       pmnscomp - compile an ASCII performance metrics namespace into binary format.


       pmnscomp [-d] [-f] [-n namespace] [-v version] outfile


       pmnscomp  compiles  a  Performance  Metrics  Name Space (PMNS) in ASCII format into a more
       efficient  binary  representation.   pmLoadNameSpace(3)  is  able  to  load  this   binary
       representation significantly faster than the equivalent ASCII representation.

       If outfile already exists pmnscomp will exit without overwriting it.

       By  convention,  the  name of the compiled namespace is that of the root file of the ASCII
       namespace, with .bin appended.  For example, the root of the default PMNS is a file  named
       root and the compiled version of the entire namespace is root.bin.

       The options are;

       -d   By  default  the PMNS to be compiled is expected to contain at most one name for each
            unique Performance Metric Id (PMID).  The -d  option  relaxes  this  restriction  and
            allows  the  compilation  of  a PMNS in which multiple names may be associated with a
            single PMID.  Duplicate names are useful when a particular metric  may  be  logically
            associated  with  more  than  one  group of related metrics, or when it is desired to
            create abbreviated aliases to name a set of frequently used metrics.

       -f   Force overwriting of an existing outfile if it already exists.

       -n   Normally pmnscomp operates on the default PMNS, however if the -n option is specified
            an alternative namespace is loaded from the file namespace.

       -v   By  default,  pmnscomp  writes  a version 2 compiled namespace.  If version is 1 then
            pmnscomp will write a version 1 namespace which is similar to version 2, without  the
            extra integrity afforded by checksums.  Note that PCP version 2.0 or later can handle
            both versions 1 and 2 of the binary PMNS format.

       The default input PMNS is found in the file $PCP_VAR_DIR/pmns/root unless the  environment
       variable PMNS_DEFAULT is set, in which case the value is assumed to be the pathname to the
       file containing the default input PMNS.


       Once the writing of the new outfile has begun, the signals SIGINT, SIGHUP and SIGTERM will
       be ignored to protect the integrity of the new file.

                 compiled version of the default PMNS, when the environment variable PMNS_DEFAULT
                 is unset
                 some standard macros for PMID generation


       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names used by PCP.  On each installation, the file /etc/pcp.conf contains the local values
       for these variables.  The $PCP_CONF  variable  may  be  used  to  specify  an  alternative
       configuration file, as described in pcp.conf(4).


       pmnsadd(1),   pmnsdel(1),   pmnsmerge(1),   PMAPI(3),   pmLoadNameSpace(3),   pcp.conf(4),
       pcp.env(4) and pmns(4).


       Cannot open ``xyz'' -  the  filename  for  the  root  of  the  PMNS  that  was  passed  to
       pmLoadNameSpace(3) is bogus.

       Illegal PMID - either one of the three PMID components (see pmns(4)) is not an integer, or
       the value for one of the components is negative, or too large.

       Expected ... - specific syntax errors  when  a  particular  type  of  lexical  symbol  was
       expected and not found; the messages are intended to be self-explanatory.

       Internal botch - implementation problem for the parser ...

       Duplicate  name  ``abc'' in subtree for ``'' - for each non-leaf node, the names of
       all immediate descendents must be unique.

       No name space entry for ``root'' - the special non-leaf node with a pathname  of  ``root''
       defines the root of the PMNS, and must appear somewhere in the PMNS specification.

       Multiple  name  space  entries  for  ``root''  - more than one ``root'' node does not make

       Disconnected subtree (``'') in name space - the pathname for this non-leaf node
       does  not correspond to any pathname in the PMNS, hence this non-leaf node is ``orphaned''
       in the PMNS.

       Cannot find definition for non-terminal node ``xyz'' in name space - a  non-terminal  node
       is named as part of its parent's specification, but is never defined.

       Duplicate  metric  id (xxx) in name space for metrics ``abc'' and ``xyz'' - each PMID must
       be unique across the PMNS.
