NAME
pmGetPMNSLocation - determine the location of the currently used
PMNS
C SYNOPSIS
#include <pcp/pmapi.h>
int pmGetPMNSLocation(void);
cc ... -lpcp
DESCRIPTION
If an application needs to know where the Performance Metrics
Name Space (PMNS) is coming from then pmGetPMNSLocation will
return whether it is from an archive, PMNS_ARCHIVE, or from a
local PMNS file, PMNS_LOCAL, or from a remote pmcd, PMNS_REMOTE.
This information may be useful in determining an appropriate
error message depending on the PMNS' location.
DIAGNOSTICS
PM_ERR_NOPMNS
If is not possible to determine where the location of the
PMNS is. This could be due to problems with the current
context or being unable to load a local PMNS.
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). Values for these variables may be obtained
programmatically using the pmGetConfig(3) function.
