Getting started - Discovery

Device discovery is the first step towards monitoring your network using OpManager. For uninterrupted discovery process, ensure that the required ports are not blocked in your anti-virus application and Firewall. Learn more

Once installed, OpManager looks out for all the neighboring servers, and domain controllers in your network and add them into the OpManager Inventory.

However, to discover or add a device manually you need to follow the below steps.

  1. Add Credentials
  2. Discovery Configuration
  3. Add/Discover device

1. Add credentials

Access credentials are authentication details used by OpManager to access the remote device for monitoring and proper classification of your network devices. Based on your monitoring requirement, you can create the necessary credential for the required protocol.

You can find this under Settings -> Discovery -> Device credentials. Click here to learn more on the types of credentials supported in OpManager.

Note:

  1. Skip this step if you are looking only for availability monitoring (ICMP or TCP) and not performance monitoring. However, credentials are required if you wish to monitor availability via SNMP.
  2. Once credentials are added, you can test it with your network devices to ensure they are up to date.

2. Discovery Configuration

Device Template: These are templates with device type or model and pre-loaded configurations such as device type, category, monitoring interval and a set of performance monitors with corresponding thresholds. Once the correct credentials are applied, OpManager will automatically assign an appropriate device template based on the type and model of the discovered device. OpManager comes built-in with more than 10000 device templates with support for various custom templates as well.

You can find this under Settings -> Discovery -> Device credentials. Click here to learn more on the types of credentials supported in OpManager.

Discovery rule engine: This helps you automate activities such as adding the discovered devices into a specific group or Business view or in adding a specific set of monitors to a device during initial discovery.

You can find this under Settings -> Discovery -> Discovery Rule Engine.Learn moree.

Now, required credentials are added for device classification and a corresponding device template is configured with a default set of monitors. Now, the devices in your network can be added into OpManager for monitoring.

3. Add or Discover device

All required devices in your network can be scanned and added into OpManager individually or as bulk to initiate monitoring.

Individual device discovery: If you wish to discover a single device/server, you can use the 'Add Device/Server' option and perform a quick device addition by associating the required credential. Learn more.

You can find this under Settings -> Discovery -> Add Device/Server.

Discover devices as bulk: The 'Network Discovery' allows to discover or add devices in bulk by specifying the IP range, subnet, Active Directory login credentials or by uploading a CSV file that has necessary device information. Learn more.

You can perform bulk discovery under Settings -> Discovery -> Network Discovery.

You can also schedule the process of adding devices in OpManager using the Scheduled Discovery feature.

OpManager Inventory: The devices added in OpManager will be listed in a section called 'Inventory'. You can view all the devices, interfaces and groups that are part of your network here. Learn more.

Interface discovery: The interfaces associated with your network devices can also be monitored for its availability status and overall performance using OpManager. Metrics such as interface traffic, utilization can be monitored and reports can be generated for the same. Learn more.
