DNS probe
DNS probes determine the DNS names for configuration items (CI).
The default DNS Name Resolver probe is a lightweight and fast probe. It achieves its speed by executing in parallel on the MID Server. The probe utilizes DNS lookup by the MID Server host OS to make use of the maintained DNS cache. The probe also leverages the hosts file on the OS.
These performance improvements can be disabled by reverting to the legacy DNS probe with either MID Server properties or parameters. The names of the MID Server properties/parameters are [mid.probe.use_legacy_forward_dns] and [mid.probe.use_legacy_reverse_dns]. For more information, see MID Server parameters and MID Server properties.
