администрирование файлов журналов архива Performance Co-Pilot (administration of Performance Co-Pilot archive log files)
Описание (Description)
These shell scripts and associated control files may be used to
create a customized regime of administration and management for
Performance Co-Pilot (see PCPIntro(1)) archive log files.
pmlogger_check
may be run at any time of the day and is intended
to check that a desired set of pmlogger(1) processes are running.
If not, it (re-)starts any missing logger processes.
pmlogger_daily
is intended to be run once per day, preferably in
the early morning, as soon after midnight as practicable. Its
task is to aggregate, rotate and perform general housekeeping one
or more sets of PCP archives.
To accommodate the evolution of PMDAs and changes in production
logging environments, pmlogger_daily
is integrated with
pmlogrewrite(1) to allow optional and automatic rewriting of
archives before merging. If there are global rewriting rules to
be applied across all archives mentioned in the control file(s),
then create the directory $PCP_SYSCONF_DIR/pmlogrewrite
and place
any pmlogrewrite(1) rewriting rules in this directory. For
rewriting rules that are specific to only one family of archives,
use the directory name from the control file(s) - i.e. the fourth
field - and create a file, or a directory, or a symbolic link
named pmlogrewrite
within this directory and place the required
rewriting rule(s) in the pmlogrewrite
file or in files within the
pmlogrewrite
subdirectory. pmlogger_daily
will choose rewriting
rules from the archive directory if they exist, else rewriting
rules from $PCP_SYSCONF_DIR/pmlogrewrite
if that directory
exists, else no rewriting is attempted.
As an alternate mechanism, if the file
$PCP_LOG_DIR/pmlogger/.NeedRewrite
exists when pmlogger_daily
starts then this is treated the same as specifying -R
on the
command line and $PCP_LOG_DIR/pmlogger/.NeedRewrite
will be
removed once all the rewriting has been done.
