How can I ask icinga2 from the command line to execute a single-time check of everything?

I would like to test my whole system config. I think it is not a very unusual feature. I want icinga2 to check everything and show me the results. Ideally, notifications shouldn't be called, I only want to see the results in the standard output/stderr, but it would be also with notifications okay. Reasonable answers saying that there is no such feature without digging its source code, are also acceptable.
