Performance Management

1. 5) Two broad functional categories

1.1. i) Monitoring-tracks activities on the network

1.2. ii) Controlling- Enables performance management to make adjustments to improve network management

2. 7) Network manager can reduce or prevent network overcrowding and inaccessibility

3. 6) Performance metrics does work in two levels

3.1. i) Macro level-Throughput and responses time, availability, reliability

3.2. ii) Micro levels- Bandwidth utilization, error rate, peak load, average load

4. 1) Definition

4.1. Facilities needed to evaluate the behavior of managed objects and the effectiveness of communication activities

5. 2) Performance management goals

5.1. Determine the effective utilization of network resources

5.2. To remove potential bottlenecks and detect possible failures

6. 3) Consist of two components

6.1. i) Evaluates and reports on the behavior of networking equipment and the effectiveness of the network or network element

6.2. ii) A set of various sub functions that includes gathering statistical information, maintaining and examining historical logs, determining system performance under natural and artificial conditions and altering system modes of operation

7. 4) Basic function of performance management

7.1. i) Find utilization and error rates

7.2. ii) Performances data collection

7.3. iii) Performances data analysis

7.4. iv) Problem reporting

7.5. v) Capacity planning

7.6. vi) Performance report generation

7.7. vii) Maintaining and examining historical logs
