Serviceability (computer) Totally Explained

Everything about Serviceability Computer totally explained

In software engineering and hardware engineering, serviceability (also known as supportability,) is one of the -ilities or aspects. It refers to the ability of technical support personnel to monitor computer products, identify exceptions or faults, debug or perform root cause analysis, and provide hardware or software maintenance in pursuit of solving a problem and restoring the product into service. Incorporating serviceability facilitating features typically results in more efficient product maintenance and reduced costs for technical support.
Examples of features that facilitate serviceability include:

Help desk notification of exceptional events (for example, by electronic mail or by sending text to a pager)
Network monitoring
Documentation
Event logging / Tracing (software)
Logging of program state, such as
- Execution path and/or local and global variables
- Procedure entry and exit, optionally with incoming and return variable values (see: subroutine)
- Exception block entry, optionally with local state (see: exception handling)
Software upgrade
Graceful degradation, where the product is designed to allow recovery from exceptional events without intervention by technical support staff
Hardware replacement or upgrade planning, where the product is designed to allow efficient hardware upgrades with minimal computer system downtime (for example, hotswap components.)

Serviceability engineering may also incorporate some routine system maintenance related features (see: Operations, Administration and Maintenance (OA&M.))
