Abstract:
1. A method for monitoring a network, comprising: obtaining data associated with one or more network capacity attributes and one or more key performance indicators (KPIs) from one or more cells included in a network during a collection period; determining that an event occurred for a particular time within the collection period, the event being at least one of a network outage and a hardware failure; excluding from the obtained data abnormal data obtained for the particular time of the event and based on the event; calculating network level values for the one or more KPIs from the data obtained from the one or more cells after the abnormal data is excluded from the obtained data; generating one or more performance data graphs by plotting a first of the one or more KPIs against a second of the one or more KPIs, the first of the one or more KPIs being a capacity utilization percentage based on the one or more network capacity attributes; analyzing the one or more performance data graphs by determining a correlation between the second of the one or more KPIs and the capacity utilization percentage to determine a plurality of alarm thresholds including a major alarm threshold and a minor alarm threshold, wherein the major alarm threshold is triggered when network performance is severely degraded, and wherein the minor alarm threshold is triggered when network usage is trending toward degradation of network performance; and monitoring the one or more capacity attributes to determine if any of the alarm thresholds has been triggered.
