Many monitoring tools return time-series data, like:

<timestamp1> <value1>
<timestamp2> <value2>

etc.

I think that instead of developing and installing multiple monitoring 
points (MPs) for individual monitoring tools (ping, owamp, etc.), it may 
be convenient to have a single MP that can call and retrieve results from 
an arbitrary monitoring tool.

Clearly some monitoring tools require richer semantics of requests and 
queries. But for many simple monitoring tools it is sufficient to have
one common MP to access them.

You may look at example requests and responses included in CMP. Any tool 
can be called with any arguments locally or remotely.

Regards,

Sven
