<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Add an Auto-Discovery Group

There are several ways to manually add an auto-discovery group:

  • Select Devices | Add Auto-Discovery Group from the main menu bar. A dialog appears that guides you through the process of starting an automatic detection of devices and sensors in your network.
  • Hover over b_add and select Add Auto-Discovery Group from the menu.
  • Select Add Auto-Discovery Group from the context menu of the probe or group to which you want to add the new auto-discovery group. This skips step 1 and leads you directly to step 2.

i_round_blueThis documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.

i_podYou cannot use this feature on the hosted probe of a PRTG Hosted Monitor instance. You can use this feature on remote probes.

In this section:

Add an Auto-Discovery Group

Once the auto-discovery is finished, PRTG creates a new ticket and lists the device templates that it used to create new sensors.

Schedule

Select when PRTG runs the auto-discovery:

  • Once (default): Run the auto-discovery only once. PRTG adds new devices and sensors once. If you select this option, you must manually start the auto-discovery.
  • Hourly: Run the auto-discovery for new devices and sensors every 60 minutes.
    i_round_redUse this option with caution. Frequent auto-discoveries might cause performance issues, in particular when PRTG scans large network segments every hour.
  • Daily: Run the auto-discovery for new devices and sensors every 24 hours. The first auto-discovery runs immediately. All other discoveries start at the time that you define in the Monitoring settings, section Auto-Discovery.
  • Weekly: Run the auto-discovery for new devices and sensors every 7 days. The first auto-discovery runs immediately. All other discoveries start at the time that you define in the Monitoring settings, section Auto-Discovery.

i_round_blueFor performance reasons, PRTG sets Schedule to Once (default) on all devices that the scheduled auto-discovery creates.

Auto-Discovery Scanning Method

Select how you want to define the IP address range for the auto-discovery:

  • Class C base IP address with start/end (IPv4) (default): Enter an IPv4 class C address range.
  • List of individual IP addresses and DNS names (IPv4): Enter a list of individual IPv4 addresses or Domain Name System (DNS) names.
  • IP address and subnet (IPv4): Enter an IPv4 address and subnet mask.
  • IP address with octet range (IPv4): Enter an IPv4 address range for every IP octet individually. With this, you can define very customizable IP address ranges.
  • List of individual IP addresses and DNS names (IPv6): Enter a list of individual IPv6 addresses or DNS names.
  • Use computers from the Active Directory (maximum 1000 computers): Search in the Active Directory for computers to perform the auto-discovery.
    i_round_blueMake sure that you specify your Active Directory domain in the Core & Probes settings.

i_round_redPRTG can only discover subnets with up to 65,536 IP addresses. If you define a range with a higher number of addresses, the discovery stops before it is completed.

IPv4 Base

This setting is only visible if you select Class C base IP address with start/end (IPv4) (default) above.

Enter a class C network as the IP base for the auto-discovery. Enter the first three octets of an IPv4 address, for example, 192.168.0.

IPv4 Range Start

This setting is only visible if you select Class C base IP address with start/end (IPv4) (default) above.

Enter the IP octet of the class C network (specified above) from which PRTG starts the auto-discovery. This completes the IP base to an IPv4 address. For example, enter 1 to discover from 192.168.0.1 onwards.

IPv4 Range End

This setting is only visible if you select Class C base IP address with start/end (IPv4) (default) above.

Enter the IP octet of the class C network (specified above) at which PRTG stops the auto-discovery. This completes the IP base to an IPv4 address. For example, enter 254 to discover up to 192.168.0.254.

IPv4/DNS Name List

IPv6/DNS Name List

This setting is only visible if you select List of individual IP addresses and DNS names (IPv4) or List of individual IP addresses and DNS names (IPv6) above.

Enter a list of IP addresses or DNS names that the auto-discovery scans. Enter each address on a separate line.

IPv4 and Subnet (IPv4)

This setting is only visible if you select IP address and subnet (IPv4) above.

Enter an expression in the format address/subnet, for example, 192.168.3.0/255.255.255.0. You can also use the short form like 192.168.3.0/24. If you want to include multiple addresses and subnets, enter them as a list separated by a comma, for example, 192.168.3.0/255.255.255.0, 192.169.0.0/255.255.255.0. PRTG scans the complete host range (without network and broadcast address) that is defined by the IP address and the subnet mask.

IP Address with Octet Range

This setting is only visible if you select IP address with octet range (IPv4) above.

Enter an expression in the format a1.a2.a3.a4, where a1, a2, a3, and a4 are each a number between 0-255, or a range with two numbers and a hyphen like 1-127. PRTG calculates all permutations of all ranges. For example, 10.0.1-10.1-100 results in 1,000 IP addresses that PRTG scans during the auto-discovery.

Organizational Unit

This setting is only visible if you select Use computers from the Active Directory (maximum 1000 computers) above.

Enter an organizational unit (OU) to restrict the Active Directory search to computers that are part of this OU. For top-level OUs, use the distinguished name (DN) format without OU= and without the domain components (DCS). If you leave this field empty, there are not any restrictions.

Example:

  • For the DN OU=Domain Controllers,DC=example,DC=com, enter only Domain Controllers.

If you have sub-OUs, use the DN format without the leading OU= and without the DCS.

Examples:

  • For the DN OU=webserver,OU=production,DC=example,DC=com, enter only webserver,OU=production.
  • For the DN OU=intranet,OU=webserver,OU=production,DC=example,DC=com, enter only intranet,OU=webserver,OU=production.

i_round_blueMake sure that the OU contains computer accounts. If the OU is empty, you receive an error message.

i_round_redDo not enter the domain components. PRTG automatically uses the domain components from the domain name you enter in the Core & Probes settings.

Name Resolution

Select how to monitor newly discovered devices. This only affects new devices. This does not change the setting for other devices. Depending on your selection, the IP Address/DNS Name field of an added device shows the DNS name or IP address that PRTG uses to access the target device:

  • Use DNS names (default): Monitor newly discovered devices via their DNS names (if available) We recommend that you use this option.
  • Use IP addresses: Monitor newly discovered devices via their IP addresses.

i_round_blueThis setting does not affect how PRTG shows the devices in the device tree.

Handling of Already Known Devices

Select how to handle known devices:

  • Skip auto-discovery for existing devices/IP addresses (default): Do not rescan existing devices or IP addresses. PRTG only adds devices with new IP addresses or DNS names. PRTG does not add devices that that already exist in your configuration for example, in other groups. We recommend that you use this option.
  • Perform auto-discovery for existing devices/IP addresses: Rescan devices that have existing IP addresses with every auto-discovery. PRTG adds devices that already exist in other groups to this group and runs the auto-discovery on the newly added devices.
    i_round_blueThe auto-discovery does not run on devices that already exist in the group. If you want to run the auto-discovery for these devices, you must manually start the auto-discovery on them.

i_round_blueIn certain cases, the IP resolution might not work and might result in PRTG not adding a device if it has the same local IP address as it does in a different LAN.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

  • Reuse a session for multiple scans (default): Select this option if you want a VMware sensor to reuse a single session for multiple sensor scans to query data. With this option, the sensor does not need to log in and out for each sensor scan. We recommend that you use this option because it reduces network load and log entries on the target device. This can increase performance.
  • Create a new session for each scan: If you select this option, PRTG does not reuse a session and a VMware sensor has to log in and out for each sensor scan. This can decrease performance.

Credentials for SNMP Devices

Click b_inherited_enabled to interrupt the inheritance.

i_round_blueThe settings you define in this section apply to the following sensors:

Credentials for SNMP Devices

Credentials for SNMP Devices

Setting

Description

SNMP Version

Select the Simple Network Management Protocol (SNMP) version for the connection to the target SNMP device:

  • SNMP v1: Use SNMP v1 for the connection. SNMP v1 only offers clear-text data transmission.
    i_round_redSNMP v1 does not support 64-bit counters. This might result in invalid data when you monitor traffic via SNMP.
  • SNMP v2c (default): Use SNMP v2c for the connection. SNMP v2c also only offers clear-text data transmission but it supports 64-bit counters.
  • SNMP v3: Use SNMP v3 for the connection. SNMP v3 provides secure authentication and data encryption.
    i_round_redSNMP v3 has performance limitations because of the use of encryption. The main limiting factor is CPU power. Also keep in mind that SNMP v3, unlike SNMP v1 and v2c, does not scale with more CPU power. Because of this limitation, PRTG can only handle a limited number of requests per second so that you can use only a limited number of sensors using SNMP v3. If you see an increase in Interval Delay or Open Requests with the Probe Health sensor, distribute the load over multiple probes. SNMP v1 and SNMP v2c do not have this limitation.

Community String

This setting is only visible if you select SNMP v1 or SNMP v2c (default) above.

Enter the community string of your device. This is like a clear-text password for simple authentication.

i_round_blueWe recommend that you use the default value.

Authentication Method

This setting is only visible if you select SNMP v3 above.

Select the authentication method:

  • MD5 (default): Use message-digest algorithm 5 (MD5) for authentication.
  • SHA: Use Secure Hash Algorithm (SHA) for authentication.
  • SHA-224: Use SHA-224 for authentication.
  • SHA-256: Use SHA-256 for authentication.
  • SHA-384: Use SHA-384 for authentication.
  • SHA-512: Use SHA-512 for authentication.

i_round_blueIf you do not want to use authentication but you need SNMP v3, for example, because your device requires context, you can leave the Password field empty. In this case, PRTG uses SNMP_SEC_LEVEL_NOAUTH and it entirely deactivates authentication.

i_round_redThe authentication method that you select must match the authentication method of your device.

User Name

This setting is only visible if you select SNMP v3 above.

Enter the user name for access to the target SNMP device.

i_round_redThe user name that you enter must match the user name of your device.
