It is now possible to configure a rule in WATO which limits the number of OIDs fetched by a check, for example the if/if64 check, which might then only fetch the information for some interfaces instead of all interfaces.
This is a performance optimisation feature which is only useful for special use cases. The OID ranges to fetch need to be specified manually and can only be configured for a small subset of checks where it makes sense to configure it. It applies only when using bulk walks with Inline-SNMP.
In case of the interface checks this rule might be useful when you have e.g. a network switch with several hundrets of interfaces and only want to monitor a small amount of the network interfaces, for example the first 10 interfaces.
