Instrumentations SHOULD use error code such as one of errors reported by
|
|
`getaddrinfo`([Linux or other POSIX systems](https://man7.org/linux/man-pages/man3/getaddrinfo.3.html) /
|
|
[Windows](https://learn.microsoft.com/windows/win32/api/ws2tcpip/nf-ws2tcpip-getaddrinfo)) or one reported by the
|
|
runtime or client library.
|
|
If error code is not available, the full name of exception type SHOULD be used.
|
|
examples: ["host_not_found", "no_recovery", "java.net.UnknownHostException"]
