Monitor and analyze availability against targets.
To prevent the failure of service system components and support the availability of the system, the service system must be monitored. At a minimum, availability is monitored. Other quality attributes can be appropriate to monitor depending on the type of service provided. Reliability and maintainability are other quality attributes that can be appropriate to monitor for many types of service systems. Resilience of the service system to service component failure can also be monitored and the impacts of specific failures on service system availability can be identified.
Example Work Products
- Alarm data
- Availability data
- Reliability data
- Maintainability data
1. Monitor availability, reliability, and maintainability against their requirements.
2. Analyze trends in availability, reliability, and maintainability.
For some services, it may be advisable to perform failure trend analysis as well.
3. Identify breaches of availability, reliability, and maintainability requirements.
4. Determine the corrective actions to be taken.
