Re: [pcp] JSON PMDA

Hi David,

Noticed a couple of little things when we were looking at that install
failure you saw recently...

            # pmParseUnitsStr() doesn't handle unicode
            utf8_units = units.encode("utf-8")

this has been resolved below the API since you encountered this I think,
so you should be able to safely remove that now and pass native strings
around directly.  Please let me know if not the case, cos there's a bug
lurking there still then.

Also, the strategy for generating pmids and indom ids ...

            self.__pmda.indom_idx += 1
            self.__metric_idx += 1
            self.cluster_idx += 1

... needs to be deterministic, else bugs - see mail re dmcache/dmthin a
little earlier for more details.  IOW, restarting/reconfiguring the PMDA
needs to ensure the same IDs are generated for the same metrics/indoms.

cheers.
