pcp2graphite - pcp-to-graphite metrics exporter
pcp2graphite [-h hostspec] [-a archive] [-L] [-O origin] [-T finish]
[-s samples] [-t delta] [-g graphitehost] [-p pickleport] [-P
textport] [-r pickleprotocol] [-u units] [-m prefix] metricname ...
pcp2graphite is a PCP metric exporter. It relays hierarchies of the
pmns(5) to a designated Graphite (Carbon/Whisper) database by
periodically polling, then copying/converting relevant numerical
metrics across the Graphite "text" or "pickled" TCP protocols.
Metric values are optionally scaled to a given unit/scale, but are
not rate-converted. Metric names may be prefixed and are somewhat
canonicalized to fit the Graphite namespace rules.
The data transfer will continue on a best-effort basis until the
program is interrupted. Temporary errors are ignored. Multiple
copies of this program may be run in parallel, to populate different
Graphite databases or subtrees, with different scaling or sampling
intervals.
The pmmgr(1) daemon can be used to ensure one or more pcp2grapite
instances start at system boot time.
-h hostspec
Extract metrics from the specified pmcd(1) daemon, using a
host specification as described on PCPIntro(1). The default
is local:.
-a archive
Extract metrics from the given set of archives, 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.
-L Extract metrics from the local context PCP PMDAs.
-t delta
Specify the polling interval in seconds. If live, polling is
aligned to natural multiples of this interval. The default is
60 seconds.
-O origin
Set the time origin for archive scanning. The default is the
start of the set of archives.
-T finish
Set the time finish for archive scanning. The default is the
end of the set of archives.
-s samples
Set the maximum number of samples to relay. The default is
unlimited.
-g graphitehost
Specify the graphite carbon-cache server where the relayed
data is to be relayed. The default is localhost.
-p pickleport
Select the more efficient "pickled" encoding for carbon-cache
communication, and use the given TCP port. This is the
default, using port 2004.
-P textport
Alternately, select the less efficient "text" encoding for
carbon-cache communication, and use the given TCP port. This
protocol is not default, because it requires a separate TCP
connection for each metric. The typical port is 2003.
-r pickleprotocol
Select the protocol for the "pickled" encoding. The possible
values are:
· 0 - ASCII protocol (the slowest),
· 1 - old binary protocol - pre Python 2.3,
· 2 - new binary protocol introduced in Python 2.3.
The default is 0.
-u units
Rescale the metrics to the given UNITS string, as parsed by
the pmParseUnitsStr(3) function. This must be dimensionally
consistent with the underlying PCP metric. The default is to
perform no scaling.
-m prefix
Use the given string as a prefix for all PMNS metrics relayed
to Graphite. The default is pcp. (note the period at the
end).
metricname
Relay all numeric metrics nested at or below the given name in
the PMNS. This option may be repeated. This is a compulsory
option, having no default.
