pmafm: Performance Co-Pilot archive folio manager
NAMEpmafm - Performance Co-Pilot archive folio manager
SYNOPSISpmafm folioname [command [arg ...]]
DESCRIPTIONA collection of one or more Performance Co-Pilot (PCP) archive logs may be combined with a control file to produce a PCP archive folio. Archive folios are created using either mkaf(1) or the interactive ``record mode'' services of PCP clients like pmchart(1).
pmafm provides a number of services that may be used to process folios. In particular, it provides support for execution of PCP tools using one or more of the component archive logs within an archive folio.
The target folio is identified by the folio control file folioname. The syntax for a folio control file is described in mkaf(1).
If present, the command and arguments following folioname are interpreted and executed as a single command, otherwise commands are read from standard input.
The following commands are supported.
- Subsequent commands apply to all archives in the folio.
- archives N[,...]
- Archives within a folio are numbered 1, 2, etc. Subsequent commands are restricted to apply only to the designated archives.
- archives name[,...]
- Archives within a folio have unique names. Subsequent commands are restricted to apply only to the designated archives.
- Validate the presence and format of each file in the folio and the component archives.
A brief reminder of the command syntax. ? is a synonym for help.
Subsequent commands apply to all archives in the folio.
- hosts hostname[,...]
- Subsequent commands are restricted to apply only to those archives that match the designated hostnames.
- list [verbose]
- Display the contents of the folio. By default the control header and the ordinal number, hostname and archive base name for each archive in the folio. The verbose option causes pmafm to dump the label record from each archive using pmdumplog -l.
- The first named archive in the folio is assumed to be associated with the default host for any tool that tries to replay multiple archives from the folio.
Echo on standard output the sh(1) commands required to remove all of the physical files associated with this archive folio.
- repeat tool [arg ...]
Execute the known PCP
once per selected archive. For example, the command
repeat pmval -t60 kernel.all.load
would run pmval(1) once per archive, with an appropriate -a argument.
Some archive folios are created by tools (e.g. pmchart(1)) that provide sufficient information to allow all of the information in all of the archives of a folio to be replayed.
- [run] tool [arg ...]
- Execute the known PCP tool on the selected archives. Some PCP tools are able to process multiple concurrent archives, and in this case the tool is run once with the list of all selected archives passed via a -a argument. Otherwise, this command is synonymous with repeat.
- Display those archives that would be selected for processing with a repeat, replay or run command.
The restrictions via any hosts and archives commands are conjuncted. These restrictions serve to limit the specific archives processed in the subsequent repeat, replay, run and selections commands. By default, all archives are selected.
- control files that define the behavior of each PCP tool known to pmafm. This information may be customized or extended, see $PCP_VAR_DIR/config/pmafm/pcp for documentation of the syntax and semantics of these files.
- User customization of the control files. All files in this directory are treated in the same manner as control files in the $PCP_VAR_DIR/config/pmafm directory.
PCP ENVIRONMENTEnvironment 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).
DIAGNOSTICSMany, but all are intended to be easily understood.
