ORBIT-USER: OML question

[Ramya Krishnamoorthy]

Figured out the problem. It was the single quotes. Changed it to
a.addMeasurement('createdObject', nil,
        [ ['objectName',String], ['majorVersion', 'int'],
['minorVersion','int'], ['size', 'int']] )

and it worked.

Thanks
Ramya

Hi

I have one more problem. I was able to generate the library successfully
using metric type "string".
But when I try to add a measurement in the application definition:
a.addMeasurement('createdObject', nil,
        [ ['objectName','string'], ['majorVersion', 'int'],
['minorVersion','int'], ['size', 'int']] )

I get an error running the experiment:
FATAL run: Exception: Unknown type 'string' for metric 'objectName'.
(RuntimeErr
or)
        /tmp/eee.199/lib/handler/appMeasurement.rb:121:in `addMetric'
        /tmp/eee.199/lib/handler/appMeasurement.rb:138:in `addMetric'

What am I doing wrong?

Thanks

Upto 32 character strings are supported.

Use type="string".
Check the header file you receive for the function declaration. You'll
have to use "char *" to pass your strings to OML. Works both with C and
C++ programs.
