mongo stats and backup in C++

[Mick]

Are there any C++ commands to gather database stats and perform database backup/restore? 

I know there are plenty in the shell, but couldn't find anything for C++.  

Any help is greatly appreciated :)

Hi Mick,

There are no tools for backup in C++, you would be best looking at the mongodump and mongorestore applications.

Please have a look at our documentation for backup information http://www.mongodb.org/display/DOCS/Backups

As for gathering statistics you can normally run any command within C++ using the runCommand function, but without specifics of what you are looking for i cannot provide you with anything concrete.

As an example here is a short wrapper to get the dbstats of the test database:

BSONObj a = BSON("dbstats" << 1 << "scale" << 1 );

BSONObj ret;

c.runCommand( "test", a, ret);

Cheers,

David

Thank you, David, for your helpful and prompt response :)

I'm wondering if you can get mongo stats like average object size (avgObjSize in MongoVUE), dataSize, storageSize, maybe free space?

Thanks again :)

Actually, I spoke too soon in my previous post...  I just ran the runCommand and the result has all the information that I need, thank you very much for your help, David :)
