Bandwidth Utilization Review

Inspection template for reviewing circuit and interface utilization trends against capacity thresholds so upgrades can be planned before saturation impacts service.

Inspection Details

• Review date and time recorded
• Network scope identified
  Specify the site, circuit ID, interface name, VLAN, or service area included in this review.
• Review period defined
  State the trend window used for analysis, such as 7 days, 30 days, or 90 days.
• Data source documented
  Identify the monitoring source used for utilization data.

Circuit and Interface Utilization

• Peak inbound utilization within acceptable threshold
  Enter the highest observed inbound utilization percentage for the review period.
• Peak outbound utilization within acceptable threshold
  Enter the highest observed outbound utilization percentage for the review period.
• Average utilization remains below warning threshold
  Enter the average utilization percentage for the review period.
• No sustained saturation observed
  Confirm there were no sustained periods of utilization at or above 85% for longer than the organization-defined threshold.

Trend Analysis and Capacity Risk

• Trend direction assessed
  Select the observed utilization trend over the review period.
• Peak utilization time window identified
  Document the busiest time of day or business cycle when utilization peaks occur.
• Capacity exhaustion forecast documented
  Estimate when the circuit or interface is expected to exceed the warning threshold if current trends continue.
• Business impact of saturation assessed
  Rate the operational impact if the link reaches saturation.

Thresholds, Alerts, and Exceptions

• Warning threshold configured
  Enter the configured warning threshold for this circuit or interface.
• Critical threshold configured
  Enter the configured critical threshold for this circuit or interface.
• Alerting is active for threshold breaches
  Confirm monitoring alerts are enabled for warning and critical threshold crossings.
• Known exceptions documented
  Confirm any approved exceptions, planned maintenance windows, or temporary spikes are documented and reviewed.

Upgrade Recommendation and Corrective Action

• Upgrade or optimization recommendation recorded
  Select the recommended action based on the utilization review.
• Target completion date documented
  Record the target date for completing any approved corrective action or upgrade.
• Responsible owner assigned
  Identify the team or individual responsible for follow-up action.
• Review summary completed
  Summarize the key findings, risks, and next steps from the utilization review.
