Interface Availability Summary Report

The Interface Availability Summary Report provides an overview of the availability of network interfaces across monitored devices over a specified time period. This report helps IT teams track interface uptime, downtime, performance, mean time to repair (MTTR), mean time between failures (MTBF), and more. 

How it helps

• Monitoring network reliability: IT teams can measure how stable the router and its interfaces are.
• Pinpointing outage causes: See which interfaces failed, when, and for how long.
• Assessing efficiency of repairs: Gauge how quickly issues are resolved and how often failures occur using the MTTR and MTBF metrics.
• Assisting decision-making: Help teams improve network resilience by addressing recurring issues.

Generate an Interface Availability Summary Report

1. Log in to your Site24x7 account.
2. Navigate to Reports and search for Network Device > Interface Availability Summary Report.
3. Change the listed parameters to view a customized report:
   1. Select the required Monitor from the Monitors drop-down menu.
   2. Select Interfaces in the Resource Type drop-down menu.
   3. Select the required interfaces in the Resources drop-down menu. 
   4. Next, select the Time Period. 
   5. Then select Business Hours.
   6. Select Locations, if available.
4. You can now view the following metrics:

   Metrics	Description
   Availability	Represents the percentage of time the monitor was operational
   Total Outage Duration	Displays the total downtime recorded for the monitoring period
   Number of Outages	Shows the total number of incidents during which the monitor was unavailable
   Monitor Availability Summary
   Total Downtime	The percentage of the total time the interface was down
   Total Uptime	The exact duration the interface was functional
   MTTR	The average time taken to restore the interface after a failure—lower values indicate faster recovery
   MTBF	The average time between failures, showing reliability—higher values are better
   Monitor Suspended Summary
   Total Suspended Time	The time the monitor was paused (if any)
   Total Suspended Time Percentage	The total range of the monitored period that was intentionally suspended
   Total Scheduled Maintenance	Duration of downtime due to scheduled maintenance
   Total Scheduled Maintenance Percentage	The percentage of time the device was down for planned maintenance
   Graphs
   Availability Percentage Trend	A visual representation of uptime and downtime over the selected period Green represents available time, red indicates downtime, and purple represents maintenance
   Downtime Report	Shows a graphical summary of outage incidents—helps in identifying patterns in failures and troubleshooting issues
   Overall Outage Details
   Resource Name	The affected interface name
   Status	Indicates whether the outage was resolved or is ongoing
   From Time	The start and end timestamps of each outage
   To Time
   Duration	The duration of the outage in hours and minutes
   Reason	The cause of the outage (if documented)
   Latest Comment	Any additional remarks related to the outage
   Resource-wise Outage Details
   Resource Name	The affected interface
   Down Duration	The time each resource was unavailable
   Availability (%)	The uptime percentage for each resource
   Downtimes	The number of times the resource experienced failure
