# 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<snmp_foo_boincprojs> and
F<snmp_bar_boincprojs>
[snmp_foo_boinc*]
group munin
env.boinccmd /usr/local/bin/boinccmd
env.host foo
env.boincdir /etc/munin/boinc/foo
[snmp_bar_boinc*]
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 the same way as the Munin plugins
utilizng SNMP (although this plugin itself does not use SNMP).
=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.
