6 ganglia2pcp - import ganglia data and create a PCP archive

9 ganglia2pcp [-d outdir] [-e end] [-f outfile] [-h hostname] [-s start]
10 [-Z timezone] input_dir
11
13 ganglia2pcp is intended to read a set of ganglia files stored in the
14 rrd format and translate them into a Performance Co-Pilot (PCP) archive
15 with the basename outfile.
16 The intent of this converter is to take all of the rrd files found in
18 the input_dir and generate a single pcp archive file. The mapping of
19 ganglia metrics to pcp metrics is defined internally.
20 The resultant PCP achive may be used with all the PCP client tools to
22 graph subsets of the data using pmchart(1), perform data reduction and
23 reporting, filter with the PCP inference engine pmie(1), etc.
24 A series of physical files will be created with the prefix outfile.
26 These are outfile.0 (the performance data), outfile.meta (the metadata
27 that describes the performance data) and outfile.index (a temporal
28 index to improve efficiency of replay operations for the archive). If
29 any of these files exists already, then sar2pcp will not overwrite them
30 and will exit with an error message of the form
31 __pmLogNewFile: ``blah.0'' already exists, not over-written
33 ganglia2pcp is a Perl script that uses the PCP::LogImport Perl wrapper
35 around the PCP libpcp_import library, and as such could be used as an
36 example to develop new tools to import other types of performance data
37 and create PCP archives. The RRDs Perl wrapper is used to parse the
38 raw rrd format files.

41 The available command line options are:
42 -d outdir
44 The outdir argument specifies a output to write to. The default
45 is the current directory.
46 -e end
48 The end argument specifies a end time in a format understood by
49 str2time. The default start time is current time.
50 -f outfile
52 The outfile argument specifies a output file name. The default
53 name is in the standard pmlogger format based on the start time,
54 e.g., 20150201.00.10.
55 -h hostname
57 The hostname argument specifies a hostname to write to the ar‐
58 chive. The default is taken from the directory name that the rrd
59 files reside in.
60 -s start
62 The start argument specifies a start time in a format understood
63 by str2time. The default start time is 24 prior to current time.
64 -Z timezone
66 The timezone argument sets the source timezone in the PCP archive
67 (the default is to use the local timezone). The timezone must
68 have the format +HHMM (for hours and minutes East of UTC) or -HHMM
69 (for hours and minutes West of UTC) or UTC. Note in particular
70 that neither the zoneinfo (aka Olson) format, e.g. Europe/Paris,
71 nor the Posix TZ format, e.g. EST+5 is allowed. Example: time‐
72 zone=``+1100''.
73
75 Environment variables with the prefix PCP_ are used to parameterize the
76 file and directory names used by PCP. On each installation, the file
77 /etc/pcp.conf contains the local values for these variables. The
78 $PCP_CONF variable may be used to specify an alternative configuration
79 file, as described in pcp.conf(5).
