With Auto Discovery, up.time can detect systems on your network that have an IP address within a specified range, as well as other search criteria:
pingutility is used to determine whether systems are available on the network
- an Agent check is performed to determine which systems have the up.time Agent installed on them
- a WMI check is used to determine whether Windows-based systems are using WMI to gather performance metrics
- SNMP-based network devices are detected
- an SNMP probe is done to find any systems that are using Net-SNMP
Systems that are repeatedly discovered with different checks (e.g., both an up.time Agent and WMI implementation are detected on the same system) will by default be assigned a type based on the first check that resulted in its discovery. The auto-discovery order is as follows: agent check, WMI check, network device discovery, Net-SNMP probe.
Once a list of systems in the range of IP addresses that you specified is generated, you can selectively add them to up.time.
Using Auto Discovery
To use Auto Discovery for systems and network devices, do the following:
- In the My Infrastructure panel, click Auto Discovery.
The Auto Discovery window appears.
- Ensure Auto Discovery is set for Servers and Network Devices, then click Next.
- Select one or more types of network entities to include in the auto-discovery process:
- Servers with up.time Agent
- Servers with Windows Management Instrumentation (WMI)
- Servers with Net-SNMP v2 or v3
- Network devices with SNMP
- Optionally provide up.time Agent connection information to allow the Monitoring Station to detect systems that have the Agent installed on them. Select the Use up.time Agent Global Configuration check box if this information has been configured (see Configuring Global Data Collection Methods for more information); otherwise complete the following options:
The port through which the up.time Agents communicate with the up.time Monitoring Station.
- Use SSL
Select this check box if the Agent securely communicates with the Monitoring Station using SSL.
- Optionally provide login information for an administrative Windows account if you would like Auto Discovery to scan for systems that are using WMI to collect metrics. Select the Use WMI Global Configuration check box if this information has been configured (see Configuring Global Data Collection Methods); otherwise complete the following options:
- Windows Domain (optional)
The Windows domain in which WMI has been implemented.
- User Name
The name of the account with access to WMI on the Windows domain.
The password for the account with access to WMI on the windows domain.
This option is only available on Monitoring Stations running on the Windows platform.
- Windows Domain (optional)
- Optionally provide SNMP connection information to allow Auto Discovery to scan for servers with Net-SNMP. Select the Use Global SNMP Connection Configuration check box if this information has been configured (see Global SNMP Configuration Settings for more information); otherwise select the SNMP Version that your servers are using, then complete the appropriate options:
- SNMP Port
The port on which the Net-SNMP instance is listening.
- Read Community
A string that acts like a user ID or password, giving you access to the Net-SNMP instance. Common read communities are public (enables you to retrieve read-only information from the device) and private (enables you to access all information on the device).
The name that is required to connect to the Net-SNMP instance.
- Authentication Password
The password that is required to connect to the Net-SNMP instance.
- Authentication Method (optional)
From the list, select one of the following options, which will determine how encrypted information traveling between the Net-SNMP instance and up.time will be authenticated:
MD5: A widely-used method for creating digital signatures used to authenticate and verify the integrity of data.
SHA: A secure method of creating digital signatures. SHA is considered the successor of MD5 and is widely used with network and Internet data transfer protocols.
- Privacy Password
The password that will be used to encrypt information traveling between the Net-SNMP instance and up.time.
- Privacy Type (optional)
From the list, select one of the following options, that determine how information traveling between the Net-SNMP instance and up.time will be encrypted:
DES: An older method used to encrypt information.
AES: The successor to DES, which is used with a variety of software that require encryption including SSL servers.
You can set both the authentication method and password types, only one of them, or neither.
- SNMP Port
- Optionally provide SNMP connection information to allow Auto Discovery to scan for SNMP-based network devices. Select the Use Global Connection Configuration check box if this information has been configured (see Global SNMP Configuration Settings); otherwise complete the configuration options as described in the previous step.
- For the Auto Discovery scan, in the Subnet field, indicate which subnets or IP address ranges to scan, using one of the following formats:
- a single subnet (e.g.,
- multiple, comma-separated subnet entries (e.g.,
10.1.50, 10.1.51, 10.1.52)
- an IP address range (e.g.,
multiple subnets and an IP address range (e.g.,
10.1.50, 10.1.51, 10.1.52,)
You may provide ranges only for address, but not subnets. Subnet ranges should be entered as a comma-separated series, as described above.
- a single subnet (e.g.,
- Select the Element Group in which these additions will be placed.
- Click Next to begin the auto-discovery process.
A list of the systems that match all your defined criteria is generated. The time required for the list to populate is dependent on the breadth of your search criteria.
- When the auto-discovery list has been completed, select the corresponding check boxes for all the network entities you wish to add to up.time as monitored Elements.
Click Next to begin adding your selections.
As your selections are added to up.time as Elements, the progress of their addition is displayed.
If this process is not fully completed, none of the queued network entities become up.time Elements.
All of the new Elements will appear in the selected Element group under My Infrastructure.
