Starting a UDP Protocol DNS latency test
FortiTester tests the latency of the DUT while handling DNS query requests. The DUT could be a gateway device or a DNS server. This test traffic sends DNS requests to a DNS server and measures latency.
To start a DNS test:
- Go to Cases > Performance Testing > Protocol > UDP > DNS Latency to display the test case summary page.
- Click + Create New to display the Select case options dialog box.
- In the popup dialog, for the Network Config option, select the network template you have created in Cases > Security Testing > Objects > Networks. Then the network related options will automatically be filled. See Using network configuration templates for how to create a network template.
- Select a Certificate Group if applicable.
- Click OK to continue.
- Configure the test case options described below.
- Click Start to run the test case.
FortiTester saves the configuration automatically so you can run the test again later. You can also click Save to save the test case without running it.

Tip 1: You can also copy an existing case, and change its settings to create a new case. In the case list, click Clone to clone the configuration. Only the case name is different from the original case. Tip 2: You can add or edit a comment when the test is running. This comment can be used to search for the test result in the Results page. This is useful especially when the test runs for a long time. |
Protocol Test Case common options
Protocol Test Case configuration specific to DNS Latency Test
| Settings | Guidelines |
|---|---|
| Load | |
| Time Out | The default is 1000 microseconds. |
| Renew Socket | Specify Yes or No. If Yes, the client side renews a socket to send out the next query (note if the client profile “Domain Policy” is set as List, all queries for the names in the domain list will use the same socket; after that a new socket will be created for next batch of queries). If No, use the old socket. |
| Client Profile | |
| Domain Policy | Random or List. If Random is selected, FortiTester generates random domain names for queries. If List is select, FortiTester uses queries in the specified list. |
| Random Length | Specify the random length of the domain policy. |
| Domain | If Domain Policy is List, specify a list of domain name records. For example:
fortinet.com:A,www.fortinet.com:A,
A name followed with a “:A” means it’s an address record, while a “:MX” means a mail exchange record. |
