Описание (Description)
As part of the Performance Co-Pilot Log Import API (see
LOGIMPORT(3)), pmiPutMark writes a <mark> record to the current
PCP output archive. This is required when there is a temporal
discontinuity between the current input source and the next input
source, if any, and should be called after the final call to
pmiWrite(3) for the current input. If there is no next input to
be processed or no temporal gap between sources, then the <mark>
record is not required.
The <mark> record is used to signify a temporal gap, so that when
replaying the output PCP archive, interpolation of metric values
should not be performed between the last timestamp in the current
input source to the first timestamp in the next input source,
i.e. across the <mark> record.
Диагностика (Diagnostic)
pmiPutMark returns zero on success else a negative value that can
be turned into an error message by calling pmiErrStr(3).
