pmnsadd
PMNSADD(1) General Commands Manual PMNSADD(1)
NAME
pmnsadd - add new names to the Performance Co-Pilot PMNS
SYNOPSIS
$PCP_BINADM_DIR/pmnsadd [-d] [-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 pmns-
merge(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 Namespace (PMNS), however if the -n option is specified an alternative names-
pace 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 sub-
tree 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.
The -d option allows the resultant PMNS to optionally contain duplicate PMIDs with different names in the PMNS. By default this condition
is considered an error.
CAVEAT
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 then 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 configura-
tion file, as described in pcp.conf(5).
