What is KPI monitoring

#Question
What is KPI monitoring?
Key performance indicator
To monitor, Detect,and optimize the following basically:
• Retainability
• Integrity
• Availability
• Mobility
*Acceptability
Key performance indicators (KPIs) are essential to the success of any network provider. Those who work in network management should be aware of the role of the KPI in measuring performance.

Examples of Network KPI Usage

Network Operations

In the NOC, technicians use network management software to keep a close eye on the network – while department managers keep a close eye on them. To gain oversight of both the network and departmental productivity, managers make use of pertinent KPIs. Daily, weekly or monthly reports may track mean time to restore (MTTR), availability, number of calls, dropped calls or network congestion. A given network may automatically track hundreds of measurements. Selection of KPIs for reports is at the discretion of managers and senior engineers.

Quality Control

Those responsible for quality control and optimization may look for more finely tuned metrics. Here is a small sampling of KPIs chosen for reports prepared by this writer in a previous 4G mobile project:

Average active users
Average cell throughput download
Average cell throughput upload
Cell availability
Maximum cell throughput download
Maximum cell throughput upload
Upload traffic volume (MB)
The focus and granularity of reports in these cases will depend on the nature of the problem under analysis. How many users or network elements are involved? Which specific technologies are in play? What is the time frame? Such a game of twenty questions can help when setting up the investigation. (For another example of KPIs in use, see How Far is Your Data From Your Analytics? An Overview of the SVoD Analytics Landscape.)

Customer Service

Ticket management and customer satisfaction are the responsibilities of customer service personnel. Mean time to close (MTTC) is one example of a KPI that may be used to evaluate ticket handling. In this arena, it's important to respond to customer needs and requests quickly. Incoming phone calls are tracked, and the evaluation of departmental performance may involve a whole array of KPIs unrelated to the network itself.
