Setting DNS Lookups in the Target Editor
- To override DNS lookup at the target-level, first open the target in the Target Editor. If you're not sure of the target to modify, inspect your clip(s) in the Clip Editor lower panel, Message/Actions tab, Included Targets list (you can double-click an included target to open it in the editor).
- In the open target, locate the DNS Options section. The Target Editor > DNS Options section includes the ability to set a DNS server per target, and also to specify the lookup's Minimum and Maximum Time to Live (TTL), in the Target Editor.
- To use DNS lookups, check the "This Target performs its own DNS Lookups" box. Once enabled, CloudTest's Maestro DNS Caching layer will perform the lookup traversing from the top level domain and "down" until it can resolve the target's host name to the IP address it should communicate with. Note that this is not a must, just nice to have, and will work with all of the input boxes below left empty.Note: In most cases, it is not necessary to fill in the remaining DNS Server fields (unless the test case specifically requires one). See the DNS Lookup Considerations section above to determine if your test needs the additional settings specified.
Optionally, specify the following
settings.TIP: DNS lookups can be used in
conjunction with HttpHostOverride settings for environments where load balancing
architectures are in place.
- DNS Server
- DNS Maximum TTL
- Save the target after making any changes.
