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).
