# $Id: //eai/perl5/Rstat-Client/2.2/src/distro/README#2 $ This is the README file for Rstat::Client INTRODUCTION Rstat::Client is a Perll library that provides client access to rstatd(8) statistics for UNIX servers. Connections to rstatd servers are Perl objects, so you may collect statistical data from multiple servers from within one Perl script. Using Rstat::Client is as simple as: use Rstat::Client; $clnt = Rstat::Client->new('some.host'); $stats = $clnt->fetch(); printf 'CPU Load @some.host: %.2f %.2f %.2f\n', @{$stats->{'avenrun'}}; PREREQUISITES Starting with version 2.0, Rstat::Client is implemented in pure Perl and has no specific prerequisites. INSTALLATION Unpack the distribution archive and chdir into Rstat-Client-xxx. Then type the following commands: perl Makefile.PL make make test make install Make sure rstatd is running on localhost or 'make test' will fail.
