PMSEARCH(1)              General Commands Manual             PMSEARCH(1)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

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

       It makes use of capabilities 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         top

       -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
            Perform 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         top

         $ 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         top

       Environment variables with the prefix PCP_ are used to parameter‐
       ize the file and directory names used by PCP.  On each installa‐
       tion, the file /etc/pcp.conf contains the local values for these
       variables.  The $PCP_CONF variable may be used to specify an al‐
       ternative configuration file, as described in pcp.conf(5).

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