# perldoc section

=head1 NAME

boinc_projs - Munin plugin to monitor actively running BOINC projects.

=head1 APPLICABLE SYSTEMS

Linux machines running BOINC and munin-node

- or -

Linux servers (running munin-node) used to collect data from other systems 
which are running BOINC, but not running munin-node (e.g. non-Linux systems)

=head1 CONFIGURATION

Following configuration variables are supported:

=over 12

=item B<boinccmd>

command-line control program (default: boinccmd)

=item B<host>

Host to query (default: none)

=item B<port>

GUI RPC port (default: none = use BOINC-default)

=item B<boincdir>

Directory containing appropriate file gui_rpc_auth.cfg (default: none)

=item B<password>

Password for BOINC (default: none) 

=back

=head2 B<Security Consideration:>

Using of variable B<password> poses a security risk. Even if the Munin 
configuration file for this plugin containing BOINC-password is properly 
protected, the password is exposed as environment variable and finally passed 
to boinccmd as a parameter. It is therefore possible for local users of the 
machine running this plugin to eavesdrop the BOINC password. 

Using of variable password is therefore strongly discouraged and is left here 
as a legacy option and for testing purposes.

It should be always possible to use B<boincdir> variable instead - in such case 
the file gui_rpc_auth.cfg is read by boinccmd binary directly. 
If this plugin is used to fetch data from remote system, the gui_rpc_auth.cfg 
can be copied to special directory in a secure way (e.g. via scp) and properly 
protected by file permissions.

=head1 INTERPRETATION

This plugin shows the number of currently running BOINC tasks on the machine. 
If machine is attached to several BOINC projects, data for all these projects 
are displayed.

=head1 EXAMPLES

=head2 Local BOINC Example

BOINC is running on local machine. The BOINC binaries are installed in 
F</opt/boinc/custom-6.10.1/>, the BOINC is running in directory
F</usr/local/boinc/> under username boinc, group boinc and the password is used 
to protect access to BOINC:

  [boinc_*]
  group boinc
  env.boinccmd /opt/boinc/custom-6.10.1/boinccmd
  env.boincdir /usr/local/boinc

=head2 Remote BOINC Example

BOINC is running on 2 remote machines C<foo> and C<bar>. 
On the local machine the binary of command-line interface is installed in 
directory F</usr/local/bin/>.
The BOINC password used on the remote machine C<foo> is stored in file 
F</etc/munin/boinc/foo/gui_rpc_auth.cfg>.
The BOINC password used on the remote machine C<bar> is stored in file 
F</etc/munin/boinc/bar/gui_rpc_auth.cfg>.
These files are owned and readable by root, readable by group munin and not 
readable by others. 
There are 2 symbolic links to this plugin created in the munin plugins 
directory (usually F</etc/munin/plugins/>): F<boincprojs_foo> and 
F<boincprojs_bar>

  [boincprojs_foo]
  group munin
  env.boinccmd /usr/local/bin/boinccmd
  env.host foo
  env.boincdir /etc/munin/boinc/foo

  [boincprojs_bar]
  group munin
  env.boinccmd /usr/local/bin/boinccmd
  env.host bar
  env.boincdir /etc/munin/boinc/bar

This way the plugin can be used by Munin as a virtual node, akin to
SNMP and IPMI plugins.

=head1 BUGS

There is no C<autoconf> capability at the moment. This is due to the fact, that 
BOINC installations may vary over different systems, sometimes using default 
directory from distribution (e.g. F</var/lib/boinc/> in Debian or Ubuntu), but 
often running in user directories or in other separate directories.
Also the user-ID under which BOINC runs often differs. 
Under these circumstances the C<autoconf> would be either lame or too 
complicated.
