Using the Dynamic Group Rule Editor

This is the second dialog of the WhatsUp Gold Dynamic Group Builder. Use this dialog to create or edit rules for use in the SQL filter for the new group.

Select the desired rule components from the list and enter in a variable in the empty field.

This is a list of rule types available for use with the WhatsUp Gold Dynamic Group Builder.

String rules

• Active monitor. Checks the Active Monitors configured for a device found at Device Properties > Active Monitors.
• Device attribute. Checks for a device Attribute name that matches the criteria entered in Attribute value. Device attributes are configured on the Device Properties > Attributes dialog.
• Display name. Checks the Display name field found at Device Properties > General.
• IP address. Checks the IP address field found at Device Properties > General. Also checks any additional network interface in the Additional Network Interfaces dialog.
• Host name. Checks the Host name field found at Device Properties > General. Also checks any additional network interface in the Additional Network Interfaces dialog.
• Device type. Checks the Device type field found at Device Properties > General.
• SNMP OID. Checks the SNMP OID field found at Device Properties > Credentials.

You can choose from six search criteria for the string rule types:

• contains
• does not contain
• is
• is not
• starts with
• ends with

After choosing a search criteria, you enter a variable to complete the string rule. An example string rule could read, "Match the following rule where: Device type contains Windows," where "Device type" is the rule type, "contains" is the search criteria, and "Windows" is the variable. This string rule would search for all device types on the network that contain the word "Windows."

"Yes/No" rules

• Has an SNMP credential. Checks the SNMP v1/v2/v3 credentials field found at Device Properties > Credentials to see if devices have SNMP credentials.
• Has a Windows credential. Checks the Windows credentials field found at Device Properties > Credentials to see if devices have Windows credentials.

  Note: Does not apply to Passive Monitors that use credentials.

You have two search criteria to choose from for Yes/No rules:

• Yes
• No

You do not have to enter a variable for Yes/No rules, because the variable exists in the rule type itself. For example, if you're searching for devices that do not have SNMP credentials, the variable is the SNMP credential. The criteria is whether a device has an SNMP credential (No). An example yes/no rule could read, "Match the following rule where: Has a Windows credential, Yes," where "Has a Windows credential" is the variable and "Yes" is the search criteria. This rule would search for devices that have Windows credentials.

"IP address is within" rules

You can create two types of IP addresses within rules:

• the range
• a subnet

The range. To create a Dynamic Group consisting of devices within a certain range of IP addresses, you can create a rule that searches for devices with addresses that fall between two IP addresses, a lower number address, and a higher number address. For example, you could create a rule that reads, "Match the following rule where: IP address is within the range 192.160.1.1. and 192.165.25.255." The rule would search for all devices with IP addresses that fall between the two addresses and create a new Dynamic Group with these devices.

A subnet. To create a Dynamic Group consisting of devices within a certain subnet, you can create a rule that searches for devices on a specific IP address' subnet. You will be required to know an IP address and a subnet mask. You can either the subnet mask or the prefix length of that subnet in the Mask field.

Using the A subnet option requires that you have some knowledge of CIDR notation.

Note: The "IP address is within" rules do not support IPv6 addresses. A full rule should read something like, "Match the following rule where: IP address starts with 192.6."

Click OK to add the rule to the Dynamic Group Builder dialog.
