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 parameter‐
ize the file and directory names used by PCP. On each installa‐
tion, the file /etc/pcp.conf contains the local values for these
variables. The $PCP_CONF variable may be used to specify an al‐
ternative 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).
