the way you have passed value in prometheus.yaml is wrong

The gist of this error is that the version of binary used to generate the code isn't compatible with the current version of code. A quick and easy solution would be to try updating the protoc-gen-go compiler and the gRPC library to the latest version.

go get -u github.com/golang/protobuf/protoc-gen-go

then regen the proto

heres a link to a reddit thread that discusses the issue

Pay attention new version(v2.1.6) of treafik's request query to check pull data is:

Can i simulate a synchronous ReadFile operation but with a timeout, using GetOverlappedResultEx?

yes, you can, exactly like you and try already. and this is not simulation. this will be exactly synchronous file read. because synchronous read - this is asynchronous read + wait in place when I/O complete. so code can be next:

In this case there seems to be no purpose to the extra block. No variables are declared inside the block. It doesn't add clarity, instead it's confusing you.

If clarity were desired you'd extract that code into a new function to initialize the logger.

The problem is that you didn't add the severity level attribute. This attribute is normally provided by the logger, but you're using the logger_mt logger, which doesn't add any attributes and ignores the argument you provide to the BOOST_LOG_SEV macro. You should use severity_logger_mt or some other logger that provides support for severity levels. This logger will add the severity level attribute to every log record made through it and will set the level to the value you specify in the BOOST_LOG_SEV macro call.
