MTBF and MTRS by Host


This widget provides information on the reliability (MTBF) and maintenability (MTRS) of your hosts as well as the level of your team’s efficiency when managing downtime (MTTA). Data is shown as a top N aggregate statistic. Additional information such as current status, availability, number of events or last state change are also provided to help in decision-making.

  • MTBF (mean time between failures) represents the average duration between two DOWN states. The longer the duration, the more reliable the host.

  • MTRS (mean time to restore service) is the average duration between two failures. Hosts with good maintainability have a short MTRS.

  • MTTA (mean time to acknowledge) is the average duration for acknowledging DOWN states. The average is calculated only on acknowledged events.
