создать архивный журнал для показателей производительности (create archive log for performance metrics)
Диагностика (Diagnostic)
The archive logs are sufficiently precious that pmlogger will not
truncate an existing physical file. A message of the form
...: "foo.index" already exists, not over-written
...: File exists
indicates this situation has arisen. You must explicitly remove
the files and launch pmlogger again.
There may be at most one primary pmlogger instance per monitored
host; attempting to bend this rule produces the error:
pmlogger: there is already a primary pmlogger running
Various other messages relating to the creation and/or deletion
of files in $PCP_TMP_DIR/pmlogger suggest a permission problem on
this directory, or some feral files have appeared therein.
