When deciding what to monitor (the monitoring parameters) and how frequently to monitor (the monitoring intervals), you may want to consider the device’s type and the device’s function in the network e.g. a Cisco 7600 series router sitting at network periphery will need to have both availability and bandwidth utilization monitored in contrast to a distribution switch whose availability needs to be monitored more importantly than bandwidth utilization.
It becomes unmanageable if you were to configure monitoring parameters and intervals to every device individually when you have hundreds of devices in the network. OpManager considers this and brings to the IT administrator ‘Device Templates’ which contain a pre-defined set of monitoring parameters and monitoring interval that are specific to a particular device type.
OpManager supports more than 8000+ device types out-of-the-box with every device type having an exclusive template.
Device type is the classification of devices by comparing the SysOID of each device with the available device templates.
Apart from default templates, you can also create custom templates or import them from the OpManager Forums.
Category is the grouping of devices having similar infrastructure properties. This facilitates easy monitoring and management of devices.
By default, OpManager comes with 18 categories, which are as follows :
Apart from these default set of categories, you can also create custom categories by inheriting the properties from the above said parent categories. Follow the steps below to create a custom category:
You can also add a category by going to Settings -> Basic Settings -> Categories -> Add Category
