PMGETPMNSLOCATION(3) Library Functions Manual PMGETPMNSLOCATION(3)
pmGetPMNSLocation - determine the location of the currently used
PMNS
#include <pcp/pmapi.h>
int pmGetPMNSLocation(void);
cc ... -lpcp
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.
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.
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.
PMAPI(3), pmGetConfig(3), pmLoadASCIINameSpace(3),
pmLoadNameSpace(3), pmTrimNameSpace(3), pcp.conf(5), pcp.env(5)
and PMNS(5).
