The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
NAME pmtrace – command line performance instrumentation SYNOPSIS pmtrace [-q] [-c value | -e command | -v value] [-h host] [-S state] tag DESCRIPTION pmtrace provides a simple command line interface to the trace Performance Metrics Domain Agent (PMDA) and the associated pcp_trace library. The default pmtrace behavior is to provide point trace data to…
NAME pmtime – time control server for Performance Co-Pilot SYNOPSIS pmtime [-p port] DESCRIPTION pmtime is a graphical user interface for performance monitoring applications using the PCP infrastructure and requiring interactive time control. pmtime is not normally invoked directly by users. Rather, it is more typical for it to be started by client applications (e.g….
NAME pmstore – modify performance metric values SYNOPSIS pmstore [-Lf] [-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…
NAME pmsocks – shell wrapper for performance monitoring across firewalls SYNOPSIS pmsocks path [args …] DESCRIPTION pmsocks allows Performance Co-Pilot (PCP) clients running on hosts located on the internal side of a TCP/IP firewall to monitor remote hosts on the other side of the firewall. This assumes the firewall has been configured with a compliant…
NAME pmsnap – generate performance summary snapshot images SYNOPSIS $PCP_BINADM_DIR/pmsnap [-NV] [-C dir] [-c configs] [-n names] [-o dir] [-t type] DESCRIPTION pmsnap is a shell script that is normally run periodically from crontab(1) to generate graphic images of pmchart(1) performance charts. These images can be in any of the supported pmchart formats, including png,…
NAME pmsignal – send a signal to one or more processes SYNOPSIS $PCP_BINADM_DIR/pmsignal [-alnp] [-s signal] [PID …|name …] DESCRIPTION pmsignal provides a cross-platform event signalling mechanism for use with tools from the Performance Co-Pilot toolkit. It can be used to send a named signal (only HUP, USR1, TERM, and KILL are accepted) to one…
NAME pmrep – performance metrics reporter SYNOPSIS pmrep [-CdGHLpruUVxz?] [-a archive] [-A align] [-b space-scale] [-c config] [-e derived] [-E lines] [-f format] [-F outfile] [-h host] [-K spec] [-l delimiter] [-o output] [-O origin] [-P precision] [-q count-scale] [-s samples] [-S starttime] [-t interval] [-T endtime] [-w width] [-y time-scale] [-Z timezone] metricspec […]…
NAME pmpython – run a python script using a preferred python variant SYNOPSIS pmpython [python-args-and-script] DESCRIPTION pmpython provides a way to run python scripts using a customisable python interpreter, rather than embedding the name of a particular version of python into each script. This can be useful as it allows version-independent python code to be…
NAME pmproxy – proxy for performance metrics collector daemon SYNOPSIS pmproxy [-Af] [-C dirname] [-i ipaddress] [-l logfile] [-L bytes] [-M certname] [-p port[,port …] [-P passfile] [-U username] [-x file] DESCRIPTION pmproxy acts as a protocol proxy for pmcd(1), allowing Performance Co-Pilot (PCP) monitoring clients to connect to one or more pmcd(1) instances via…
NAME pmprobe – lightweight probe for performance metrics SYNOPSIS pmprobe [-fIiLVvz] [-a archive] [-h hostname] [-K spec] [-n pmnsfile] [-O time] [-Z timezone] [metricname …] DESCRIPTION pmprobe determines the availability of performance metrics exported through the facilities of the Performance Co-Pilot (PCP). The metrics of interest are named in the metricname arguments. If metricname is…
NAME pmpost – append messages to the Performance Co-Pilot notice board SYNOPSIS $PCP_BINADM_DIR/pmpost message DESCRIPTION pmpost will append the text message to the end of the Performance Co-Pilot (PCP) notice board file ($PCP_LOG_DIR/NOTICES) in an atomic manner that guards against corruption of the notice board file by concurrent invocations of pmpost. The PCP notice board…
NAME pmpause, pmsleep – portable subsecond-capable sleep SYNOPSIS $PCP_BINADM_DIR/pmpause $PCP_BINADM_DIR/pmsleep interval DESCRIPTION pmpause sleeps indefinitely, until interrupted by SIGKILL. pmsleep sleeps for the specified interval. The interval argument follows the syntax described in PCPIntro(1) for -t, and in the simplest form may be an unsigned integer or floating point constant (the implied units in this…
NAME pmpath – show full path to a perl module SYNOPSIS pmpath module … DESCRIPTION For each module name given as an argument, produces its full path on the standard output, one per line. EXAMPLES $ pmpath CGI /usr/local/devperl/lib/5.00554/CGI.pm $ filsperl -S pmpath IO::Socket CGI::Carp /usr/local/filsperl/lib/5.00554/i686-linux-thread/IO/Socket.pm /usr/local/filsperl/lib/5.00554/CGI/Carp.pm $ oldperl -S pmpath CGI CGI::Imagemap /usr/lib/perl5/CGI.pm /usr/lib/perl5/site_perl/CGI/Imagemap.pm…
NAME pmount – mount arbitrary hotpluggable devices as normal user SYNOPSIS pmount [ options ] device pmount [ options ] device label pmount –lock [ options ] device pid pmount –unlock [ options ] device pid pmount DESCRIPTION pmount ("policy mount") is a wrapper around the standard mount program which permits normal users to mount…
NAME pmnsmerge – merge multiple versions of a Performance Co-Pilot PMNS SYNOPSIS $PCP_BINADM_DIR/pmnsmerge [-adfxv] infile […] outfile DESCRIPTION pmnsmerge merges multiple instances of a Performance Metrics Name Space (PMNS), as used by the components of the Performance Co-Pilot (PCP). Each infile argument names a file that includes the root of a PMNS, of the form…
NAME pmnsdel – delete a subtree of names from the Performance Co-Pilot PMNS SYNOPSIS $PCP_BINADM_DIR/pmnsdel [-n namespace] metricpath [ … ] DESCRIPTION pmnsdel removes subtrees of names from a Performance Metrics Name Space (PMNS), as used by the components of the Performance Co-Pilot (PCP). Normally pmnsdel operates on the default Performance Metrics Name Space (PMNS),…
NAME pmnsadd – add new names to the Performance Co-Pilot PMNS SYNOPSIS $PCP_BINADM_DIR/pmnsadd [-n namespace] file DESCRIPTION pmnsmerge(1) performs the same function as pmnsadd and is faster, more robust and more flexible. It is therefore recommended that pmnsmerge(1) be used instead. pmnsadd adds subtree(s) of new names into a Performance Metrics Name Space (PMNS), as…
NAME pmnewlog – stop and restart archive logging for PCP performance metrics SYNOPSIS $PCP_BINADM_DIR/pmnewlog [-a accessfile] [-C saveconfig] [-c configfile] [-N] [-n pmnsfile] [-P] [-p pid] [-s] [-V] [other pmlogger options] archive DESCRIPTION pmnewlog may be used to stop and restart a running instance of pmlogger(1).
