Verbose control

[Mateus Pelicer]

Hi, 

I am trying to control the output Ceres shows when there are errors. 

I am starting glog with google::InitGoogleLogging(argv[0]); 

and then I define, where I'm testing the output.

class custom_solver_verbose : public google::LogSink {
public:

custom_solver_verbose() : debug(false) {};

virtual void send(google::LogSeverity severity, const char* full_filename,
const char* base_filename, int line,
const struct ::tm* tm_time,
const char* message, size_t message_len) override {
(void )full_filename;
(void )base_filename;
(void )line;
(void )tm_time;

std::string msg(message, message_len);
if (msg.find("Error in evaluating the ResidualBlock") != std::string::npos && !debug) {
return; // Ignore this specific message.
}

if (msg.find("Residual and Jacobian evaluation failed") != std::string::npos && !debug) {
return; // Ignore this specific message.
}
//
// // Log other messages as normal (example: to stderr).
std::cerr << "Custom Log: [" << severity << "] " << msg << std::endl;
}

void setup_verbose(bool debug){
this->debug=debug;
}

private:
bool debug;
};

This has worked until now, but when I have the output:

"E1207 14:42:26.501088 151361 trust_region_minimizer.cc:73] Terminating: Residual and Jacobian evaluation failed." I was unable to 'mute' it.

Is there any way to silence this output? Or to output it into a log file instead of the terminal?

Thanks.

Hi Mateus,

"E1207 14:42:26.501088 151361 trust_region_minimizer.cc:73] Terminating: Residual and Jacobian evaluation failed."

is generated by a 

LOG(ERROR) << "Terminating: Residual and Jacobian evaluation failed."

statement. So if your sink can grab messages at the error level you should be able to silence it.
