6.7.7 Viewing VLAN Outage Statistics
The VLAN Outage Monitor provides long-term outage statistics on individual VLANs, which allows you to determine how
your VLANs are performing over time. The VLAN Outage Monitor uses the Link Down trap to determine when an outage
has occurred and the Link Up trap to determine when the outage is cleared. The statistics recorded by the VLAN Outage
Monitor are stored in the NMS database and include:
• Network VLAN name – Name of the monitored Network VLAN
• Availability - The availability of the VLAN expressed as a value from 0 to 1 (0 percent availability to 100 percent
availability)
• Outage Time – Approximate total outage time in days, hours, minutes, seconds, and milliseconds
• MTTR - Approximate mean time to repair in hours calculated as Total Down Time / Number of Failures
• MTBF - Approximate mean time between failures in hours calculated as Total Up Time / Number of Failures
• Number of Failures – Number of failures recorded
• Start Monitor Time – This is the time when the Network VLAN was first created or the last time when the monitoring
was reset.
• Duration – The approximate elapsed time in hours between the Start Monitor Time and Current Monitor Time
The following figure demonstrates a typical monitoring timeline.
