PMSORTINSTANCES(3) Library Functions Manual PMSORTINSTANCES(3)NAME
pmSortInstances - sort performance metric values on instance identifier
C SYNOPSIS
#include <pcp/pmapi.h>
void pmSortInstances(pmResult *result);
cc ... -lpcp
DESCRIPTION
The routine pmSortInstances may be used to guarantee that for each performance metric in the result from pmFetch(3), the instances are in
ascending instance identifier sequence.
This is most useful when trying to compute rates from two consecutive pmFetch(3) results.
SEE ALSO PMAPI(3) and pmFetch(3).
DIAGNOSTICS
None.

PMDELPROFILE(3) Library Functions Manual PMDELPROFILE(3)NAME
pmDelProfile - delete instance(s) from the current PMAPI instance profile
C SYNOPSIS
#include <pcp/pmapi.h>
int pmDelProfile(pmInDom indom, int numinst, int *instlist);
cc ... -lpcp
DESCRIPTION
The set of instances for performance metrics returned from a pmFetch(3) call may be filtered or restricted using an instance profile.
There is one instance profile for each context the application creates at the Performance Metrics Application Programming Interface
(PMAPI), and each instance profile may include instances from one or more instance domains (see pmLookupDesc(3)).
pmDelProfile may be used to delete instance specifications from the instance profile of the current PMAPI context.
In the simplest variant, the list of instances identified by the instlist argument for the indom instance domain are removed from the
instance profile. The list of instance identifiers contains numinst values.
The indom value would normally be extracted from a call to pmLookupDesc(3) for a particular performance metric, and the instances in
instlist would typically be determined by calls to pmGetInDom(3) or pmLookupInDom(3).
If indom equals PM_INDOM_NULL or numinst is zero, then all instance domains are selected for deletion. If instlist is NULL, then all
instances in the selected domain(s) are removed from the profile.
To disable all available instances in all domains, use pmDelProfile(PM_INDOM_NULL, 0, NULL). This is the only situation in which indom may
be PM_INDOM_NULL.
SEE ALSO pmAddProfile(3), PMAPI(3), pmFetch(3), pmGetInDom(3), pmLookupDesc(3), pmLookupInDom(3), pmNewContext(3), pmUseContext(3) and pmWhichCon-
text(3).
DIAGNOSTICS
PM_ERR_PROFILESPEC
indom was PM_INDOM_NULL and instlist was not empty
CAVEAT
It is possible to delete non-existent instance domains and non-existent instances from an instance profile. None of the routines that use
the instance profile will ever issue an error if you do this. The cost of checking, when checking is possible, outweighs any benefits.
