 Plugins for nagios compatible monitoring systems like Naemon and Icinga. It
 contains the following plugins:
 .
  check_apt, check_by_ssh, check_clamd, check_cluster,
  check_dhcp, check_disk, check_dummy, check_file_age,
  check_ftp, check_host, check_http, check_icmp,
  check_ide_smart, check_imap, check_ircd, check_jabber,

  check_nagios, check_nntp, check_nntps, check_nt,
  check_ntp, check_ntp_peer, check_ntp_time, check_nwstat,
  check_overcr, check_ping, check_pop, check_procs,
  check_real, check_rta_multi, check_sensors, check_simap,
  check_smtp, check_spop, check_ssh, check_ssmtp,
  check_swap, check_tcp, check_time, check_udp,
  check_ups, check_users
 .
 This package provides a basic set of plugins with minimal external
 dependencies. It is not likely to be useful by itself unless you are
 using a remote "satellite" system (using nagios-nrpe-server, check_by_ssh or
 nsca, for example).
