=head1 NAME
multips - Munin plugin to monitor number of processes. Which processes
are configured in client-conf.d
=head1 APPLICABLE SYSTEMS
Any system with a pgrep, /usr/ucb/ps or other UCB compatible ps command.
=head1 CONFIGURATION
There is no default configuration. This is an example:
[multips]
env.names pop3d imapd sslwrap
env.regex_imapd ^[0-9]* imapd:
env.regex_pop3d ^[0-9]* pop3d:
The regex parts are not needed if the name given in "names" can be
used to grep with directly.
=head1 INTERPRETATION
This plugin simply counts the total number of processes matching the
configured regular expressions. The regular expressions are
interpreted by "grep" (and not egrep or perl).
