Once these categories have been considered, specific KPIs can then be chosen based on their relevance to the software management system being tested. For example, if availability is a top priority for the system, then availability-related metrics such as mean-time-between-failures (MTBF) should be included in the list of KPIs.
To better understand how these KPIs relate to overall system performance, they can be organized into a table like this:
| Category | Specific Metrics | Description |
|---|---|---|
| Capacity | Maximum throughput | The maximum number of transactions that can be processed by the system per unit time. |
| Concurrent users | The maximum number of concurrent users who can use the system at one time without experiencing significant lag. | |
| Scalability | Response time under load | How quickly does the application responds when subjected to increased loads? |
| Memory utilization under load | What percentage increase occurs in memory usage during peak activity? | |
| Availability | Downtime duration | Total time between two significant failures or crashes in the system. |
| Mean time to recovery (MTTR) | The average time taken to restore a failed component back into normal operation. | |
| Reliability | Error rate per transaction | Number of errors encountered during transactions divided by total number of successful and unsuccessful transactions. |
| MTBF | Average length of time between two consecutive failures in the system, assuming that it is always repaired immediately after any failure. |
Choosing the right KPIs for performance testing is crucial since they help guide the development team towards improving specific areas of software management systems that need attention.
In conclusion, identifying key performance indicators (KPIs) should be an essential step when conducting performance testing on software management systems. Different categories of KPIs such as capacity, scalability, availability, and reliability should be considered before selecting specific metrics relevant to the system being tested.
