This is the command pmstore that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
pmstore - modify performance metric values
SYNOPSIS
pmstore [-L] [-h host] [-i instances] [-K spec] [-n pmnsfile] metricname value
DESCRIPTION
Under certain circumstances, it is useful to be able to modify the values of performance
metrics, for example to re-initialize counters or to assign new values to metrics that act
as control variables.
pmstore changes the current values for the nominated instances of a single performance
metric, as identified by metricname and the list of instance identifiers following the -i
argument. instances must be a single argument, with elements of the list separated by
commas and/or white space. By default all instances of metricname will be updated.
Normally pmstore operates on the default Performance Metrics Name Space (PMNS), however if
the -n option is specified an alternative namespace is loaded from the file pmnsfile.
Unless directed to another host by the -h option, pmstore will interact with the
Performance Metric Collector Daemon (PMCD) on the local host.
The -L option causes pmstore to use a local context to store to metrics from PMDAs on the
local host without PMCD. Only some metrics are available in this mode. The -h and -L
options are mutually exclusive.
The interpretation of value is dependent on the syntax used in its specification and the
underlying data type of metricname, as follows.
1. If the metric has an integer type, then value should be an optional leading hyphen,
followed either by decimal digits or ``0x'' and some hexadecimal digits. ``0X'' is
also acceptable in lieu of ``0x''. See strtol(3C) and the related routines.
2. If the metric has a floating point type, then value should be either in the form of an
integer described above, or a fixed point number, or a number in scientific notation.
See strtod(3C).
3. If the metric has a string type, then value is interpreted as a literal string of
ASCII characters.
4. If the metric has any other type (i.e. PM_TYPE_EVENT or PM_TYPE_AGGREGATE) then no
encoding of value from the command line makes sense, and the values of these metrics
cannot be modified with pmstore.
The output reports the old value and the new value for each updated instance of the
requested metric.
When using the -L option to fetch metrics from a local context, the -K option may be used
to control the DSO PMDAs that should be made accessible. The spec argument conforms to
the syntax described in __pmSpecLocalPMDA(3). More than one -K option may be used.
