экспортер показателей pcp-to-spark (pcp-to-spark metrics exporter)
Описание (Description)
pcp2spark is a customizable performance metrics exporter tool
from PCP to Apache Spark. 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.
pcp2spark acts as a bridge which provides a network socket stream
on a given address/port which an Apache Spark worker task can
connect to and pull the configured PCP metrics from pcp2spark
exporting them using the streaming extensions of the Apache Spark
API.
pcp2spark is a close relative of pmrep(1). Refer to pmrep(1) for
the metricspec description accepted on pcp2spark command line.
See pmrep.conf(5) for description of the pcp2spark.conf
configuration file overall syntax. This page describes pcp2spark
specific options and configuration file differences with
pmrep.conf(5). pmrep(1) also lists some usage examples of which
most are applicable with pcp2spark 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).
