Smokeping runs well for some month,but yesterday,it always show 502 error,I try to traceback but not found,then i debug for nginx error log that i found that
FastCGI sent in stderr: "[Thu Jun 20 01:16:59 2019] smokeping_cgi [client 66.249.79.179]: ERROR: slave 'dmit' is not defined in the '*** Slaves ***' section!" while reading response header from upstream, client: 66.249.79.179, server: myserver.com, request: "GET /?displaymode=n;start=2019-05-07%2004:30;end=now;target=america.us.level3sanjonse~dmit HTTP/1.1", upstream: "fastcgi://127.0.0.1:9007", host: "myserver.com"
that means the Google bot access a not exist page,then the server return 502 error and must be restarted by manually.
Why not 404 error but 502 error?
How can i avoid this error? because when an illegal user access the not exist page that means the whole master service will be halt on.

The right URI should be /?target=Globe
