DESCRIPTION

       pcp2zabbix is a customizable performance metrics exporter tool from PCP  to  Zabbix.   Any
       available performance metric, live or archived, system and/or application, can be selected
       for exporting using either command line arguments or a configuration file.

       pcp2zabbix is a close relative of pmrep(1).  Please refer to pmrep(1) for  the  metricspec
       description  accepted  on pcp2zabbix command line and pmrep.conf(5) for description of the
       pcp2zabbix.conf configuration file overall syntax, this page describes pcp2zabbix specific
       options  and  configuration file differences with pmrep.conf(5).  pmrep(1) also lists some
       usage examples of which most are applicable with pcp2zabbix as well.

       Only the command line options listed on this page are supported, other options  recognized
       by pmrep(1) are not supported.

       Options  via  environment values (see pmGetOptions(3)) override the corresponding built-in
       default  values  (if  any).   Configuration  file  options  override   the   corresponding
       environment   variables  (if  any).   Command  line  options  override  the  corresponding
       configuration file options (if any).

CONFIGURATION FILE

pcp2zabbix uses a configuration file with overall syntax described in pmrep.conf(5). The
following options are common with pmrep.conf: version, source, speclocal, derived, header,
globals, samples, interval, type, type_prefer, ignore_incompat, names_change, instances,
live_filter, rank, limit_filter, limit_filter_force, invert_filter, predicate, omit_flat,
precision, precision_force, count_scale, count_scale_force, space_scale,
space_scale_force, time_scale, time_scale_force. The output option is recognized but
ignored for pmrep.conf compatibility.

pcp2zabbix specific options
zabbix_server (string)
Hostname or IP address of Zabbix server to send the metrics to. If a host is
monitored by a proxy, proxy hostname or IP address should be used instead.
Corresponding command line option is -g. Default is localhost.

zabbix_port (integer)
Specify port number of server trapper running on the server. Corresponding command
line option is -p. Default is 10051.

zabbix_host (string)
Specify agent hostname as registered in Zabbix frontend. Host IP address and DNS name
will not work. Corresponding command line option is -X. Defaults to the metrics
source host.

zabbix_interval (string)
Indicates the interval to send the metrics to the Zabbix server. This can be longer
than the generic interval to minimize the overhead when communicating with the server
(as each send creates a new connection). Follows the time syntax described in
PCPIntro(1). Corresponding command line option is -E. Defaults to the generic
interval. Zabbix tools send at most 250 metrics at a time. Ignored when reading
metrics from PCP archives, in which case metrics will be sent roughly at 250 metric
batches.

zabbix_prefix (string)
Specify the prefix for metrics sent to the Zabbix server. Corresponding command line
option is -x. Default is .pcp.

zabbix_lld (boolean)
Specify whether to enable Zabbix low-level discovery. Corresponding command line
option is -l. Default is no.

OPTIONS

The available command line options are:

-0 precision, --precision-force=precision
Like -P but this option will override per-metric specifications.

-4 action, --names-change=action
Specify which action to take on receiving a metric names change event during
sampling. These events occur when a PMDA discovers new metrics sometime after
starting up, and informs running client tools like pcp2zabbix. Valid values for
action are update (refresh metrics being sampled), ignore (do nothing - the default
behaviour) and abort (exit the program if such an event happens).

-5, --ignore-unknown
Silently ignore any metric name that cannot be resolved. At least one metric must be
found for the tool to start.

-8 limit, --limit-filter=limit
Limit results to instances with values above/below limit. A positive integer will
include instances with values at or above the limit in reporting. A negative integer
will include instances with values at or below the limit in reporting. A value of
zero performs no limit filtering. This option will not override possible per-metric
specifications. See also -J and -N.

-9 limit, --limit-filter-force=limit
Like -8 but this option will override per-metric specifications.

-a archive, --archive=archive
Performance metric values are retrieved from the set of Performance Co-Pilot (PCP)
archive log files identified by the archive argument, which is a comma-separated list
of names, each of which may be the base name of an archive or the name of a directory
containing one or more archives.

-A align, --align=align
Force the initial sample to be aligned on the boundary of a natural time unit align.
Refer to PCPIntro(1) for a complete description of the syntax for align.

--archive-folio=folio
Read metric source archives from the PCP archive folio created by tools like
pmchart(1) or, less often, manually with mkaf(1).

-b scale, --space-scale=scale
Unit/scale for space (byte) metrics, possible values include bytes, Kbytes, KB,
Mbytes, MB, and so forth. This option will not override possible per-metric
specifications. See also pmParseUnitsStr(3).

-B scale, --space-scale-force=scale
Like -b but this option will override per-metric specifications.

-c config, --config=config
Specify the config file to use. The default is the first found of:
./pcp2zabbix.conf, $HOME/.pcp2zabbix.conf, $HOME/pcp/pcp2zabbix.conf, and
$PCP_SYSCONF_DIR/pcp2zabbix.conf. For details, see the above section and
pmrep.conf(5).

--container=container
Fetch performance metrics from the specified container, either local or remote (see
-h).

-C, --check
Exit before reporting any values, but after parsing the configuration and metrics and
printing possible headers.

--daemonize
Daemonize on startup.

-e derived, --derived=derived
Specify derived performance metrics. If derived starts with a slash (``/'') or with
a dot (``.'') it will be interpreted as a derived metrics configuration file,
otherwise it will be interpreted as comma- or semicolon-separated derived metric
expressions. For details see pmLoadDerivedConfig(3) and pmRegisterDerived(3).

-E interval, --zabbix-interval=interval
Specify the interval to send metrics to the server. See zabbix_interval description
above for details.

-g server, --zabbix-server=server
Zabbix server to send the metrics to.

-G, --no-globals
Do not include global metrics in reporting (see pmrep.conf(5)).

-h host, --host=host
Fetch performance metrics from pmcd(1) on host, rather than from the default
localhost.

-H, --no-header
Do not print any headers.

-i instances, --instances=instances
Report only the listed instances from current instances (if present, see also -j).
By default all instances, present and future, are reported. This is a global option
that is used for all metrics unless a metric-specific instance definition is provided
as part of a metricspec. By default single-valued ``flat'' metrics without multiple
instances are still reported as usual, use -v to change this. Please refer to
pmrep(1) for more details on this option.

-I, --ignore-incompat
Ignore incompatible metrics. By default incompatible metrics (that is, their type is
unsupported or they cannot be scaled as requested) will cause pcp2zabbix to terminate
with an error message. With this option all incompatible metrics are silently
omitted from reporting. This may be especially useful when requesting non-leaf nodes
of the PMNS tree for reporting.

-l, --zabbix-lld
Add low-level discovery (LLD) metrics. This allows PCP metric instance domains to be
sent to Zabbix, so that prototype items/triggers/graphs may be automatically
constructed by Zabbix. For each PCP metric with an instance domain, the key
pcp.discovery[pcp.met.ric] is sent periodically. This symbol should be added to a
discovery rule, and will define the {#PCP.MET.RIC} LLD macro. This macro can in turn
be used to define prototype items/triggers/graphs. The names are adjusted if -x was
given to override the pcp. prefix.

-j, --live-filter
Perform instance live filtering. This allows capturing all filtered instances even
if processes are restarted at some point (unlike without live filtering). Performing
live filtering over a huge amount of instances will add some internal overhead so a
bit of user caution is advised. See also -n.

-J rank, --rank=rank
Limit results to highest/lowest ranked instances of set-valued metrics. A positive
integer will include highest valued instances in reporting. A negative integer will
include lowest valued instances in reporting. A value of zero performs no ranking.
Ranking does not imply sorting, see -6. See also -8.

-K spec, --spec-local=spec
When fetching metrics from a local context (see -L), 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.

-L, --local-PMDA
Use a local context to collect metrics from DSO PMDAs on the local host without PMCD.
See also -K.

-n, --invert-filter
Perform ranking before live filtering. By default instance live filtering (when
requested, see -j) happens before instance ranking (when requested, see -J). With
this option the logic is inverted and ranking happens before live filtering.

-N predicate, --predicate=predicate
Specify a comma-separated list of predicate filter reference metrics. By default
ranking (see -J) happens for each metric individually. With predicates, ranking is
done only for the specified predicate metrics. When reporting, rest of the metrics
sharing the same instance domain (see PCPIntro(1)) as the predicate will include only
the highest/lowest ranking instances of the corresponding predicate. Ranking does
not imply sorting, see -6.

So for example, using proc.memory.rss (resident memory size of process) as the
predicate metric together with proc.io.total_bytes and mem.util.used as metrics to be
reported, only the processes using most/least (as per -J) memory will be included
when reporting total bytes written by processes. Since mem.util.used is a single-
valued metric (thus not sharing the same instance domain as the process-related
metrics), it will be reported as usual.

-O origin, --origin=origin
When reporting archived metrics, start reporting at origin within the time window
(see -S and -T). Refer to PCPIntro(1) for a complete description of the syntax for
origin.

-p port, --zabbix-port=port
Zabbix server port number.

-P precision, --precision=precision
Use precision for numeric non-integer output values. The default is to use 3 decimal
places (when applicable). This option will not override possible per-metric
specifications.

-q scale, --count-scale=scale
Unit/scale for count metrics, possible values include count x 10^-1, count, count x
10, count x 10^2, and so forth from 10^-8 to 10^7. (These values are currently
space-sensitive.) This option will not override possible per-metric specifications.
See also pmParseUnitsStr(3).

-Q scale, --count-scale-force=scale
Like -q but this option will override per-metric specifications.

-r, --raw
Output raw metric values, do not convert cumulative counters to rates. This option
will override possible per-metric specifications.

-R, --raw-prefer
Like -r but this option will not override per-metric specifications.

-s samples, --samples=samples
The argument samples defines the number of samples to be retrieved and reported. If
samples is 0 or -s is not specified, pcp2zabbix will sample and report continuously
(in real time mode) or until the end of the set of PCP archives (in archive mode).
See also -T.

-S starttime, --start=starttime
When reporting archived metrics, the report will be restricted to those records
logged at or after starttime. Refer to PCPIntro(1) for a complete description of the
syntax for starttime.

-t interval, --interval=interval
Set the reporting interval to something other than the default 1 second. The
interval argument follows the syntax described in PCPIntro(1), and in the simplest
form may be an unsigned integer (the implied units in this case are seconds). See
also the -T option.

-T endtime, --finish=endtime
When reporting archived metrics, the report will be restricted to those records
logged before or at endtime. Refer to PCPIntro(1) for a complete description of the
syntax for endtime.

When used to define the runtime before pcp2zabbix will exit, if no samples is given
(see -s) then the number of reported samples depends on interval (see -t). If
samples is given then interval will be adjusted to allow reporting of samples during
runtime. In case all of -T, -s, and -t are given, endtime determines the actual time
pcp2zabbix will run.

-v, --omit-flat
Omit single-valued ``flat'' metrics from reporting, only consider set-valued metrics
(i.e., metrics with multiple values) for reporting. See -i and -I.

-V, --version
Display version number and exit.

-x prefix, --zabbix-prefix=prefix
Metrics prefix for measurements sent to the server.

-X hostname, --zabbix-host=hostname
Specify the agent hostname as registered in Zabbix frontend.

-y scale, --time-scale=scale
Unit/scale for time metrics, possible values include nanosec, ns, microsec, us,
millisec, ms, and so forth up to hour, hr. This option will not override possible
per-metric specifications. See also pmParseUnitsStr(3).

-Y scale, --time-scale-force=scale
Like -y but this option will override per-metric specifications.

-?, --help
Display usage message and exit.

FILES

       pcp2zabbix.conf
            pcp2zabbix configuration file (see -c)

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).

       For environment variables affecting PCP tools, see pmGetOptions(3).
