When I implementing jaeger tracing it is unable to create a bucket.
(I m using swif to perform testing.)
/src/librados/IoCtxImpl.cc
```
void librados::IoCtxImpl::queue_aio_write(AioCompletionImpl *c)
{
std::cout<<"yes"<<std::endl;
JTracer tracer;
tracer.initTracer("Writing Started",
"/home/abhinav/Desktop/GSOC/deepika/ceph/src/librados/tracerConfig.yaml");
Span span=tracer.newSpan("writing started");
span->Finish();
try{
auto yaml = YAML::LoadFile("tracerConfig.yaml");
}catch(const YAML::ParserException& pe){
// ldout<<pe.what()<<dendl;
std::cout<<pe.what()<<std::endl;
ofstream f;
f.open("/home/abhinav/Desktop/err.txt");
f<<pe.what();
f.close();
}
// auto config = jaegertracing::Config::parse(yaml);
// auto tracer=jaegertracing::Tracer::make(
// "Writing",
// config,
// jaegertracing::logging::consoleLogger()
// );
// opentracing::Tracer::InitGlobal(
// static_pointer_cast<opentracing::Tracer>(tracer)
// );
// auto span = opentracing::Tracer::Global()->StartSpan("Span1");
get();
ofstream file;
file.open("/home/abhinav/Desktop/write.txt",std::ios::out | std::ios::app);
file<<"Writing /src/librados/IoCtxImpl.cc 310.\n";
file.close();
std::scoped_lock l{aio_write_list_lock};
ceph_assert(c->io == this);
c->aio_write_seq = ++aio_write_seq;
ldout(client->cct, 20) << "queue_aio_write " << this <<
" completion " << c
<< " write_seq " << aio_write_seq << dendl;
aio_write_list.push_back(&c->aio_write_list_item);
// opentracing::Tracer::Global()->Close();
}
```
/include/tracer.h
```
typedef std::unique_ptr<opentracing::Span> Span;
class JTracer{
public:
JTracer(){}
~JTracer(){
opentracing::Tracer::Global()->Close();
}
void static inline loadYamlConfigFile(const char* path){
return;
}
void initTracer(const char* tracerName,const char* filePath){
auto yaml = YAML::LoadFile(filePath);
auto configuration = jaegertracing::Config::parse(yaml);
auto tracer = jaegertracing::Tracer::make(
tracerName,
configuration,
jaegertracing::logging::consoleLogger());
opentracing::Tracer::InitGlobal(
std::static_pointer_cast<opentracing::Tracer>(tracer));
Span s=opentracing::Tracer::Global()->StartSpan("Testing");
s->Finish();
}
Span newSpan(const char* spanName){
Span span=opentracing::Tracer::Global()->StartSpan(spanName);
return std::move(span);
}
Span childSpan(const char* spanName,const Span& parentSpan){
Span span = opentracing::Tracer::Global()->StartSpan(spanName, {opentracing
::ChildOf(&parentSpan->context())});
return std::move(span);
}
Span followUpSpan(const char *spanName, const Span& parentSpan){
Span span = opentracing::Tracer::Global()->StartSpan(spanName, {opentracing
::FollowsFrom(&parentSpan->context())});
return std::move(span);
}
};
```
Output when trying to create new container
```
errno 111 connection refused
```
But when I remove the tracer part in IoCtxImpl.cc it is workng fine.
I m new to ceph, and dont know what information to share to correctly track
down the problem, if any extra informtion is needed I will share it
instantly.
Been stuck into this issue for one week.
Please someone help me!
Thank you.
