PCP Team,

Is there a specification (ASN.1 or otherwise) of the
PMCD-to-client protocol, which I might obtain?

I can assure you it is _not_ ASN.1 ... PCP is for analyzing performance
problems, not creating them ... 8^)>

The message protocol and format is not a secret

        pminfo -D pdu -v

will dump out the messages flowing in both directions between the
client and pmcd.

We don't have any documentation beyond that ... but more to the point
I'm kinda curious as to why you're interested in this, as the only
sensible way to use the infrastructure is via libpcp and there is
detailed documentation available on that API.

Roughly, each libpcp call maps onto 1 sent message and 1 received message.
