Possible to identify a connection for logging purposes (C++)

[Saj]

I'm using a ScopedDbConnection from a pool. I would like to log the connection's identity to my application log so I can tie it back to mongod log.

Is there a getId() or similar method I could use (can't see one in the docs)?

Thanks,

Saj

Referring to https://groups.google.com/forum/?fromgroups=#!topic/mongodb-user/Iq2vdlUEYwg, you can write something like

#include <iostream>

#include <mongo/client/dbclient.h>

using namespace mongo;

int main() {

    try {

        DBClientConnection c;

        BSONObj o;

        c.connect("mongohostname:12345");

        c.simpleCommand( "admin", &o, "whatsmyuri" );

        cout << "connected ok on " << o.getField( "you" ) << endl;

    } catch( DBException &e ) { 

        cout << "caught " << e.what() << endl;

    }   

    return 0;

}

where instead of DBClientConnection c, you'd use myScopedDbConnection.conn().  This will report the connection's URI, which you can then correlate to the mongod logs.
