For example, the root of the default PMNS is a file named +.B root +and the compiled version of the entire namespace is +.BR root.bin . +.PP +The options are; +.TP 5 +.B \-d +By default the PMNS to be compiled is expected to contain at most one +name for each unique Performance Metric Id (PMID). The +.B \-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. +.TP +.B \-f +Force overwriting of an existing +.I outfile +if it already exists. +.TP +.B \-n +Normally +.B pmnscomp +operates on the default PMNS, however if the +.B \-n +option is specified an alternative namespace is loaded +from the file +.IR namespace. +.TP +.B \-v +By default, +.B pmnscomp +writes a version +.B 2 +compiled namespace. +If +.I version +is +.B 1 +then +.B pmnscomp +will write a version +.B 1 +namespace which is similar to version +.BR 2 , +without the extra integrity afforded by checksums. +Note that PCP version 2.0 or later can handle both versions +.B 1 +and +.B 2 +of the binary PMNS format. +.PP +The default input PMNS is found in the file +.I $PCP_VAR_DIR/pmns/root +unless the environment variable +.B PMNS_DEFAULT +is set, in which case the value is assumed to be the pathname +to the file containing the default input PMNS. +.SH CAVEAT +Once the writing of the new +.I outfile +has begun, the signals SIGINT, SIGHUP and SIGTERM will be ignored +to protect the integrity of the new file. +.SH FILES +.PD 0 +.TP 10 +.I $PCP_VAR_DIR/pmns/* +default PMNS specification files +.TP +.I $PCP_VAR_DIR/pmns/root.bin +compiled version of the default PMNS, when the environment variable +.B PMNS_DEFAULT +is unset +.TP +.I $PCP_VAR_DIR/pmns/stdpmid +some standard macros for PMID generation +.PD +.SH "PCP ENVIRONMENT" +Environment variables with the prefix +.B PCP_ +are used to parameterize the file and directory names +used by PCP. +On each installation, the file +.I /etc/pcp.conf +contains the local values for these variables. +The +.B $PCP_CONF +variable may be used to specify an alternative +configuration file, +as described in +.BR pcp.conf (5). +.SH SEE ALSO +.BR pmnsadd (1), +.BR pmnsdel (1), +.BR pmnsmerge (1), +.BR PMAPI (3), +.BR pmLoadNameSpace (3), +.BR pcp.conf (5), +.BR pcp.env (5) +and +.BR pmns (5). +.SH DIAGNOSTICS +Cannot open ``xyz'' \- the filename for the root of the PMNS that was +passed to +.BR pmLoadNameSpace (3) +is bogus. +.PP +Illegal PMID \- either one of the three PMID components (see +.BR pmns (5)) +is not an integer, or the value for one of the +components is negative, or too large. +.PP +Expected ... \- specific syntax errors when a particular type of +lexical symbol was expected and +not found; the messages are intended to be self-explanatory. +.PP +Internal botch \- implementation problem for the parser ... +.PP +Duplicate name ``abc'' in subtree for ``pqr.xyz'' \- for each non-leaf +node, the names of all immediate descendents must be unique. +.PP +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. +.PP +Multiple name space entries for ``root'' \- more than one ``root'' node +does not make sense! +.PP +Disconnected subtree (``abc.xyz.def'') 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. +.PP +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. +.PP +Duplicate metric id (xxx) in name space for metrics ``abc'' and ``xyz'' +\- each PMID must be unique across the PMNS. |
