NAME

       pmnsadd - add new names to the Performance Co-Pilot PMNS

SYNOPSIS

       $PCP_BINADM_DIR/pmnsadd [-?]  [-n namespace] file

DESCRIPTION

       pmnsmerge(1)  performs  the  same  function as pmnsadd and is faster, more robust and more
       flexible.  It is therefore recommended that pmnsmerge(1) be used instead.

       pmnsadd adds subtree(s) of new names into a Performance Metrics Name Space (PMNS), as used
       by the components of the Performance Co-Pilot (PCP).

       Normally pmnsadd operates on the default Performance Metrics Name Space (PMNS), however if
       the -n option is specified an alternative namespace is used from the file namespace.

       The default 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 PMNS.

       The new names are specified in the file, arguments and conform  to  the  syntax  for  PMNS
       specifications,  see  PMNS(5).   There is one PMNS subtree in each file, and the base PMNS
       pathname to the inserted subtree is identified by the first group named in each file, e.g.
       if the specifications begin

                 myagent.foo.stuff {
                     mumble     123:45:1
                     fumble     123:45:2
                 }

       then  the  new  names  will  be added into the PMNS at the non-leaf position identified by
       myagent.foo.stuff, and following all other names with the prefix myagent.foo.

       The new names must be contained within a single subtree of  the  namespace.   If  disjoint
       subtrees  need to be added, these must be packaged into separate files and pmnsadd used on
       each, one at a time.

       All of the files defining the PMNS must be located within the directory that contains  the
       root of the PMNS, this would typically be $PCP_VAR_DIR/pmns for the default PMNS, and this
       would typically imply running pmnsadd as root.

       As a special case, if file contains a line that begins root { then it is assumed to  be  a
       complete  PMNS that needs to be merged, so none of the subtree extraction and rewriting is
       performed and file is handed directly to pmnsmerge(1).

       Provided some initial integrity checks are satisfied, pmnsadd will update the  PMNS  using
       pmnsmerge(1) - if this fails for any reason, the original namespace remains unchanged.

OPTIONS

       The available command line options are:

       -n pmnsfile
            Load an alternative Performance Metrics Name Space (PMNS(5)) from the file pmnsfile.

       -?   Display usage message and exit.

CAVEATS

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

FILES

       $PCP_VAR_DIR/pmns/root
            the default PMNS, when the environment variable PMNS_DEFAULT is unset

PCP ENVIRONMENT

       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(5).
