=head1 CONFIGURATION
Since the aim of the C<snmp plugin> is to provide a generic interface to SNMP,
-it's configuration is not trivial and may take some time.
+its configuration is not trivial and may take some time.
Since the C<Net-SNMP> library is used you can use all the environment variables
that are interpreted by that package. See L<snmpcmd(1)> for more details.
B<Step> of generated RRD files depends on this setting it's wise to select a
reasonable value once and never change it.
+=item B<Timeout> I<Seconds>
+
+How long to wait for a response. The C<Net-SNMP> library default is 1 second.
+
+=item B<Retries> I<Integer>
+
+The number of times that a query should be retried after the Timeout expires.
+The C<Net-SNMP> library default is 5.

"Hidden" files and directories are those, whose name begins with a dot.

+Collects information about processes of local system.
-=item B<Process> I<Name>
+By default, with no process matches configured, only general statistics is
+collected: the number of processes in each state and fork rate.
+
+Process matches can be configured by B<Process> and B<ProcessMatch> options.
+These may also be a block in which further options may be specified.
-Select more detailed statistics of processes matching this name. The statistics
-collected for these selected processes are:
+The statistics collected for matched processes are:
- size of the resident segment size (RSS)
- user- and system-time used
- number of processes
- context switches (under Linux)
- minor and major pagefaults.
-Some platforms have a limit on the length of process names. I<Name> must stay
-below this limit.
