NAME

       pcp.conf - the Performance Co-Pilot configuration and environment file

SYNOPSIS

       /etc/pcp.conf

DESCRIPTION

       When  using  Performance Co-Pilot (PCP) tools and utilities and when calling PCP library functions, a standard set of environment variables
       are defined in /etc/pcp.conf.  These variables are generally used to specify the location of various PCP pieces in the file system and  may
       be  loaded  into  shell scripts by sourcing the /etc/pcp.env(5) shell script and queried by C/C++ programs using the pmGetConfig(3) library
       function.  If a variable is already defined in the environment, the values in pcp.conf do not override those values,  i.e.  the	values	in
       pcp.conf serve as installation defaults only.

       Both  the  pcp.env  and	pcp.conf  files  are expected to be found in /etc by default.  If required, the pcp.conf file may be relocated and
       PCP_CONF set in the environment to specify the full path to the new location.  The pcp.env file can not be relocated (this is the only hard
       coded path required by PCP).

       The syntax rules for pcp.conf are as follows :

       1.  the general syntax is
						       PCP_VARIABLE_NAME=variable value to end of line

       2.  lines that begin with # and all blank lines are ignored.

       3.  all variables must be prefixed with PCP_.  This is a security issue - variables that do not have this prefix will be silently ignored.

       4.  there  should  be  no  space  between the variable name and the literal = and no space between the = and the variable value (unless the
	   value actually starts with a space).  This is required because the pcp.conf file may be sourced directly by Makefiles as well as inter-
	   preted by the pcp.env script and the pmGetConfig function.

       5.  variable  values  may  contain  spaces  and should not be quoted.  The pcp.env script automatically quotes all variable values from the
	   character immediately following the = through to the end of the line.

       For further details and an explanation of the use of each variable, see the comments in the /etc/pcp.conf file itself.

ENVIRONMENT

       The PCP_CONF environment variable specifies an alternative path to the pcp.conf file.

NAME

       pmnsdel - delete a subtree of names from the Performance Co-Pilot PMNS

SYNOPSIS

       $PCP_BINADM_DIR/pmnsdel [-d] [-n namespace] metricpath [ ... ]

DESCRIPTION

       pmnsdel	removes  subtrees  of  names  from  a Performance Metrics Name Space (PMNS), as used by the components of the Performance Co-Pilot
       (PCP).

       Normally pmnsdel 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 metric names to be deleted are all those for which one of the metricpath arguments is a prefix in the PMNS, see pmns(5).

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

       Provided  some  initial	integrity  checks are satisfied, pmnsdel will update the necessary PMNS files.	Should an error be encountered the
       original namespace is restored.	Note that any PMNS files that are no longer referenced by the modified namespace will not be removed, even
       though their contents are not part of the new namespace.

       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).
