Nagios or Icinga Web interface based on NDO. It allows you to view almost everything about Nagios or Icinga in a single page: alert, ack, downtime, comment. You can also interact with Nagios or Icinga through ack, downtime, comment, disable, and reset buttons. You can filter on hosts and services states (critical, warning, unknown, ok, outage...). The status popin allows to display graphs, either the ones from Nagios (trends.cgi) or custom ones based on RRD (pnp4nagios, ...).
