Auto-discovering

SNMP

SNMP, meaning Simple Network Management Protocol, provides a comprehensive capabilities to identify and track physical and logical components, and their relationship inter-dependencies.

SNMP is a universal software which once installed on your devices and combined with your EasyDCIM proves to be an optimal solution.

In other words, SNMP managed devices are scanned and the results are transfered directly to your EasyDCIM database.

It is a protocol that is responsible for exchanging, managing and monitoring information between network devices and EasyDCIM.

We are aware that it is extremely difficult to manage large networks with let’s say hundreds of items. In order to avoid the need to hire additional staff you may now monitor every device with one application only!

How It Works

The easiest way to add a new device to EasyDCIM is “Auto-discovering” tool. Basically, it is a process that is triggered by an administrator of EasyDCIM. Auto-discovering allows you to discover basic information about a device such as:

  • operating system
  • model of device
  • type of device
  • device status
  • information about network interfaces
  • information about power outlets
  • information about sensors
  • information about device uptime
  • information about location
  • information about processors
  • information about disks
  • information about RAM
  • information about printers
  • information about rest peripherals
  • information about network cards

It is meant to first of all detect any device that should be visible in your EasyDCIM, connect and transfer all possible data straight from the device to a data center.

You can go to the form from many places throughout the system. For example you can choose Infrastructure → Servers → Auto-discovering from the sidebar menu.

By default, auto-discovering form is based on the SNMP protocol. Minimal configuration requires only three parameters. These are:

  • Hostname or IP Address
  • SNMP Version
  • SNMP Public Community (or Security Name)

Of course, if configuration of SNMP protocol in the device is more advanced, we are able to choose a few additional options of SNMP configuration in version 3, such as:

  • Security level
  • Auth Protocol
  • Auth Passphrase
  • Priv Protocol
  • Prov Passphrase

After adding access data to SNMP, EasyDCIM system will try to automatically discover the device information. The system checks validity of SNMP connection basing on the following OID in SNMP tree: SNMPv2-MIB::sysObjectID.0. When value is downloaded, the system will recognize whether SNMP connection is valid, if not, it will display an appropriate error. If connection is established properly, only the basic information about the device are going to be downloaded and saved, such as:

  • operating system
  • model of device
  • type of device
  • label based on sysName value

The rest of the data is going to be downloaded after some time during realization of queuing process. The values concerning the access data are going to be automatically saved into the device settings so that they can be reused in auto discovering or polling process.

CIDR Discovering

In the ‘Hostname or IP Address or CIDR Subnet’ field, you can enter the IPv4 subnet address in CIDR format. Thanks to this, the system will perform discovering of all IP addresses in this subnet. Discovering of devices in a given subnet will be divided into appropriate tasks, which can be found in the ‘Discovery Jobs’ tab. Tasks are started automatically from the first address of a subnet to the last. The task status determines whether a device has been found on a given IP address using SNMP. If connection has been established, the device will be automatically added to the system. Otherwise, the system will return an error.
