Building Rule Sets for Device Detection

Rules tab of the Roles wizard provides building blocks used to build a table of device detection rules. For example, you can combine detection rules to build an expression that excludes and/or checks for specific management objects (SNMP, WMI), system characteristics, or host attribute values.

Tip: As a practical guide for choosing and combining device detection rules, you can browse default rule sets (rules shipped within WhatsUp Gold). You can find more detailed rule sets applied in default sub roles.

• Add Rule. Apply a rule from the drop down list (you can also choose a negative match of the rule with ).
• Edit Rule. Edit a selected detection rule.
• Copy. Copy a selected detection rule.
• Delete. Remove a selected detection rule.

  Important: Creating many role definitions with large rule set expressions can have an impact and slow discovery and refresh scan performance.

Examples

• Match UPS manufacturer strings such as "MGE UPS SYSTEMS" or "MGE Office Protection Systems."

  SNMP object '1.3.6.1.2.1.33.1.1.1' (upsIdentManufacturer) contains 'MGE'

• Match specific NETAPP device using the asset tag.

  SNMP object '1.3.6.1.4.1.789.1.25.2.1.6' (nodeAssetTag) contains '02040'
