Jump to navigation Jump to search


In OpenNMS outages are shown only as events on the node detail page. To get a better way visualizing outages for an service on a specific interface a visual component is introduced. The outages are represented in a horizontal bar chart which represents the last 24 hours. Outages and duration are displayed in red. The outages in the bar chart should give a link to the outage causing this outage.
