DESCRIPTION

       pcp2elasticsearch is  a  customizable  performance  metrics  exporter  tool  from  PCP  to
       Elasticsearch.   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.

       pcp2elasticsearch  is  a close relative of pmrep(1).  Refer to pmrep(1) for the metricspec
       description accepted on pcp2elasticsearch command line.  See pmrep.conf(5) for description
       of   the   pcp2elasticsearch.conf   configuration   file   syntax.   This  page  describes
       pcp2elasticsearch specific options and configuration file differences with  pmrep.conf(5).
       pmrep(1)   also   lists   some   usage   examples   of  which  most  are  applicable  with
       pcp2elasticsearch as well.

       Only the command line options listed on this page are supported, other  options  available
       for 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

       pcp2elasticsearch uses a configuration file with 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,
       include_labels, precision, precision_force, count_scale,  count_scale_force,  space_scale,
       space_scale_force,  time_scale,  time_scale_force.  The rest of the pmrep.conf options are
       recognized but ignored for compatibility.

   pcp2elasticsearch specific options
       es_server (string)
           Specify the destination Elasticsearch server metric URL.  Corresponding  command  line
           option is -g.  Defaults to http://localhost:9200/.

       es_auth (string)
           Specify the user name to use with Elasticsearch requests.  Defaults to none.

       es_password (string)
           Specify the pass word to use with Elasticsearch requests.  Defaults to none.

       es_index (string)
           Specify  the  Elasticsearch index for metric names.  Corresponding command line option
           is -x.  Defaults to pcp.

       es_hostid (string)
           Specify the Elasticsearch host-id for measurements.  Corresponding command line option
           is -X.  Defaults to the metrics source host.

       es_search_type (string)
           Specify  the  Elasticsearch  search type for measurements.  Corresponding command line
           option is -p.  Defaults to pcp-metric.

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 pcp2elasticsearch.   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 occurs).

       -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 or directory to use.  In case config is a directory all files
            in  it  ending  .conf  will  be  included.   The  default  is  the  first  found  of:
            ./pcp2elasticsearch.conf,                              $HOME/.pcp2elasticsearch.conf,
            $HOME/pcp/pcp2elasticsearch.conf,  and  $PCP_SYSCONF_DIR/pcp2elasticsearch.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 PCP derived metrics configuration file,
            otherwise it will be interpreted as  comma-  or  semicolon-separated  derived  metric
            expressions.   For  complete  description  of derived metrics and PCP derived metrics
            configuration   files   see    pmLoadDerivedConfig(3)    and    pmRegisterDerived(3).
            Alternatively,  using  pmrep.conf(5)  configuration  syntax  allows  defining derived
            metrics as part of metricsets.

       -g URL, --es-host=URL
            Destination Elasticsearch server metric URL.

       -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
            Retrieve  and  report only the specified metric instances.  By default all instances,
            present and future, are reported.

            Refer to pmrep(1) for complete description of 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 pcp2elasticsearch 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.

       -j, --live-filter
            Perform instance live filtering.  This allows capturing all named instances  even  if
            processes  are  restarted  at some point (unlike without live filtering).  Performing
            live filtering over a huge number 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.

       -m, --include-labels
            Include PCP metric labels in the output.

       -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 type, --es-search-type=type
            Elasticsearch search type for measurements.

       -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  samples argument defines the number of samples to be retrieved and reported.  If
            samples is 0 or -s  is  not  specified,  pcp2elasticsearch  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 pcp2elasticsearch 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
            pcp2elasticsearch will run.

       -v, --omit-flat
            Report  only  set-valued metrics with instances (e.g. disk.dev.read) and omit single-
            valued ``flat'' metrics without instances (e.g.  kernel.all.sysfork).  See -i and -I.

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

       -x index, --es-index=index
            Elasticsearch index for metric names.

       -X hostid, --es-hostid=hostid
            Elasticsearch hostid for measurements.

       -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.

OUTPUT FORMAT

       First, pcp2elasticsearch sends this type definition to Elasticsearch:

               {
                   "mappings": {
                       "pcp-metric": {
                           "properties": {
                               "@timestamp": {
                                   "type": "date"
                               },
                               "host-id": {
                                   "type": "string"
                               }
                           }
                       }
                   }
               }

       The actual metrics data document is similar to this example:

               {
                   "@host-id": "bozo",
                   "mem": {
                       "util": {
                           "used": 4525820,
                           "free": 3344000
                       }
                   },
                   "@timestamp": 1507637520,
                   "disk": {
                       "partitions": {
                           "@instances": [
                               {
                                   "read": 1121,
                                   "@id": "sda1"
                               },
                               {
                                   "read": 77306,
                                   "@id": "sda2"
                               },
                               {
                                   "read": 131,
                                   "@id": "sda3"
                               }
                           ]
                       }
                   }
               }

FILES

       pcp2elasticsearch.conf
            pcp2elasticsearch configuration file (see -c)

       $PCP_SYSCONF_DIR/pmrep/*.conf
            system provided default pmrep configuration files

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).
