PCP-XSOS(1) General Commands Manual PCP-XSOS(1)
pcp-xsos - high-level summary reports for a system
pcp [pcp options] xsos [--all] [-dmnNopx] [-u units]
pcp-xsos gives a summary report of a system using either a PCP
archive or live metric values from that system.
It is designed to be fast and performs a single-sample only,
similar to tools like ps(1). Thus, level of detail in reporting
is traded off in favour of execution speed. pcp-xsos is designed
as an initial performance triage tool that quickly informs an
operator as to avenues of investigation that may prove more
fruitful. At this time the focus is entirely on operating system
metrics, however this is not a requirement and in time it may be
extended to report on any performance domain with associated PCP
metrics.
When invoked via the pcp(1) command, the -h/--host, -a/--archive,
-O/--origin pcp options become indirectly available, see
PCPIntro(1) for their descriptions.
The default report with no command line options presented is the
operating system overview.
The available command line options are:
--all
iteratively report each subsection, one after the other.
-o, --os
display the default report with high level kernel
information, including version, uptime, number of users,
process states and aggregated processor utilisation.
-d, --disks
Report storage information from the archive or live host,
including the total capacity for each block device as well as
available filesystem space for each mounted filesystem.
-m, --memory
Detailed memory report, including percentage of total memory
used for various operating system functions, swap use, and
optionally hugepages and virtual machine balloon information.
-n, --netdev
Statistics for each configured network interface, including
packet and byte transfer rates (since boot), errors, drops,
and so on. Additionally, socket statistics are also reported
with this command line option, for raw, UDP and TCP (IPv4 and
IPv6).
-N, --netstats
Report aggregate network statistics such as various ICMP and
TCP error and timeout counters.
-p, --ps
Inspect running processes in a style similar to ps. These
are grouped and filtered to show the most important processes
in terms of resource use (CPU, memory) as well as processes
in zombie or blocked states.
-u unit, --units=unit
Change the byte display for various reports. Valid values
for unit are "b" (bytes), "k" (kibibytes), "m" (mibibytes),
"g" (gibibytes) or "t" (tebibytes).
-x, --nocolor
Display reports without using colors to highlight various
aspects of each subsystem.
-?, --help
Display usage message and exit.
pcp-xsos is inspired by the xsos utility, aims to be command line
compatible with it where possible and also provide a consistent
output style.
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).
For environment variables affecting PCP tools, see pmGetOptions(3)
which provides pmgetopt(1) functionality used by pcp-xsos.
PCPIntro(1), pcp(1), ps(1), pmgetopt(1), pmGetOptions(3) and
environ(7).
