=head1 NAME
sar2pcp - Import sar data and create a PCP archive
=head1 SYNOPSIS
B<sar2pcp> I<infile> I<outfile>
=head1 DESCRIPTION
B<sar2pcp> is intended to read a binary System Activity Reporting
(sar) data file
as created by B<sadc>(1) (I<infile>) and translate this into a Performance
Co-Pilot (PCP) archive with the basename I<outfile>.
However, if I<infile> has the suffix ".xml", then it will be considered
already in XML format and B<sar2pcp> will operate directly on it.
The resultant PCP achive may be used with all the PCP client tools
to graph subsets of the data using B<pmchart>(1),
perform data reduction and reporting, filter with
the PCP inference engine B<pmie>(1), etc.
A series of physical files will be created with the prefix I<outfile>.
These are I<outfile>B<.0> (the performance data),
I<outfile>B<.meta> (the metadata that describes the performance data) and
I<outfile>B<.index> (a temporal index to improve efficiency of replay
operations for the archive). If any of these files exists already,
then B<sar2pcp> will B<not> overwrite them and will exit with an error
message of the form
__pmLogNewFile: "blah.0" already exists, not over-written
B<sar2pcp> is a Perl script that uses the PCP::LogImport Perl wrapper
around the PCP I<libpcp_import>
library, and as such could be used as an example to develop new
tools to import other types of performance data and create PCP archives.
A Python wrapper module is also available.
=head1 CAVEATS
When not using the XML input option, B<sar2pcp> requires I<infile> to
have been created by a version of B<sadc>(1) from
L<http://sebastien.godard.pagesperso-orange.fr/>
which includes the B<sadf>(1) utility
to translate I<infile> into an XML stream (any since version 6);
B<sar2pcp> will automatically run B<sadf>(1) and translate the resultant
XML into a PCP archive.
When using binary B<sadc> files
it is important to ensure the installed B<sadf> is compatible with the
version of B<sadc> that originally generated the binary files. Simply
assuming a newer installed version will work is unfortunately far too
optimistic, and nor should one assume that binary data from different
platforms (e.g. different endianness) will work - these issues are due
to limitations in B<sadc> and B<sadf>, and not in B<sar2pcp> itself.
Fortunately, the B<sadf> message indicating that an incompatibility has
been detected is consistent across versions, and is always prefixed
Invalid system activity file
Using an XML I<infile> has the advantage that the installed version
of B<sadf> is completely bypassed. B<sar2pcp> undertakes to transform
any valid XML produced by any of the different variations of B<sadf>
into a valid PCP archive. Any version of PCP will be able to interpret
the archive files produced by any version of B<sar2pcp>, and you are
also free to move the binary PCP archive between different platforms,
different hardware, even different operating systems - it Just Works (TM).
