Description
The function mg_get_connection_info() returns statistics information collected for
a server connection index. This may be empty if the server has not been built with
statistics support (#define USE_SERVER_STATS).
If data is available, the returned string is in JSON format. The exact content may
vary, depending on the connection state and server version.
Note
This is an experimental interface and may be changed, replaced
or even removed in the future. Currently the index idx must be
between 0 and num_threads-1. The thread is not locked for
performance reasons, so the information may be inconsistent
in rare cases.
