отладчик для PMDA Performance Co-Pilot (debugger for Performance Co-Pilot PMDAs)
Предостережение (Caveat)
A value cannot be stored into metrics of type PM_TYPE_AGGREGATE
or PM_TYPE_EVENT
.
dbpmda
uses fork(2) and exec
(2) to attach to daemon PMDAs.
dbpmda
makes no attempt to detect the termination of the daemon
PMDA process, so it is possible for a PMDA to exit unexpectedly
without any notification. However, any further communication
attempts with the PMDA will result in errors which will indicate
that the PMDA is no longer responding.
