You can either select from the existing list of categories or add a new one. Learn more about device categories.
- Monitoring Interval: The interval at which OpManger contacts the device for availability monitoring. You can also edit the monitoring interval of devices in bulk or category wise from the Quick Configuration Wizard under Settings. Learn more.
- Device Image: A image or icon that represent a particular device type. You can either select from the available set of icons or create a customized image.
- Device Identifier: Device identifier is a vendor's authoritative identification (sysOID) value to determine the device model. You can either manually add the sysOID or let OpManager fetch the value by querying the sysObjectID (.188.8.131.52.184.108.40.206) from RFC1213 MIB if the device is available in OpManager. If you are yet to add the device, you can query through the MIB Browser to identify the sysObjectID. How to query sysOID using MIB browser?
Note: Please note that every sysID should be unique and should not be repeated for multiple device categories or types. You will not be able to create two device templates with the same sysOID value. However, to differentiate similar devices with different templates, multiple sysOID criteria can be included while specifying the device identifier. For example, if a Linux Redhat and Linux Ubuntu device types hold the same SysOids, it can be classified using different sysOid criteria. Learn more.
- Associated Monitors: A set of monitors to be automatically associated with the devices during discovery. You can either
- Edit Thresholds: Helps you edit the thresholds values of the associated monitors. Select the monitor and edit thresholds to receive alerts and notifications accordingly.
- Associating templates: Once monitors are assigned and thresholds are set, you can further customize how it should reflect.
The 'Associate' option lets you apply the changes to monitors added in the future.
The 'Associate and Overwrite' option lets you overwrite the changes to all the existing monitors.
- Device templates are automatically associated to devices upon discovery. However, it can also be carried out manually post discovery if valid credentials are associated. Click here
to learn more.
- Device templates can also be imported from ManageEngine Support and Community Forums or from a different instance of OpManager. Click here to learn how.
- During discovery, if none of the device template match with the discovered device, OpManager creates a custom template by matching sysOID with the vendor template. This will only help in the availability monitoring of the device. No default monitors or device category will be associated and performance monitoring will not be initiated, unless done manually.
