Описание (Description)
pmlogger_daily_report
and the associated systemd(1) services
write daily performance summary reports, much like those produced
by sadc
(1) and the sa2(8) utility.
All of the command line arguments are optional and intended to be
self explanatory. The service is not enabled by default. If the
service is enabled and no arguments are specified,
pmlogger_daily_report
will be run by systemd
at 2am each morning
and write a performance summary report named sar
XX (where XX is
yesterdays day-of-the-month, wrapping to the previous month if
today is the 1st). The outputfile may be changed with the -f
option. The report will be written to the $PCP_LOG_DIR/sa
directory by default, but this may be changed with the -o
option
to a different directory.
Note that there are suffciently flexible command line options for
pmlogger_daily_report
to be used to read any archivefile
and
write the report to any output directory.
If the -a
option is not given, the default input archivefile is
$PCP_ARCHIVE_DIR/HOSTNAME/YYYYMMDD, where HOSTNAME defaults to
the local hostname (unless changed with the -h
option) and
YYYYMMDD is the base name of yesterdays merged archive, as
produced by pmlogger(1) and the pmlogger_daily(1) scripts. If
archivefile is a directory, then pmlogger_daily_report
will use
all PCP archives found in that directory to write the report
(this is known as multi-archive mode, and may be considerably
slower than specifying a single archive as the input).
The reports themselves are created by the pmrep(1) utility using
its default configuration file, see pmrep.conf(5). The pmrep(1)
configuration entries used to write the reports is currently
hardwired into the pmlogger_daily_report
script.
Finally, the input archives must contain sufficient metrics as
needed by pmrep(1) to write the report. On platforms that
support it, the pcp-zeroconf package configures PCP logging as
required for this - hence pmlogger_daily_report
should be used
with the pmlogger(1) configuration that is set up by pcp-
zeroconf
. As the name suggests, pcp-zeroconf
requires no
additional configuration after installation in order to capture
the required archives needed by pmlogger_daily_report
.
Параметры (Options)
The available command line options are:
-a
archive
Specifies an alternate input archive file basename or
directory path.
-A
Use the start and end times of input archive for the report,
as opposed to the default behaviour of 24 hours from
midnight yesterday.
-f
filename
Specifies an alternate output filename. -h
hostname
Specifies an alternateA hostname to use within the default
input archive file path.
-l
file, --logfile
=file
In order to ensure that mail is not unintentionally sent
when this script is run from systemd(1) diagnostics are
always sent to a log file. By default, this file is
$PCP_LOG_DIR/pmlogger/pmlogger_daily_report.log
but this can
be changed using the -l
option. If this log file already
exists when the script starts, it will be renamed with a
.prev suffix (overwriting any log file saved earlier) before
diagnostics are generated to the log file.
-p
If this option is specified then the status of the daily
processing is polled and if the report has not been done in
the last 24 hours then it is done now. The intent is to
have pmlogger_daily_report
called regularly with the -p
option (at 30 mins past the hour, every hour in the default
systemd(1) setup) to ensure daily processing happens as soon
as possible if it was missed at the regularly scheduled time
(2am by default), for example if the system was down or
suspended at that time. With this option,
pmlogger_daily_report
simply exits if the previous day's
processing has already been done.
-t
interval
Specifies the sampling interval used when generating the
report, in the format described in PCPIntro(1). The default
is every 10 minutes.
-V
, --verbose
The output from the execution of the script may be extended
using this option which enables verbose tracing of activity.
By default the script generates no log output unless some
error or warning condition is encountered.
-?
, --help
Display usage message and exit.
Окружение PCP (PCP environment)
Environment variables with the prefix PCP_
are used to
parameterize the file and directory names used by PCP. On each
installation, the file /etc/pcp.conf contains the local values
for these variables. The $PCP_CONF
variable may be used to
specify an alternative configuration file, as described in
pcp.conf(5).
