About gathering agentless inventory from network devices

Inventory Solution

Inventory for Network Devices lets you gather agentless inventory data from the discovered SNMP network devices such as computers, network printers, network-attached storage devices, and network backup devices. To gather inventory, agentless tasks run on discovered devices and report the data to Notification Server. The data is stored in the Configuration Management Database (CMDB). You can configure the automated tasks that are scheduled to run at regular intervals to keep your inventory data current.

See About Inventory for Network Devices

When you configure agentless inventory tasks, you can specify the following:

  • Which devices to inventory

  • Which network protocols to use to communicate with the devices (connection profile)

  • When to run the task

You can create and configure agentless inventory tasks in the following ways:

Create a task with Agentless Inventory wizard.

The wizard guides you through the creation and configuration of agentless inventory tasks. You can later configure the advanced settings and schedules of a task on the task page.

See Creating agentless inventory tasks for network devices using the inventory wizard

Create a task manually

You can manually create tasks from the Agentless Inventory Tasks Web Part. This option lets you configure more advanced settings and schedules.

See Manually creating and configuring agentless inventory tasks

You can only gather inventory from the SNMP-enabled devices on your network that are already discovered. Run the Network Discovery task to discover your network devices and create resources for them in the CMDB. Make sure that the connection profile of the Network Discovery task has the SNMP turned on.

See About Network Discovery

Agentless inventory tasks use connection profiles to manage the protocols that are used to communicate with network devices. Connection profiles are components of the Symantec Management Platform. When a device is discovered, a resource for that device is created in the CMDB. The resource keeps a record of the protocols that were used to communicate with the device. Agentless inventory tasks automatically use the same protocols that were enabled when the device was discovered.

See Resource discovery methods

The process for gathering agentless inventory from network devices is as follows:

Table: Process for gathering agentless inventory from network devices

Step

Action

Description

Step 1

Discover network devices.

You can only gather inventory from the network devices that are already discovered.

See About Network Discovery

Step 2

Use SNMP data mapping tables to define how to map SNMP devices to the data that you want to gather.

SNMP data mapping tables identify the data fields that you want to gather inventory from and apply the settings to the selected device types.

See Working with SNMP data mapping tables

Step 3

Create and run agentless inventory tasks.

You create and schedule agentless inventory tasks to collect inventory. You can create the tasks either with inventory wizard or manually.

See Creating agentless inventory tasks for network devices using the inventory wizard

See Manually creating and configuring agentless inventory tasks

Step 4

View agentless inventory data.

You can view the gathered inventory data in the Resource Manager or on the Agentless Inventory page.
