NAME

       pmsearch - help text and names search for metrics, instances and instance domains

SYNOPSIS

       pmsearch  [-CdinqsStTV?]  [-c config] [-h host] [-p port] [-N number] [-O offset] [query |
       indom]

DESCRIPTION

       pmsearch performs full text search queries to find metrics using names and help text  from
       metrics, instance domains and instances.

       It  makes  use  of  capabilties  of the Performance Co-Pilot (PCP) pmproxy(1) service, the
       Redis distributed data store, and the RediSearch module.

       Note that in order to use these services, it is mandatory that  pmproxy  is  communicating
       with  a  redis-server(1)  that has the redisearch.so module loaded.  When configured to do
       so, pmproxy will then automatically index PCP metric names,  instance  names,  metric  and
       instance  domain  help text into the RediSearch store, from PCP archives that it discovers
       locally.  Refer to pmlogger(1) and pmlogger_daily(1) for further details.

       By default pmsearch communicates with a local  redis-server(1),  however  the  -h  and  -p
       options can be used to specify an alternate Redis instance.  If this instance is a node of
       a Redis cluster,  all  other  instances  in  the  cluster  will  be  discovered  and  used
       automatically.

OPTIONS

       -c config, --config=config
            Specify the config file to use.

       -C, --no-colour
            No highlighting in results text.

       -d, --docid
            Report  document  ID  of each search result.  Documents are identified using a unique
            SHA-1 hash which is always displayed in a 40-hexdigit human readable form.

       -h host, --host=host
            Connect to the Redis server at host, rather than the one the localhost.

       -i, --info
            Report search engine internal metrics.

       -n, --indom
            Perform an instance domain related entities search

       -N N, --number=N
            Return N, search results at most.

       -O N, --offset=N
            Paginated results from given offset.

       -p port, --port=port
            Connect to the Redis server at port, rather than the default 6379.

       -q, --query
            Perform a general text search (default).

       -s, --suggest
            Peform a name suggestion search

       -S, --score
            Report score (rank) of each result.

       -T, --total
            Report total number of of search results.

       -t, --times
            Report elapsed search execution time.

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

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

EXAMPLES

         $ pmsearch kernel idle
         Type: metric
         Name: kernel.all.cpu.idle
         One line: total idle CPU time from /proc/stat for all CPUs

         Type: metric
         Name: kernel.all.idletime
         One line: time the current kernel has been idle since boot

         Type: metric
         Name: kernel.percpu.cpu.idle
         InDom: 60.0
         One line: percpu idle CPU time metric from /proc/stat

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).
