Applicable to Entuity v19.0 upwards. If you are using an earlier version of Entuity, please see this article.
You can use Auto Discovery to discover devices on your network and add them to management. Auto Discovery is most useful when you have many devices, or a potentially unknown set of devices, to manage.
This can be configured to continually scan your network, so that you always have an up-to-date, detailed inventory of network assets.
Individual discovery profiles allow you to specify the parameters of the Auto Discovery.
To create a discovery profile:
Navigate to the Discovered Assets page. Click Create Discovery at the top of the page or via the Overflow Menu.
This will open the New Discovery form on the right of the page.
- Enter a Name and Description for the discovery profile.
Note, the Discovery Scope functionality replaces the import devices via a device file (seed file) from earlier versions of Entuity.
- Specify the Zone in which to scan your specified IP address range. Please see this section for further help and information on Zones in Entuity.
- In the Addresses field, specify the device, range of IP addresses and/or IP subnets, or the hostnames for Auto Discovery to use when identifying devices for ENA to take under management. In the Exclusions field, specify those to exclude. You can include multiple rows of addresses, and on each row you can enter:
- A range of IP addresses, specifying the From and To values.
- An IP address or device name.
- An IP subnet, specifying the Prefix and Netmask values.
- Specify if you want to use all credentials, or specify an individual credential.
- If switched off, you can click the Credential field to specify the credentials to use. This will open the Credential form, from where you can either add + a new credential, or select one from the list. Please see article for help and information on creating a credential.
- Specify a schedule for when the profile will run. If switched on, you can specify the day and hour on which the profile will run.
- Specify if you want to Automatically Manage Discovered Assets. By default, this field is switched off.
- If switched on, you can then specify the management parameters:
- Management Level
- Port Management
- Display Name
- Poll Using
- If switched on, you can then specify if the assets are to be added directly to a View. If so, you can search for the desired View by clicking the View Path field.
Associated Asset Onboarding
- Specify if you want to Automatically Manage Associated Assets. Associated assets are the VM/SD/AP devices associated with a VM platform or other type of controller.
- Click the Advanced field to open the Advanced form.
- Switch on Use SNMP Bulk Get if you want to receive back multiple GetNext responses in a single packet. Leave the box unticked if you want to receive back the normal 1 GetNext response back.
- In the TCP Port List field, specify the list of ports that Entuity will probe to decide whether the port is up.
- Specify on which port the device's SNMP agent receives its requests, in the SNMP Port field. By default, this is set to the default UDP port 161.
- Specify the system object identifiers of devices that Entuity should not manage in the Excluded SysOids field. The default excluded SysOids are as follows:
- 184.108.40.206.4.1.3220.127.116.11.1.2 Windows Server
- 18.104.22.168.22.214.171.124.126.96.36.199.3 IBM PowerPC Personal Computer
- 188.8.131.52.4.1.8072.3.2.10 Net-SNMP Agent 5.1
- 184.108.40.206.4.1.8072.3.2.3 Solaris NetSNMP
- 220.127.116.11.4.1.318.104.22.168.1.1 Windows Workstation
- 22.214.171.124.4.1.3126.96.36.199.1.3 Windows Domain Controller
- 188.8.131.52.184.108.40.206.1.1 Solaris Server
Through discovery.HostNameFormat in entuity.cfg you can amend the device name format used by Entuity. By default Entuity attempts to poll a device using the qualified DNS device name, then an unqualified DNS device name and only then the device IP address.
- Specify if you want Entuity to perform WinRM discovery. By default, this is switched on.
- If enabled, specify the list of ports on which WinRM discovery will be performed.
- Specify if you want Entuity to perform SSH discovery. By default, this is switched on.
- If enabled, specify the list of ports on which SSH discovery will be performed.
